macOS Catalina (10.15) - Problems and solutions in the collective contribution

/ From / Apple, The omniscient garbage dump / 627 comments

With macOS 10.15 Catalina, Apple released its latest operating system at the beginning of October 2019. On compatible models of the Mac, iMac and MacBook you can now install the new OS. However, as every year, there are also a few teething troubles on the Apple computer, which I would like to list for you below. If you know any other macOS Catalina problems and solutions that do not appear in the following list, please leave a comment. I will always expand the article if I come across something for it. For the sake of clarity, have a look at the table of contents of the article;)

Update 29.01.2020: Apple just released the update to 10.15.3. Read more here. I would recommend installing the update as it is sure to fix some issues.

Problems installing macOS Catalina

Besides the macOS 10.15 Catalina download that I already have discussed here Of course, various stumbling blocks can also be in the way during installation. If the Catalina installation doesn't work for you, there are a few ways to solve the problem. First and foremost, of course, to free up space on the Macintosh HD hard drive; because the new Apple operating system requires around 30 GB of memory. Otherwise there are the following options:

Install macOS Catalina in Safe Mode

  1. Shut down the computer (if necessary with a long press on the power button)
  2. Turn it on again and hold the Shift key while booting
  3. Safe Mode starts with the Apple logo on a gray background; then run the Catalina Installer

A little hint: Press cmd + L during the installation process to see if the installation is still running and how long it will take.

Solve Catalina installation problems with PRAM Reset / SMC Reset

On the Apple Mac you can, among other things, reset the Random Access Memory (PRAM) or the System Management Controller (SMC) parameter. What this all means and how the resets work, I have summarized for you here: Instructions: NVRAM, PRAM and SMC reset on Mac - reset to solve problems. Take a look at it; To repeat the information there here would go beyond the scope.

« Inset »If you are interested in MagSafe on the new iPhone 12: I measured it again and found a shockingly poor charging performance. Read more here in my post about the metrics on MagSafe.

Mac does not boot / boot after Catalina installation

Of course, the installation can also run completely smoothly, but then the start of the system will be faulty. If your Apple computer isn't booting properly or won't start up properly, first force the shutdown and then turn it back on. But immediately press cmd+R to boot into recovery mode. When the loading bar appears, you can release the buttons again. Then open this from the Utilities menu window Disk Utility ("Disk Utility" in English). 

Select the Start Volume, i.e. the hard disk from which the system will be started, in the left bar of the Disk Utility. In most cases this will be the “Macintosh HD”. Click on it with the secondary click or right-click and select the menu item "Start first aid ..." In the window that asks again whether you want to execute the process, click on the "Execute" button. When the repair is complete, the Mac will restart normally; that should work now.

The Apple Mac does not boot properly after Catalina upgrade - the solution can be to repair the hard drive in Disk Utility.

macOS Catalina freezes at the login screen

If you want to start your freshly installed Apple operating system and it freezes on the login screen, there is also a solution. The reason can be kernel extensions that come from third-party manufacturers - so-called kexts. A clean Catalina start can be achieved if you move its library folder to a backup folder in the safe mode described above. You can find the kexts in ~/Library/Extensions on the Mac hard drive. Just use the following Port-Command that moves the folder to your user directory:

mkdir ~ / Extensions-Backup && sudo mv / Library / Extensions / * ~ / Extensions-Backup /

General approaches to solving Mac problems

In the following I have listed solutions for many individual problems that can occur after upgrading the Apple Mac to macOS 10.15 Catalina. In general, however, you should always try the following before:

  • If the app is on strike, quit it (cmd + Q) and restart it
  • Restart your Mac if the system is slow or has malfunction
  • If the computer is still slow, the Activity indicator open and end CPU-hungry processes (see below)

macOS Catalina apps are not working

If restarting the Mac app in question, restarting the computer, and other common measures don't work, there's a problem. Perhaps the reason the macOS Catalina apps are not working is their 32-bit architecture. Because only 64-bit apps are supported under the new operating system. You can find a guide to this with this link. You can find out which of your apps is 32-bit and which operates with 64-bit:

  1. On the  symbol click in the menu bar
  2. Subsequently About this Mac choose file
  3. In the "Overview" tab click on the "System report ..." button
  4. In the left menu bar under Software the point Programme choose
  5. Explore the list that appears on the right
Old 32-bit apps won't work on macOS 10.15 Catalina. This is how you can find out which of your programs have a 64-bit architecture.
Old 32-bit apps won't work on macOS 10.15 Catalina. This is how you can find out which of your programs have a 64-bit architecture.

By the way, the solution here is: update the software. Because if the development of the software is still active, there should be an app update to maintain compatibility. If it is an old program for which there is no support or further development, you need - if there is one - an emulator for 32-bit apps. Or another app that takes over the tasks of the outdated software.

External hard drive, mouse, keyboard or printer are not recognized

If peripherals connected via USB or Bluetooth do not work after the Catalina upgrade, this is probably due to their drivers. If the hard drive connected via USB, the mouse or keyboard or the printer do not respond, this could be due to a 32-bit driver that is no longer supported. You can find an update via the App Store, among other things. Alternatively, you can write to the developer (s) if you cannot find an update notice or a new driver on their website either. 

Mac runs slowly after upgrading to macOS 10.15

It is to be expected that some Macs will become slower after the macOS 10.15 upgrade. If your Apple computer runs slowly after installing Catalina, it could be due to one or two solvable reasons. The first one goes by the name fileproviderd and is a system process. Since the new operating system exchanges a lot of data with web processes (e.g. cloud storage), the fileproviderd Process - especially at the beginning, when the new system is synchronized with the web services - together with the mds Process 80% to 100% CPU demand. You can locate the processes, examine them for CPU performance and terminate them in the Activity display (called "Task Manager" in Windows)which you can find on the Launchpad. 

Further solution: Deactivate / uninstall browser extensions

Browser extensions in Apple Safari, Google Chrome and Mozilla Firefox can also cause problems and slow down the Mac. Especially if the browser or its extensions are not yet designed for the current system. How to deactivate extensions in the three web programs:

  • Safari: In the menu bar Safari and then Safari extensions ... click to manage or update the extensions
  • Chrome: Top right on the three points click on in the menu More tools click and then Extensions choose; Deactivate or remove the extensions there
  • Firefox: At the top right on the three strokes Click on Add-ons (puzzle piece icon) click and then left Extensions choose; now manage the list entries

macOS 10.15 Catalina and Microsoft OneDrive do not cooperate

When Microsoft OneDrive If it doesn't work on Catalina, there is a simple solution. I can't 100% confirm the solution works, but other sources say it does. The solution to this Catalina problem lies in creating the connection again:

  1. Disconnect the OneDrive
  2. Log out of the client app (exit app)
  3. Remove the OneDrive folder from the Mac hard drive
  4. Put the whole thing back on again
  5. Alternatively, contact Microsoft support

Pairing Mac and iPad via Sidecar does not work

With “Sidecar”, Apple has created a proprietary option for using the iPad as a second Mac, iMac or MacBook screen. The Apple Pencil can also be used in Mac apps and the iPad can be used as a graphics tablet. This should work with the new iPadOS and macOS Catalina - but it doesn't always do. Sidecar may not work for you because your Mac is too old. Models from before 2015 are not supported per se: iMac from the Late 2015 model, iMac Pro from 2017, MacBook from Early 2016, MacBook Air from Late 2018, MacBook Pro from Mid 2016, Mac mini from Late 2018, Mac Pro from 2019. 

But there is a solution that can work on older Mac models. This again consists of a command for the terminal. If you want to try to use Sidecar on a Mac older than the one listed above, try this command line:

defaults write com.apple.sidecar.display allowAllDevices -bool YES

Sidecar does not work despite a compatible Mac and iPad

Do you have a newer Apple computer and a Sidecar compatible iPad, and Sidecar still doesn't work? Then try first to solve the second monitor function with a cable connection. Connect the iPad to your Mac by cable and try again. If that doesn't work, disconnect the cable again, delete the WiFi settings on the computer, dial in to the WiFi again and try again to establish a wireless sidecar connection. You can find the WiFi settings and the option to remove a network like this:

  1. The  symbol click in the menu bar
  2. In the roll-down menu System settings ... choose file
  3. In the overview on Network here
  4. On the button More options… here
  5. Select WiFi network and click on the - Click (minus sign)

Then try to establish a sidecar connection with the iPad.

Find known WLAN networks and disconnect or delete the saved settings - this is possible in the network overview.
Find known WLAN networks and disconnect or delete the saved settings - this is possible in the network overview.

