Chapter in this post:
With macOS 10.14 Mojave, Apple recently released the latest operating system for the Apple Mac, Apple iMac and Apple MacBook (Air / Pro). Upgrading from older versions such as macOS 10.13 High Sierra to Mojave can be done free of charge via the App Store if you are connected to the Internet. But no system is perfect, especially not at release. The first macOS Mojave problems keep popping up here and there - from the installation and various settings to the lack of compatibility of individual apps. Which Mojave problems there are and which solution is known in each case, I have compiled for you here.
Every macOS has teething problems. Some are due to system functions that have not been 100% checked in advance, others are caused by app developers because they do not provide their software with a compatibility update directly. Below you will find currently known macOS Mojave problems and - if they can be found - the corresponding solution. Since I could not adjust everything as specified and edit it myself, this time I give no guarantee or guarantee that the measures shown will be successful. If you had success with a macOS Mojave problem solution listed here or a measure you found yourself, please leave a comment;)
In the first few days, in particular, there were repeated reports that the macOS Mojave download was aborting for some users, would not start or would become an ordeal due to error messages. If the download aborts or you cannot even start it, this can have several causes. Sometimes a macOS Mojave download error message already indicates this - sometimes it is rather cryptic: “The installation of macOS could not be continued. The installation requires important content. This content could not be downloaded. Try again later. "- one way or another ...
Possible causes and solutions are:
Did the download and save work, but having problems installing macOS Mojave? Then, if you haven't already, check the list of compatible Mac models linked above to see if your device is made for