Download from iCloud folder does not work on Catalina

The integration of iCloud and other web services is one of those sources that always leads to bugs in a new Apple operating system. Until there is a patch with an update version (macOS 10.15.1 or later), there is not much that can be done here. If you cannot download iCloud folders as a whole, then open the said folder and download the files from it individually. That should work.

It can also help to back up the folders locally (copy everything one by one to new folders on the hard drive), then delete the iCloud folders and recreate them. In some cases, the download of entire folders should work if the folders were recreated in iCloud after the Catalina upgrade. It depends on a try ...

Music app or music directory freeze / not respond

The previous operating system, macOS 10.14 Mojave, was the last with iTunes. In the new system, the music app comes along and wants to trill the tracks on the hard drive. If that doesn't work, the app freezes, the search for music files runs endlessly and no progress can be seen, or if other problems occur, there is a solution. Because the problems can arise from obsolete Mojave caches. To solve this Catalina problem, do the following:

  1. Copy your music to a backup folder and delete it from the music folder
  2. Opens ~ / Library (folder on the system hard drive) 
  3. There deletes all elements with the names "Music" or "Music" and "iTunes"
  4. Open ~ / Library / Caches (also on Macintosh HD) and do the same
  5. Restart your Mac and move the saved music back to the Music folder

Following this procedure, new cache files and directories that work should be created. The music app should then run without any problems.

Too many notices and warnings are displayed

Unfortunately, this is a problem that you have to live with for the time being. Because the increased security of the system is responsible for the many warning notices, approvals for individual processes and the like; there is no workaround. Either you have agreed to everything (yes, App XYZ can access the calendar, and yes, Safari can save the download of the ABC page, ...) or there is a patch for it. We shall see which applies first.

Bluetooth doesn't work in macOS 10.15 Catalina

The problem also seems to exist every time an Apple operating system has been upgraded. But don't worry if Bluetooth doesn't work with Catalina. There is a solution for this: simply delete the Bluetooth.plist files. This is not a problem, as they are automatically recreated - ideally so that the radio connection works afterwards. And this is how you proceed:

  1. Opens the Finderso that its window is active
  2. Click in the menu bar Go to and then Go to the folder ...
  3. Get to the folder ~ /Library / Preferences bring 
  4. Deletes the file named com.apple.Bluetooth.plist
  5. Restarts the Mac and tries to establish a connection

Doesn't that help yet? Then take a look at this more detailed guide: Bluetooth Problems on Mac - 4 Measures That Can Help! There you will also find the instructions for resetting the Bluetooth module on the Mac.

Safari extensions have stopped working

With macOS 10.15 Catalina, Apple is taking a further step in the convergence of the computer operating system and the iOS and iPadOS mobile systems. As a result, some extensions for the Safari web browser are no longer supported if they are based on the WebExtensions format. This is the case with .safariextz files. There is no direct solution to this, only the option of using a different browser in which the extensions or their substitutes work. I have listed above how you delete extensions that no longer work or cause problems.

The hard drive fills up for no apparent reason

If, after upgrading your system, the free space continues to decrease because your Mac's hard drive continues to fill up, then it's probably due to Time Machine. The Time Machine backups and copies of APFS snapshots are likely to be stored in different locations and reproduced over and over, so that free space is slowly running out. 

To see how many snapshots there are already and which data they show, you can have them listed with this terminal command:

tmutil listlocalsnapshots / System / Volumes / Data

The command lists the local APFS snapshots of the Time Machine. If you no longer need them and therefore want to delete them, you can do that with this command (adjust the date in the appropriate place):

deletelocalsnapshots

Alternatively, you can download a free test version of CleanMyMac X and thin out the Time Machine snapshots in the maintenance area of ​​the app. Details about the software and the link to the download page can be found here: CleanMyMac X - anniversary version with malware removal.

Battery empty quickly: MacBook battery does not last as long

If the MacBook battery runs out quickly after upgrading to macOS 10.15 Catalina, then you are also dealing with a well-known problem. No matter if Mac, iPhone, iPad or other Apple device; It is not uncommon for there to be a bug or certain processes that empty the battery before the first patch and bug fix. 

I already mentioned the activity display above; here again the contribution to it. In the Apple counterpart to the Windows Task Manager you will find the running processes and their consumption of processor (CPU), memory (RAM), energy and so on. You can end hungry apps with the X symbol in the top left above the list. You can eliminate unresponsive apps via the  menu with "Quit immediately".

Mail app freezes or freezes under macOS Catalina

The comments on this post often included references to the mail app and its problems under macOS 10.15 Catalina. Sometimes the program crashes, sometimes no new emails are received, sometimes the app freezes. There are very different hurdles if you want to continue using Apple's own client for emails after the macOS upgrade. That's why I looked for solutions and found them.

Before you carry out the following steps, you should definitely have made a backup. Since you've just upgraded to Catalina, I'll just assume that you have a backup copy of your hard drive and thus also your mail library. Well, let's tackle troubleshooting:

  1. If possible, closes the mail app (if necessary via  -> Exit immediately)
  2. Opens the Activity indicator and ends every process with “Mail” in its name

  1. Closes the activity monitor and opens a Finder-Window
  2. Call your user library via the folder structure and in it Saved Application State on or ...
  3. ... clicks in the menu bar Go to -> Go to folder ..., enter ~ / Library / Containers / com.apple.mail / Data / Library / and open the Saved Application State folder

  1. Deletes the com.apple.mail.savedState folder located in it
  2. Now go to ~ / Library / Containers via the preferred route
  3. Moves com.apple.mail and com.apple.MailServiceAgent from there to the desktop or another backup folder outside the library
  4. Deletes the following data from ~ / Library / Mail / MailData (or ~ / Library / Mail / V6 / MailData): Envelope Index, Envelope Index-shm and Envelope Index-wal

  1. Empty the trash and restart the Mac

When the mail app finally runs smoothly after this procedure, you can delete the files that have been moved to the desktop or another backup folder (see step 8). Otherwise you should push them back into the folder from which you took them (see step 7).

E-mails and e-mail content are not (correctly) displayed after Catalina upgrade

Again, this can be an issue that occurs after upgrading the Mac operating system. So if you can look at the header information of your emails without any problems, but cannot find the content of the emails, you can try the following solution. This should also help if the formatting of the emails in the client is shifted, too small or otherwise strange:

  1. Open the Mail app so that you can see the mailboxes in the left sidebar
  2. Click on a mailbox to mark it
  3. Click on Mailbox in the menu bar
  4. Select the Restore item in the drop-down menu (at the bottom)
  5. Repeat points 2 to 4 for all mailboxes

If this does not cause the email content to be displayed again, there is another (somewhat experimental) trick: First close the Mail app completely (cmd+Q). Then uninstall all anti-Virus-Programs, anti-malware apps and similar third-party software. Restart Mail and see if that helped.

After the Catalina upgrade, no mails can be received or sent

It can also happen that after upgrading your Mac, iMac or MacBook you can open the Mail app and view all your mails as usual. The only difference is that no more new e-mails are loaded and no newly written e-mails can be sent. There is also a procedure for this which can represent the solution to this Catalina problem. It is a two-part approach; the first steps are as follows:

  1. Open the Mail app and click in the menu bar Window
  2. Now select in the menu that opens Check connection from
  3. If all connections are displayed in green under "Status", continue with the next list of measures
  4. Otherwise, check the box for “Protocol for connection activity” and click on the “Check again” button
  5. Now click on the "Show logs" button and look in the txt logs to see whether connection problems have been noted

If the connections have changed to a green status after checking the connections again, you will try again to send and receive e-mail. If sending and receiving does not work despite the green status of the connection, you can also remove the accounts in question from Mail and add new ones. If this does not bring any improvement, proceed as follows:

  1. Opens the keychain management (cmd + space bar, then Keychain management enter and press enter)

  1. Enter an @ (at sign) in the search bar at the top right
  2. Select the account (s) in question from the list
  3. You can delete the entry with a right click
  4. Then open the Mail app
  5. Click in the menu bar Email and then Settings ... an
  6. Select the "Accounts" tab in the settings window
  7. There delete the mail account whose keychain entry you removed
  8. Adds the account back with all the details
  9. Close all apps, restart the Mac, and try receiving / sending mail again

Mail still doesn't work: interim solution!

There is an interim solution in the event that the above approaches do not work for you and there is no update or no bug fix from Apple yet. The solution is that you register with the individual providers via their website and use the web browser to view your new e-mails and send them yourself. From GMX via the web and G-Mail to Yahoo and Co. it should work without any problems. You can also check your @ icloud.com emails and send them via the iCloud website.

Adobe and Catalina I - problems with Photoshop

Photoshop 10.15 and newer versions are compatible with macOS 20.0.6 Catalina. Problems can arise with older versions. If the 32-bit versions are concerned, they will no longer run on your Mac after upgrading the operating system. However, if your Photoshop app is still working, these problems can occur:

  • Problem: After selecting the storage format, the file format abbreviation is not changed
  • Solution: Change the file format in the file name yourself before saving

and / or

  • Problem: "Copy" does not appear in the file name even though "As a copy" was selected
  • Solution: Add the term “copy” yourself or something else to distinguish it

There may also be other problems that Adobe at this point performs. In the document you will also find solutions to overcome some hurdles with terminal commands.

Adobe and Catalina II - Problems with Lightroom

Even with Lightroom there can be problems on the Mac after upgrading to macOS Catalina. Adobe has that in this document shown. According to the linked page, the versions from Lightroom Classic 8.4.1 and other 64-bit versions work with Catalina, but there are also minor operating problems here. For example, Nikon cameras are not recognized when tethering. In addition, the Lens Profile Creator in Lightroom does not work under Catalina - simply because it is still based on the 32-bit architecture. For both problems there is no real solution yet (except pictures from Nikon camera via cable or memory card exchange); Adobe is working on it though.

Catalina problems with products from "Native Instruments"

If you work as a DJ, DJane, musician or other audio nerd with the products and apps from Native Instruments, then you should refrain from installing Catalina for the time being. Not only does the new operating system take away the iTunes app with its directories and other advantages to which you have become accustomed. You also lose XML file support with macOS 10.15. Many DJ apps like Rekordbox or Traktor read XML files and need this support. Therefore you should wait for updates and patches from Native Instruments or from other developers whose apps you use.

Catalina problems with the Hazel app from "Noodlesoft"

Noodlesoft has the Hazel app for the Apple Mac, which helps organize files and folders. I received the following information by email from the developers and from Chief Paul Kim (translated from English, abbreviated): 

[...] Apple has just launched macOS Catalina. Unfortunately, it contains numerous bugs, unannounced changes, and other things that affect Hazel. If Hazel is important to your workflow, I strongly advise against upgrading to Catalina at this point in time. 

I'm currently working on a version that will work around a lot of the problems, but this is proving difficult [...] In case you're interested in checking out the latest Hazel Beta, the details can be found on the forums [...] I'll also send you an announcement when Hazel is compatible with Catalina. [...]

      Hello Erol! Sorry, I did not understand the explanation of the error. Why should Mail restart by itself when you close it?!?

        Hello Arnd! Unfortunately, I don't know exactly what it could be. But I would try two things:
        1. Restart the Mac
        2. Hold down CMD + R while booting and then install Catalina again over it (no data will be lost).
        Let me know briefly whether it worked afterwards! Thank you and happy holidays!

        Update December 24.12.2019th, XNUMX: I received an e-mail from Arnd: After installing it over it, his Catalina runs more stable and faster, but the problem with the internet no longer working was due to two wrong IP addresses that were stored under Network> DNS. After these have been removed, everything works again.

    Hey!
    Since the update I can unfortunately no longer connect to my FritzBox in the home network. It works fine on my old Mac. Can you do anything there?

      Hello Lukas! Do you have two WLANs in operation? Or a repeater? I have the effect on me because Google Wifi does the WLAN for me, but the Fritzbox also has a WLAN. When I'm connected to the Google Wifi it works with that http://www.fritz.box Not. This is only possible if you are directly in the Fritz WLAN. Otherwise I would try a restart or switch the WLAN on and off on the Mac. The fault shouldn't be due to Catalina.

        I guess I put myself wrong! I use the FritzBox as a small NAS storage device. Can connect to it using my MacBook Air without any problems, but not the iMac that has Catalina installed on it. It is displayed under Network, but I cannot connect even though I have entered the correct access data.

        1. sir appleot

          Ah ok! This is a problem that is already known: The new Catalina has thrown out support for SMB 1 because it is considered unsafe. Unfortunately, the Fritz! Box only supports SMB 1 in the NAS area and no new protocol. According to AVM, the support should be delivered later, but no date has been set for it. I hope they get enough Catalina users on the biscuit to hurry up. But within a few days that will certainly not be the case.
          It is currently recommended as a workaround to access the Fritz! Box NAS from your Mac via FTP.

          1. Goofer69

            If you absolutely need SMB 3 support on your Fritz-Box, you should take a look at the laboratory versions (beta versions) at AVM. The support is already included, just to test it.

    Good morning, Catalina installed the night before last. I have a MacBook Air 2015. I have the bug, when I open an application, then the menu bar at the top, where I can change the settings of the program, for example, does not click. I have with some applications. Does anyone else have the problem and can they tell me how to solve it? Or is that a bug that will be fixed by an update?

    Hallo,
    yes, I am one of those who couldn't wait ... Apparently the memory was calculated incorrectly during the update, so that the installation cannot be completed. I see the hard disk as an image file in the disk utility. There is probably no way to delete items from this file? In addition, the connection to the TimeMachine is not established. I'm a little desperate right now.

    1. sir appleot

      Hello Gferno! Why is there an image of your hard drive? Did you have one made? Otherwise you can try to make some space via "Apple menu > About this Mac > Disks > Manage".
      Because of the connection to the TimeMachine: I think there is no access when the installer is running. If I understand you correctly ... I keep my fingers crossed that it will still work!

    Hallo,
    after installing 10.15 I have problems with the new books app. The existing synchronization between IOS (13.2.1) and the books app does not work because the authorization of purchased content (here: Audible) is not recognized. Deauthorizing the Audible account and re-authorizing it with Audible only leads to the goal after a number of attempts. I cannot see a systematic why it works sometimes. After restarting and re-syncing with the iPhone, all audiobooks on the iPhone are deleted again because the authorization is not recognized again. And everything starts all over again (and the groundhog greets forever). Since it previously worked fine under Itunes and IOS 13.2.1, I suspect Catalina was the culprit. Is there anything known about the problem? - Thanks and regards

    1. sir appleot

      Hello Thoari! Unfortunately I don't have a tip ... I think this is a problem that will be fixed in one of the upcoming versions of Catalina. Apple itself recommends deactivating iCloud on the Mac and reactivating it later if you have such synchronization problems. Maybe that helps with you ... but I'm guessing more of a bug.

      I have the same problem, my iPod classic no longer takes audiobooks, only sporadically one or two are taken over and then again not. I can't see any system behind it either. Maybe you can leave a message here if you have a solution.
      Thanks Mike

      The problem still persists, but I have now found a workaround that does not solve the problem but reloads the deleted audiobooks with every Iphone Sync:
      1. Deauthorize Audible in the "Books" app (menu store)
      2. Deauthorize in the Audible Shop (browser)
      3. Double click on the audio book in "Books". Error message that authorization is missing and confirm.
      4. Activate iTunes or "Books".
      5. Start Sync in the main menu "General" of the Finder at the bottom right. The progress can be traced using the progress circle

    I have a Mac Mini late 2012 and can't even install Catalina. After half an hour I get an error message that the OS could not be installed. Verifying or repairing the storage system failed. : (-69716)

    I've tried several times but always the same message.

      Hello Pablo! This is a message pertaining to your system hard drive. Have you perhaps installed an SSD? Otherwise I would plug in an external hard drive and try to install the system on it and then, if necessary, pull the data over with the migration assistant.

        Hello, yes, I noticed that. An SSD is built in. It couldn't be repaired so I restored everything. Now I'm trying to install again! Let's see…..

        I will report….

          Yes, the SSDs often cause problems with new macOS versions. Sometimes there are firmware updates on the manufacturer's website, but probably not that early. Maybe it will work on the second attempt. I keep my fingers crossed and look forward to the report!

        Good evening,
        I have an iMac (Retina 5K, 27 inches, end of 2015) and also get the message (-69716).
        However, I don't have an SSD but the standard Fusiondrive with 2 TB.
        What can I do?

          Hello!
          The recommendation from Apple Support is:
          1. Restart your Mac and hold down CMD + R
          2. Start disk utility
          3. Select the affected disk and click "Repair".
          4. Restart your Mac

          I hope this helps too.

      Hi Jean! Does Mail end with an error message? Or just without a message? I would also recommend recreating the mail DB with the free Onyx tool. But caution is also advised here: There is still no version that has been sufficiently tested with Cataline. The developer does not want to finish this for about 10 days.

    Catalina: My mail program is causing problems. After a short period of use (<5 min.) The message appears:
    "Mail can't back up information about your mailboxes because there isn't enough space in your home folder."
    There are 350 Gb free on my HDD, there were no problems under OS 14.
    The mail folder in Library is 6,7 Gb in size. What can I do?

      Hello Hans! I would have the mail database re-created with the Onyx program. If that doesn't help, it's probably a bug that has yet to be fixed.

    Catalina has a serious problem restoring a Mac using the Time Machine. The recovery always stops after about a third due to an unknown error. So the way to Apple Support was inevitable for me. After the repair, I was told that the same case had already happened unusually often.

    Since I did the Catalina update, my word program version: 14.5.4 no longer works. If you had a suggestion for a solution, I would be very grateful.
    If I had known beforehand that the 32-bit programs would no longer work, I would not have made an update with Catalina. Unfortunately I did not inform me beforehand.

      Hello! Actually, macOS Mojave has been constantly throwing warnings at its head for the past year that a program will soon no longer work because it does not run on 64-bit. But you are certainly not the only one who clicked away and ignored the warnings.
      Ultimately, you can now only use an alternative such as Pages or OpenOffice or Libre Office, with which you can also open your Word documents, or you can book the Office 365 subscription from Microsoft. I bought this because I often receive documents in Office formats and the alternatives often destroy my layout.
      But there is not much more you can do. The 32-bit Word will definitely no longer run under Catalina ... :(

      1. sir appleot

        Hello Dirk! Are you using the original Apple cable for the connection? The iPhone does not like some cables because they are not MFI certified. Then only charging works at a low level, but no data transfer. It can also happen with such cables that it worked for weeks and then at some point no longer. This is typical for these non-certified cables.

      I had the same problem. I then went to Music (the new Catalina app) and got the message that my music was from an outdated iTunes version. I then created a new one, opened the Books and Podcast apps to be on the safe side, ejected the iPhone and reconnected it and it was read in.
      To make a backup, I had to eject and reconnect the iPhone.

      I was able to solve the Xcode update problem on several macOS installations as follows:

      2. Reinstall Xcode via the AppStore

    Hello and thank you for the many proposed solutions.
    After switching to MAC over 10 years ago, I NEVER had such problems after an update.
    I can practically no longer work.
    It started with the same mail problem as Hans "Mail cannot back up information about your mailboxes because there is not enough space in your home folder."
    Later, I could not save or download any files but got the message "Error - disk full". And all this with an iMac from autumn 2018 with a 2 TB SSD on which 1,64 TB are still free!
    The worst: Adobe Audition - which I need every day for professional voice recordings, no longer works at all. It gets stuck during recording, immediately crashes while cutting, and no longer exports or saves files. Adobe Support is not responding!
    It's only a minor evil if "Photos" also crashes and other "little things". no longer work.
    I don't know what to do :(

    1. sir appleot

      Hello Christian! Honestly: I'm sorry such crap happened. I know what it is like when you have to rely on the computer and then suddenly nothing works. I can only say again and again: If you need your Mac for daily work, you should only install such large updates if you have at least one backup (and by that I don't mean Time Machine, but a 1: 1 clone). The better way for production systems is definitely to wait until the next .1 or .2 version is out. So in this case 10.15.1 or 10.15.2.

      I haven't updated myself yet because I need my Mac for an urgent job and don't have time to make backups if everything goes wrong. I think I'm still waiting for the first bugfix versions to come out. @Christian: I hope you can get your Mac going again ...

          Hi Peter! We had already discussed and solved the matter by email, but I wanted to briefly add what it was: If a window keeps losing focus "as if by magic" and the Mac makes a sound, it's usually in the wrong place because it is trying to start a process in the background that is supposed to run continuously. This crashes (for whatever reason), causing the Finder to come to the front, the Mac playing a warning sound, and the window you were working in losing focus.
          Most of the time, there is a problem with antivirus software that no longer runs after updating to Catalina, for example, because it is not programmed for 64 bits. That was the cause for you. For other readers it was also an old Microsoft Office version. So here you have to do a bit of research into the causes.

        Hello Sir Apfelot,
        I also have the problem with the dock bar. However, I haven't connected a second monitor to my MacBook Air 2019. So far I could only solve the problem by logging out and then logging in again. After that, everything works without any problems. I didn't reinstall Catalina, I did a system update. What I also noticed is that the Macbook is slower with some applications than with Mojave

        1. sir appleot

          Hello, Jens! Ah ok. Of course, the instructions will not work without a second monitor. : D Then I don't know now either. Perhaps an NVRAM reset will help here (hold down Option, Command, P and R when restarting)? Because it slows down after the installation: This kind of thing and also faster draining batteries are usually things that either take care of themselves after a few days or after the first bug fix. It is possible that the Mac is just rebuilding the Spotlight index because something has changed technically. Then this may slow down the Mac a bit until it is done with it.

            Hello Sir Apfelot,
            I think I've identified the problem, at least for me. I reinstalled the Mac several times on the weekend because I saw that an "Installer Progress" was started after each boot and login. Then the dock is gone. Since I no longer installed Microsoft Office 2019, the error no longer occurs. Just for info in case others have the same problem. By the way, this is my first Mac, so I still have to familiarize myself with the topic a bit ... :)

    2. Matze

      I found the problem, but afterwards you have to paste the apps back into the dock bar as the dock was before.
      So the following:

      1. Go to the finder
      2. Hold down the Option key and click Go on the Finder menu bar.
      3. Click Library
      4. This will open the library folder
      5. Click the Preferences folder
      6. Find the com.apple.dock.plist file
      7. Delete this file / folder (move it to the trash and empty the trash)
      8. And restart your computer

      After that the dock is like after a new installation. However, you have to add the respective apps yourself.

      Hello Luis! Catalina actually saves the contents of Books in this folder:
      ~ / Library / Containers / com.apple.BKAgentService / Data / Documents / iBooks / Books / Audiobooks
      The "trick" is usually to create a symbolic link that points to another in that directory. However, this no longer works with Catalina. For that reason, I don't know of any method that could be used to move this location.

    A GOOD morning to the Catalina-damaged group,
    I don't use the cloud, so I synced iPhone and iPad with iTunes using a USB cable. When I tried to do this with the Finder for the first time, all all-day appointments on the iPhone in my calendar disappeared. They are still displayed in the MacBook. Is there any idea how I can get this synced back into the iPhone?

      1. Helmut Arndt

        I kept trying and found a solution for me. Since I made a backup or synchronization with iTunes before the update, I carried out the “Replace calendar” setting. So I have the deleted all-day entries back in the iPhone.

        Why they disappeared, however, remains a mystery.

        Now I'll sync the iPad - let's see what disappears. ????

          My private "test series" is now over - the same problem everywhere with 2 iPhones and 2 iPads: During the first synchronization, the all-day entries disappeared on all devices, but were there again after the 2nd run with the "Replace calendar" setting.

          For all wired synchronizers the urgent recommendation to synchronize again with iTunes BEFORE the update.

      3. Reboot (helped some people too)

      Hello Manuel! I found this effect in an error description for another macOS. This has also occurred with the user. The reason was this: An app running in the background crashes and restarts, crashes and restarts ... every 10 seconds or at a similar interval. For him it was a backup service that was supposed to run in the background, but kept crashing.

      You can find the app with the activity monitor. Open this and close all other apps. Then sort the list by CPU usage in descending order and see which program pops up there from time to time. That should actually be what you have to remove from the Mac so that everything runs “normally” again.

      Once you've found the app, it would be good to know what it was called. If other users have the same problem, they know what to look for. : D

        Hello Dieter! I just posted the solution to Manuel's comment. That should help you too. The cause is a program that should actually run continuously in the background (e.g. a backup service or something). But it crashes and then restarts automatically. This then becomes an endless loop that slows down the Mac again and again and steers the focus away from the active program.

        Hey guys, I'm totally dissatisfied with the new Catalina. At first the download broke off several times and then the installation hung in the last step of the installation during configuration. Now to my current problem: My MacBook Pro 2012 with SSD usually went into standby mode after an hour, so to speak, into deep sleep and used almost no power. The white LED then stops pulsing. Unfortunately that doesn't work anymore. I have already done a PRAM / SMC reset and created a new test user, but everything did not help. I really don't feel like reinstalling everything because of that. Does anyone have an idea or also the problem?

      Do the restarts occur with a high CPU load? Or is there any other thing you can attach them to? Sometimes a defective memory stick is to blame for such reboots, which come out of the blue. Or there are still bugs from Catalina. I would never provide a production system with the first new version of a major update. Always wait from 10.15.1 or 10.15.2. Then most of the bugs are fixed.

        I had to go to repair, but nothing helped. The EFI-Flash and the SMC were probably replaced and re-flattened! It cost me about 300 €, but in the course of that I installed a 1T SSD, so plus 149 €, so 450 € plus two weeks no Imac. Shit happens ;-) life goes on ...

    Hi,
    After installing Catalina, I have the problem that I can no longer transfer my video data from my Sony Handycam FDR-AX53 via WiFi. The cam connects well with the access point (WLAN router Fritz Box) but from there the data does not seem to arrive at my iMac 21,5 late 2015. I need help urgently as I have to work with the cam every day. Can't unscrew it from the tripod and connect it via USB every time.
    And a big compliment to Sir Apfelot for the amazing help that you read here!

      Hello Martin! That could be the same problem, which is why the Fritz! Box NAS no longer works: macOS Catalina no longer supports SMB 1 (and I think 2) no longer. That will not happen any more, because Apple considers this transmission standard to be insecure and only supports newer SMB versions. So either downgrade to Mojave again or get used to the USB cable in the future. :-( And thank you very much for your praise. I'm very happy!

          Hello Martin! I'll write an article about that next week. But in principle it works like this:
          1. Back up your Mac
          2. Download macOS Mojave from the App Store
          3. with the program Disk Maker X create a bootable medium
          4. Restart your Mac and hold down CMD + R
          5. Start the hard disk service program in the recovery partition that is now running and delete the internal hard disk with Catalina (first make sure that you have made a backup !!!!) (when deleting as Format APFS)
          6. Recreate the Mac from the bootable medium and install macOS Mojave on the old system hard drive
          7. Restart Mac and hold CMD+R, then select "Restore Mac from Time Machine Backup"

          So you should actually have the old system again ... If you have created a 1: 1 backup (not with Time Machine), then you can simply iron it over the Catalina disk. This should be the fastest option, but a lot of people work with Time-Machine, so the instructions above.

      Hello Axel! Thank you for your feedback signal. Could you take a quick look to see if secondary click is enabled in System Preferences > Mouse? That would be the corresponding function in the settings... maybe it just changed during installation and you have to activate it again.

          Ok, that's weird. Have you already tried restarting? If necessary, I would then try to install the system again over it. Your data will not be overwritten, but maybe a few new caches or something similar will be created. Maybe that helps. You could also do that Safe-Mode try out.

    I have a 2015 MacBook and I cannot install the Catalina at all. Before I had the Mojave on it and then the update to Catalina came. I downloaded it and hit install. So far everything worked as it should. Now the Mac is installing. Black screen …… Apple logo and underneath there is still 21 minutes and that's for 2 hours. Now and then I hear a tone and the Mac restarts and after booting the same …… .black screen …… .Apple logo and 21 minutes He's been doing that for 1 hour now. what should I do?

      Hello Mirko! Try restarting the Mac (or rather it does it all the time). Then hold down CMD + R and install the current system over it again. Then the Mac restarts. Now I would eject the Catalina installer from "Programs" and reload it. Something seems to have a quirk there. It might work if you start it all over again.

    After updating to 10.15 Catalina, my fan always runs very high and the book gets very hot. After researching the cause, previous status: When I close the CalendarAgent in the activity display, the fan shuts down immediately. Is there a connection? Are there any other experiences? Is there more information about processes that take place in the background?
    I also had sync problems with the calendar, logged out and logged in on all devices and merged all data, not replaced. So I had a lot twice and deleted a lot manually, online in the iCloud and on the book in parallel. Is there a connection?

      Hello Bastian! I read about the CalendarAgent process on an English forum. It said that Siri was probably trying to interpret a calendar thing in some text and start over and over again. The solution seems to have been for the others to check the "Calendar" item under System Preferences > Siri > Siri Suggestions & Privacy. If you don't use Siri on the Mac, you can also turn it off completely... then the CalenderAgent should no longer generate the CPU load.

      Hello Robert! Could this be an iCloud sync problem? I think there have been a few reports in the last few days ... Otherwise it could be that the Mac first loads all the photos into the cloud and only then fetches the edited photos. I guess this is a problem that will go away over time.

        Hello Sir,

        unfortunately the problem has not yet been resolved. To be honest, I don't ask myself any more advice, it's incredibly annoying when it no longer works, i.e. when it is synchronized.

        I have the link to 2 pictures on dropbox one is from the iPhone on which it is easy to see that I have edited it, the other is from the mac on which you can also see that it has been edited, only the bars of the adjustments are at 0
        maybe someone can help me if he sees the pictures. I don't think that has anything to do with sync problem.

          So it syncs the edited photo but not the adjustments? It's really weird, but it's the same for me. :D I've just tried it on myself and the changes are accepted, but don't appear as changes to the controls. But I can click "back to original" and go back to the original photo. For me, I would say it's because I'm using iOS 13 on the iPhone, but only Mojave on the Mac. The two photo programs are different, so I think that's the reason. But if you're on iOS 13 and macOS Catalina, it should work. But I don't know if I'm just thinking it or if it's really like that.

            So I have Catalina and ios13 but if that's the case with you under Mojave then it can of course be that Apple still has to adjust the photos app, everything else would make no sense as it is currently.

            But now I have another problem with IOS13.2
            When I update apps, they load very slowly. I need 15 minutes for a 60mb app, for example, and it doesn't matter whether I want to update the apps with my 100mbit line from home or via the LTE network.
            What could be the problem? I have already reset the network settings of my iPhone 11 Pro and restarted the iPhone several times without success

            The problem is multiple in the forums. We agree that it's because of the Apple TV +. It started on Friday and now the servers only seem to be busy streaming. I haven't received any emails since yesterday ... it's extremely annoying.

    I installed Catalina on my 2018 Mac mini yesterday. Now I have the purple screen phenomenon.

    The monitor (Fujitsu Siemens LSL 3260W) is connected to the Mac mini via HDMI and ran smoothly under Mojave. Since the update I have this purple color cast in the picture.

    As a test, connected to a TV set (Panasonic), this color error did not show up in the display. The HDMI cable is also not the cause of the error, as two more also produce the error and the plug connections are stable.

    The fascinating thing about it is this.

    I still have a 2010 MacMini (HighSierra) here. When I connect this to the monitor, I get a normal picture.

    If I then separate the 2010 (HighSierra) and the 2018 (Catalina) again, the color cast stays off and I have a normal picture until I restart the computer or wake up from the idle state in which the monitor itself is also in the Standby has changed. I also lose the clear picture (which I received via the way described above) and get the purple tint again when I switch the monitor off and on again.

    I've already tried to change the resolution and the color profile. Resetting the SMC as well as the NVRAM did nothing to change the problem. Clearing the system cache by restarting in safe mode wasn't helpful either. Neither does switching to a new user account, which makes it clear that it is a system problem.

    Back to the 2010s. When I connect this to the monitor and start, I get the clear normal picture, as I said. However, if I already disconnect the monitor from the 2010 while it is still showing the loading screen with the apple and the loading bar and then connect the (running) 2018, then the picture remains purple. Only when the 2010 has completed the startup process so far that it has switched to the desk and then I pull the HDMI connector and plug in the 2018, the picture also appears in the normal colors.

    So the cause must be somewhere rather late in the start-up process.

    Currently I'm confused and at a loss.

      Hello! This seems to be a problem that occurs with older systems as well. The instructions are:
      1. Install this software: https://github.com/xzhih/one-key-hidpi
      2. In the software, select option 2: "Enable HIDPI (with patch)".

      During the installation, only the monitor that shows this purple screen should be connected. All others should be staked out. I hope it helps.

      Edit: I read another tip: Check System Preferences > Accessibility > Display to make sure you don't have "Invert Colors" or something enabled for the monitor.

      Reply
      1. BlueFalcon

        Thanks for your tips. However, before I download any software whose function I do not fully understand, I see whether I can not isolate the problem further.

        I've already come a little further. The screen must not be switched off or disconnected from the mains, otherwise the Mini (2018 Catalina) will show the purple screen again. Fortunately, I have the old Mini (2010 High Sierra) here to reset, so to speak.

        Up until now I had the Mac as the master in a master-slave bar and this only activated the screen when the Mac was started (and the rest of the secondary peripherals such as label printers and the like). Therefore, I also had the problem that even after a sleep state in which the Mac switched off the rest of its appendages, the monitor was also switched off and then showed the purple screen.

        I have now solved the power supply a little differently and connected the monitor separately. So I can put the Mac (2018 Catalina) to sleep or switch it off without the purple screen becoming visible after waking up or booting, as long as I don't switch off the monitor myself (or pull the plug). Even if the monitor goes into the device's own stand-by mode due to a lack of signal, the picture remains in its normal state.

        So I narrowed down the problem to the HDMI driver of the Mini 2018 with Catalina, which apparently should send a corresponding color signal to a monitor that is switched on "newly", but sets it incorrectly in this case.

        I've asked around and my problem doesn't seem to be that seldom. In other forums there are also reports about this phenomenon, sometimes more and sometimes less pronounced. For some, only the start screen is colored purple, for others, like me, the entire display. With some of them, the color scheme is rather blue.

            No, no ... it wasn't because you're a bad scribe. I didn't get the technical connections between the purple monitor image and the master-slave connector strip at first. : D

          3. BlueFalcon

            Well, I could certainly have described it better.

            The problem is now limited to the extent that it can be found causally with the HDMI driver and is a faulty HDMI handshake with the monitor, which leads to incorrect recognition of the color system.

          4. BlueFalcon

            Update

            So I'm one step further. I bought another external SSD and installed a Mojave system there with a little effort. After I started from there, the picture was flawless with no falsifying coloring. Which clearly identified Catalina as the cause.

            However, after going back to the internal SSD as the boot drive, that seems to have resolved the problem as well. The Mini now (so far) shows the normal picture, even after the screen has been switched off and on again.

            Apparently, the parallel installation of Mojave on the same computer changed the setting in the HDMI driver somewhat, which at least temporarily eliminates the purple screen problem.

            Should changes occur, I will report again.

      Hello Jan! I had something like that with a Fritz! Repeater. There were problems because the device seemed to get mixed up again and again because the repeater had a WLAN of the same name. I would recommend leaving a WLAN over and switching off the rest. And then try turning the WiFi on the MacBook Air off and on again. Sometimes that helps.
      And there are also cases where external USB devices interfere with the WiFi. Possibly also disconnect and test everything here. It could be a USB 3 hub or something similar that interferes with the WiFi reception.

      Hello Dirk! Yes, there still seems to be a lot of problems with Mail. Currently I would make these recommendations:
      1. Run Mac ... sometimes it just needs to re-index some internal stuff or something
      2. Install Catalina over it (this works without data loss)
      3. Delete the mail index (this is quite easy with the Onyx software)
      4. Hope for macOS 10.15.1 ...

      At the moment the worm is still in there in many places. Sometimes restarting or reinstalling Catalina will solve the problems, but that's all just poking around in the dark. Most of the things are probably with Apple ... and one can only hope that they will quickly post a bug fix.

    Hi Jens,

    For me, the installation of Catalina basically worked without any problems, but now another problem annoys me:

    When I take a screenshot (cmd + shift + 4) it is stored on the desk, but I cannot see it, I cannot click it and it does not appear in the search either.
    If I then reset the NVRAM as you described, the screenshot appears ... everything is good. However, the next screenshot shows the same problem again. Between the reset and the next screenshot I didn't change anything, didn't do anything, and didn't start any programs.

    Resetting the NVRAM makes the file visible again, but it doesn't fix the problem!?!?!?

    Hello!
    I (unfortunately) installed Catalina two days ago on my iMac (end of 2015).

    After the update to Catalina, all my project data disappeared from the local folder of the Next-cloud. I was able to re-synchronize this on the computer. MAIL, Indesign and other programs keep saying that they don't have enough storage space and that they don't work. But that can't be.
    The access rights are also often mentioned that the program does not have the necessary rights. In between I was no longer able to log into the computer with my user password (Admin), after about 30 attempts I had access to my computer again. After that, however, all of my project data had disappeared from my computer. I could go on and on with this list of things that don't work. I'm pretty at a loss.
    I installed the update from yesterday evening immediately. After that, at least MAIL worked again.
    Right now I'm setting up a Mojave laptop so I can go back to work. Maybe you have some advice for me here? Flat out and install Mojave?

      Hello Heike! Maybe I would install Catalina again over the existing system. Maybe that will solve one or the other problem. If not, I would set up the old system again. You can probably use the Migration Assistant (under Utilities) to transfer a lot of data if you should freshly install Mojave.

    I have a fairly extensive music library that I have built up and maintained over the years using iTunes, and which currently includes around 700 playlists. When importing into Catalina's music app, the playlists and albums were taken over, but only about half of all record covers. It is possible to continue to access the old XML library with iTunes for Windows, which I run in parallel in a virtual environment, but do I really want that? After a day, I started Time Machine and returned ruefully to macOS 15.

        The album covers are gradually coming back. I have a collection of over 2000 albums and at first only had about 10% of all covers visible again. I left the music app open and after 2 days I only miss covers sporadically.
        It is annoying that there is no longer any menu item to search for the cover completely in the store, so in stubborn cases you have to initiate the loading of the cover from the store with a right-click. If the cover is not available there (e.g. because this album is not available in your local store) you will get an error message and it will only help to touch it up manually. But I wouldn't give up anytime soon.

    There actually appears to be an update to the update because my Mac is loading one. Is also called 10.15 and was suggested automatically. Is about 1 GB in size. I'm curious what it will bring ... or not :-)

    Hi, since Catalina I have the following problem: Despite all the "network shares" for the access rights (everyone can read and write, I can read and write, restart the iMac), I can access the Mac folders " I can still see Desktop, Downloads, and Documents on my iMac, but won't open them. Windows then complained recently: Z:\\Downloads (Documents/Desktop) cannot be accessed: Access denied.
    So far, however, it worked with the network shares both from Windows to Mac, and vice versa. The two computers are also in the same home network. All other folders on the Mac (even both libraries) can be opened.

    No matter how much I look for a solution, I don't come across any with my Mac Pro 2013, even after the hotfix from Apple, it still runs for a while and then the mouse pointer disappears and it is then unusable, then after approx : 2-5 min it restarts and at the end something like that comes up (which I can't figure out):

      Hi Markus! This type of crash is a kernel panic. Quote from Wikipedia: "Possible causes of a kernel panic are hardware errors as well as faulty memory accesses. However, such accesses and other software errors that result in a kernel panic can normally only be caused by the kernel itself under modern operating systems."

      That means either your hardware is defective (RAM modules are particularly popular as the cause) or there is an error deep in the operating system. That could of course still be the case at the moment. But you could perform an Apple hardware testto see if something is thrown as an error.

        Hi Sir Apfelot,

        I've already done that too, I don't get an error message when I do the AHT, everything should be fine according to this test.

        So you can rule out a serious hardware defect, right? Because if that were the case, I can throw my Mac Pro in the trash because I can't buy a new hardware component. So quickly I can't buy a new logic board or graphics card as a replacement, there would be thousands!

        Frustration spreads and panic!

        what can it be that nothing works anymore? Everything went well with Mojave and there were no problems, I just can't come back to Mojave because it keeps telling me that the hard drive has been changed and cannot be recreated, huh?

        What did Apple do for a mess !?

          I have exactly the same problem with the same computer. No hardware faults to be found either. I created a new user. Then it was pretty stable. I think the old MacPro with old, "grown" users doesn't get along even in 2020 after various updates...

    Hello Sir Apfelot,

    I have a question about Hibernate mode 25 and Catalina. The way I see it, it no longer works properly under Catalina. Up to and with Mojave you could close the MacBook Pro (no Retina in mid 2012) and then the notebook was in deep sleep (Hibernate mode 25) and didn't do anything until I opened it again. Now under Catalina, the notebook apparently only retires and no longer goes into deep sleep. The hibernate mode 25 itself is activated.

    Do you know anything about this?

    Thank you and best regards

      Hello Thomas! The comments are moderated here. That is why they are only visible once I have released them. So now. : D
      Regarding your question: I have the same problem with my iPhone: If I left it with iOS 12 and then unlocked it after a long time and called up the emails, the new ones were immediately visible. Currently under iOS 13, I first have to open Mail for a few seconds and then the new mails will appear one by one. What is it that doesn't work for you under Catalina in Powernap mode? Also retrieving emails? I think this is a problem with the new operating systems that I am sure will correct itself at some point in the next few weeks.

        Hello Sir Apfelot,

        merci for your answer. I just want to close the notebook with activated hibernate mode 25 and then in deep sleep (hibernate mode 25), i.e. nothing at all, but only again when I open it. And that's exactly what doesn't work, the notebook just goes into retirement, ie the LED at the bottom right is always flashing and with hibernate mode 25 it should be completely off. The hibernate mode 25 itself is activated - you can see it via pmset -g.

            Hello Sir Apfelot

            now I have come up with the solution to the riddle. I chatted with a senior advisor from Apple today and he wrote:

            So, theoretically, the mode is still anchored in the code, that is, if you look for it in the terminal, you can set it but because it ran on 32bit, it is currently so that it cannot be activated with Catalina.
            We are currently looking at whether an alternative will be built in, for example on 64bit, but unfortunately I cannot promise whether and when something will be done in that direction.

            So that means, it is not a buggy, but has fallen victim to the 64-bit strategy, and now it's just waiting for the next updates, maybe something happens, maybe not.

    Since Apple Mail doesn't work with GMX IMAP for the time being, I installed and set up "Thunderbird".

    Runs fine! For Apple this is already embarrassing. :(

      Hello Dirk! Do you think it's not going because of Catalina? Basically, Apple Mail works with GMX, if you take the right settings. There are various forum entries and also a help page from GMX. But I don't use GMX, so it could be that there is a special bug in Catalina that leads to problems. But I don't know ...

      Apple Mail also works perfectly with GMX IMAP under Catalina, and I use it myself.

      During the installation process, however, the mail settings can get a little mixed up (for example, the assignment of the folders to my Gmail account). Therefore, I would advise you to simply delete your GMX account from the settings and set it up again using the GMX help pages:

      https://hilfe.gmx.net/pop-imap/imap/apple.html#indexlink_help_pop-imap_imap

      https://hilfe.gmx.net/pop-imap/imap/imap-serverdaten.html#indexlink_help_pop-imap_imap

      Web.de, freenet.de, gmail.com, yahoo.de, aol.de also work smoothly

      With my accounts I had no problems from Catalina except for the folder assignment in gmail.

    BlueFalcon,

    glad you don't have any problems. But the reports about problems with "Mail" on the net speak a different language. There is even a loss of data. Why is Mail writing GBs of data to me?

    Yes, I had already deleted the GMX IMAP account and set it up again. - And it just doesn't work. I've been using Macs for over 20 years and I've never experienced anything like this. And if I get the "Thunderbird" up and running perfectly within a few minutes, I refuse to blame myself. Basta! I'm not as Apple-radiated as so many other "youngsters".

    And there was this problem with iOS too! But after the update to 13.1.3 (!) This is fixed. Not yet with MacOS.

      Let me tell you from experience that there are problems everywhere. Mostly where you least need it. (I didn't know the Purzle Screen problem before either)

      But now to you and mail.

      Check for connections in the Window menu in Mail. If your GMX IMAP account causes problems, then this should then be marked in red. If this is the case, click the "Connection activity log" mark at the bottom of the screen and click "Check again" to repeat the process.

      You can then use "Show log" to identify whether it is an authentication problem or whether something else is the cause.

      The problem can also be stored in the keychain, among other things. If you go to the keychain management (utilities) and enter the @ in the search field, you will see all the mail passwords stored for all of your accounts. Select the affected one and delete it.
      Then you have to go back to Mail and delete the affected account in the Settings area. Then close the mail app, reopen it and add the account again via the settings.

      The Library folder is not usually visible, but if you go to Finder and then hold down the ALT key, this folder will also be visible in the menu.
      Before Catalina you could also find and delete the backups via iTunes, but I don't yet know exactly how it works with Catalina without iTunes. I guess I'll have to install the new macOS soon so that I can have a say. : D

        If you select the corresponding iDevice in the Finder in the sidebar for Catalina, then you will also find the backup function and a button “Manage backups” under the General tab. If you click on this, you can select and delete the backups.

      Hello julian! If the EFI is really damaged, then unfortunately only the Apple service partner can help. Do you have a backup to boot from? Alternatively, you may be able to plug the Mac Pro into the router using a LAN cable. Then you save the WiFi password entry and you may then be able to reinstall the system. I keep my fingers crossed! Please let me know if it worked.

    after installing Catalina the popup "Helpermcp" appears corrupting your computer. It's a good idea to move the object to the trash.
    But when you click on "put in the trash" nothing happens and the window pops up again. Likewise with "Cancel".
    In addition, the fan turns on continuously and time machine runs continuously.
    Is there any way to go back to the previous operating system?

    1. sir appleot

      Hello Karin! "Helpermcp" is a virus or a program that cannot be removed because it keeps starting itself and does not simply have to drag itself to the trash. The virus appears to be caught by the Mac Cleanup Pro malware, which masquerades as a system optimization tool. I would recommend you to check your system with "Malwarebytes" at the next opportunity. If your Mac doesn't start anymore, you can hold down CMD + R while restarting. Then you come into a recovery mode from which you can reinstall the system on another hard drive.

          Hello Karin! Thanks for the hint with the video. The fan may be related to an SSD conversion. But I don't know if your Mac has ever been rebuilt in this regard. If so, I recommend you my article on SSDFancontrol. Otherwise, you can look in the activity monitor to see what is generating the CPU load. Maybe something is still running in the background?

            Hello Karin! Time Machine may run for a while after an update to save all changes. I often leave my Mac on overnight so that it can do this kind of thing. I wouldn't worry too much about that.
            If you still have the feeling that something is going wrong, then I would delete the backup and start over with Time Machine. Then let it run for another night so that he can save everything and hopefully everything will be ok then.

    yes there are problems everywhere. But the fact that a major operating system update by Apple (the most highly endowed company on planet earth!) Does not even go through the installation after the beta phase, so that you have to reset the computer, is qualitatively a mockery of any description. :(

          3. Reinstall macOS over it

      Hello Margit! I had a similar problem. The Spotlight search didn't work for me for weeks and I tried everything possible. Ultimately, the following helped:
      1. Make a 1: 1 backup of the system hard drive on an external hard drive
      2. Boot from the external hard drive
      3. Erase the internal hard disk
      4. Use CarbonCopyCloner or SuperDuper to copy the system from the external disk back to the internal one
      5. Boot from the internal disk
      6. Give Spotlight a few hours to index and, if necessary, delete the index again

      I suppose this seemingly pointless copying resulted in a damaged file being skipped and then the Mac recreating it. Since then, my spotlight (and thus also the mail and calendar search) has been working properly again. Maybe it will help you too.

    One of the reasons why I switched from Windows to the Mac was the unspeakable problems that occurred after updating the operating system.
    In the meantime, unfortunately, Apple has caught up in this regard. Apple now also delivers its operating systems based on the banana principle (product matures with the user). I am struggling with this new Apple policy. In any case, Catalina is barely above the level of a final beta version at the moment.

    After switching to Catalina, I have the problem that I cannot connect to the Internet with the MBP. Neither via wlan, nor via network cable via usb-c and adapter.
    No problem beforehand. My IPhones and iPads, as well as a Windows computer, also work without problems in the wlan. Only the MBP with Catalina absolutely doesn’t want to go online anymore. Router is a FritzBox 7560 which I have already restarted.
    I'm slowly running out of Latin. Maybe you have an idea?

    1. sir appleot

      Hello Benny!
      Ok, that's weird. I was able to find similar problem descriptions and the following steps were recommended:
      1. Restart your Internet router and Mac
      2. Under System Settings> Network, delete the connections and create them again
      3. Under System Settings> Date and Time, check whether everything is correct
      4. Unplug all external USB devices
      5. Hold down the ALT key and click on the WLAN symbol in the menu bar and select "Create diagnostic report".
      6. Renew under System Settings > Network > Additional Options > TCP/IP > "DHCP Lease".
      7. Create a new network environment
      8. Delete / deactivate proxy or VPN connection

      If all else fails, you can still try to completely delete the network settings. To do this, go to this folder:
      Macintosh HD> Library> Preferences> System Configuration
      And there you throw these files in the trash:
      - com.apple.airport.preferences.plist
      - com.apple.network.identification.plist
      - NetworkInterfaces.plist
      - preferences.plist
      - Settings.plist

      And last tip: stop the mDNSResponder process. To do this, go into the Activity Monitor utility and look for the mDNSResponder process. Then mark the entry and click the X symbol in the top left. Technically, it seems odd that these things are related, but there have been a few instances where that has helped.

      Let's hope that afterwards your MBP wants to surf again: D

      Hello Achim! This can have various causes: for example an antivirus program or defective file permissions.

      If you like, you can boot into safe mode and then test again. If that doesn't help, I would boot in single-user mode (hold down CMD + S when starting). Then (if you can still read the script) enter the following: fsck -yf

      Attention, since the English keyboard layout is activated in single-user mode, you will probably have to press these keys: fsck ßzf

      Repeat the command until you see the message "The volume (name) appears to be OK". Then type "reboot" to restart the Mac.

      I hope that works. If not, I would set up the system from scratch and use the migration assistant to import the data from a previously made backup.

        I had already tried Safe-Mode, only helped to a limited extent, ie iMac shut down, then frozen again.
        Then I noticed that I had connected an external hard drive that I used to clone my drive and hadn't ejected it. Since the external disk was ejected and removed, everything has been running normally and the Mac is also shut down normally - can that be ???

        Then another question: How do you do a clean install since Catalina? I am referring to the two partitions “Macintosh HD” and “Macintosh HD - Data”. Wouldn't dare to go there at the moment.

          after weeks of testing I can report something new.

          For me, the shutdown problem is clearly due to the ejection of external hard drives.

          I have connected a WD hard drive that I use to back up TimeMachine.
          Ever since I ejected this hard drive before turning it off, the problem of freezing when turning off has not occurred.

          If I leave the external hard drive connected, it can be switched off - but quite often not either.

          So the problem is reproducible in my system.

Most of the time, it is because some old or defective Javascript is stuck in the cache, which prevents the page from functioning correctly every time it is accessed. Clearing the cache should help here.
      Alternatively, you can also try a "private window" in the browser. There is no cache used, if I remember correctly.

    2. In Safari, after a while of use, it is suddenly not possible to get to the web pages in tabs when clicking on Google search results. Entering a URL at the top of the address bar does not open a website either. In the attached tabs, I can move around without any problems. When this problem occurs, I can no longer open a page in Chrome, there I only see the gyro in the tab. It only helps to switch off the computer to fix the problem. Closing Safari and reopening it does not help.
    3. Password protected PDF files cannot be opened in "Preview". Entering the password and sending with return causes the preview window to freeze, I can't close the window either by clicking on the red dot in the upper left corner (point 3, same problem on 2017 iMac 27).

    Since I have to work a lot on the internet, the Safari problem is really annoying. Nothing about it can be found on the web.

      Hello Tom! I heard about these problems from you for the first time. I would probably stay on Mojave again until Apple releases 10.15.1. Did you take over your old data after the clean install? Or is everything still "clean"?

        Hello Sir,

        All my files are on iCloud, they are not saved locally at all. Only have 3 fonts installed that I need for my Pages documents (company). Actually only Roon Remote and a Brother scanner app as apps.

        After the clean install, I had the feeling that the computer was almost "slippery" thought, wow, that's a difference compared to the constant upgrading. Until the moment when I couldn't open a page again in the unpinned tabs in Safari ;-((

        I'll probably go back to Mojave tomorrow. The problems with Catalina remind me of the moment when I finally got fed up with Windows in 2014 and completely switched to Apple (and was actually satisfied with this decision to this day).

    Hello Sir,
    I also have the problem with turning off. Turning off the iMac "stands still". After that it restarts and I get the error message that the Mac was restarted because of a problem. The same happens with a restart. Now I have found that if I have uninstalled any program, switching off and restarting works without any problems.
    Is there a possible solution for this?

    Regards

      Hello Heiko! Do you mean: No matter which program you uninstall - afterwards it shuts down cleanly? And then only once? Or how should I understand that?

    I am going to sell my MacBook Pro. I don't need to use ICloud and the like. I'd rather go back to Linux or FreeBSD. Maybe even a Windows 10 is more likely than this broken MacOS - ultimately, the development was foreseeable for a long time.

      Hello Sir,
      yes, it is the same, no matter which program was uninstalled, then it shuts down cleanly. If I then continue to work normally, it does not shut down properly again.

        Hello Heiko! What do you use to "uninstall" the programs? Or do you just drag them from the Applications folder to the Trash?

    Even after the update to 10.15.1, Apple's "Mail" doesn't work for me! It loads thousands of new mails with no discernible progress.

    There are new emojis for that! Apple, great! :(

      I can now report that mail is running again for me! :)

      I had started 10.15.1 in "Safe Mode" [SHIFT] and then Mail had "cleaned up" the database quite quickly.

      Before that, I kept to the following problem solution:

          Roland,

          google "Mail not working in macOS Catalina, How-to fix". You will then find instructions on how to delete certain files.

          The mails are then re-imported.

    Update 10.15.1 - Apple "Mail" hangs and needs all resources (Activity Monitor CPU 123% !!!!).???????
    Does anyone else have this problem and maybe already solved it ?????

    Since the update, my iMac (2012) reboots after 2-5 minutes although no application is open and no abnormal activities can be observed in the activity display. Deleting NVPRAM and SMC did no good. Over-installation and hard drive check were also unsuccessful. Hardware test with 'D' does not work. Press Alt + 'D' to cancel with an error message. Does anyone else have this problem?

    I miss the "progress display" when synchronizing with the iPhone / iPad (the small rotating circle under "Places" on the left is not always displayed to me.
    This problem also occurs with the iOS update.
    I cannot see in which form the MAC is currently active or what is happening.

    Loss of the "Scan to computer" function on HP all-rounders in connection with the "HP Easy Scan" app, which also no longer really works.

    I am also one of those affected who have installed Catalina over a working Mojave, although the error only occurred to me after the update to 15.1.

    To check it I did a fresh installation of Catalina plus Update to 15.1 on a USB drive followed by the installation of the HP software for my Deskjet Pro 8720. And what can I say - everything works fine.

    I then did the same thing again with a virtual machine based on Catalina (VMWare Fusion) and now use that as a workaround, because this ScanToPC story is already very practical because of the possibility of combining different scans into a single PDF document.

    This is not so convenient with the basic drivers, such as those used by the "Digital Pictures" app.

    MacBook from 2016 fails to install at 34 minutes and brings up this message:

    Your computer restarted due to a problem. To continue, press a key or wait a few seconds
    This message is displayed in 5 different languages ​​and the Mac has been doing this for 3 hours.

      Hello Mirko! What's the question here? Did you restart the installation after the error? In rare cases, the installer is also damaged. Then maybe load it again. Just to rule it out.

    I have a MacBookPro 13 ″ from 2015 with 128GB. and had moved the iTunes library to an external hard drive.
    Is there a power to outsource the former iTunes libraries, i.e. music books and audio books, to an external hard drive?

      As far as I have read, this option is currently not available. macOS expects the media in exactly the same place in Library. Outsourcing with symlink doesn't seem to work with Catalina. But maybe there will be a solution for ...

      If you have outsourced your iTunes library, you can continue to use it as before, only via the Finder or via the individual apps. My media library folder is also on an external SSD because the internal one is limited in space. This also works under Catalina as it did under Mojave.

      1. BlueFalcon

        Hey, if you move your media library folder under Catalina, then of course you have to tell the various apps where to find it again. To do this, you have to hold down the "alt" key when opening the individual apps so that the window for searching and connecting the new storage space opens.
        As far as I know, however, all files must still be in a common folder in the conventional structure. So keep an eye out for the iTunes “Mediathek” folder.

        it is still there, that is correct, but it is moved to the individual libraries on the system hard drive. and used there and of course also processed. Unfortunately I don't know the path anymore because I'm back on Mojave. as long as that doesn't work

    Hello, I already updated to Catalina on my Macbook Pro early 2013 at the beginning of October and – fortunately – had no problems, now I have made the new 10.15.1 update and neither my Office programs, nor my Pages, Keynote or anything else work. I can't open old files, I can write new ones but then I can't save them. The message comes up that I can't save to the storage location: for example on the desktop "The file "Desktop" could not be opened"
    Is there already a solution for this? I have already clicked through some forums and found no help yet ...

    I have an iMac 2017. I installed Catalina there as soon as it was released. I knew that the 32-bit apps would no longer work, so there was no reason to complain. All other programs run amazingly well. Once they start walking. This means that it feels like an eternity before the programs are ready for use. Chrome takes about 2 minutes, the Office programs (including Outlook) a little over a minute, DevonThink just under a minute.
    My conclusion to Catalina: So far, no crashes or hangs, but overall behavior at the start of the program at a snail's pace. I suspect that a lot of apps and processes are loading in the background that I don't need at all. I can see these programs somewhere (but where ??) and deactivate them if necessary? Or to put it another way: How can I throw the unnecessary ballast overboard?

      So a minute or two before the program starts is of course extremely slow on a 2017 iMac. :( To clean up I would clean my mac x recommend. I've been using the software for months and haven't had a problem with it yet. You may have to look through things there under "Speed ​​> Optimization" and "Maintenance". Maybe some extension is slowing down the Mac. Otherwise, my recommendation would be to put the system on an external SSD if you don't have a Fusion Drive in your iMac yet.

        Oooh! I did the optimization and maintenance with CleanMyMac, but then something strange happened. Catalina restarted, I had to work my way through it like the initial install. And then came the shock. I had to reinitialize almost all programs like the first time. MS Office was no longer activated and a number of other things no longer worked. Okay, "never change a running system", but I just wanted to optimize the system. Everything is working fine now, but I won't be using Clean My Mac anytime soon.

    My MacBook Pro 2015 15 ', i7 with graphics card, has been at war since the update with MS Word.
    At first the program kept crashing (10+ times a day) and now my whole system crashes every time I mark more than 3 letters in Word or type too quickly.
    As a student who will soon have to hand in a term paper, it is pure horror! ¡

    Trying to solve this with an iPad for the time being cannot be more than a temporary solution.
    IT support at the university cannot help either.

    Please report if someone has a solution!

    PS have already reinstalled Word 3 times. All other programs work fine.

      Hello Colin! My "quick and painless" solution would be: Use Pages. At least it works and has everything you need for homework. In addition, it syncs with the iPad and you can work on iPad and MacBook Pro. I don't know what's wrong with Word. If you care a lot about Word, I would test a new user account under System Preferences > Users and reinstall Word there. Then you will know if it might be something in your other user account. Could be some settings files or something that are co
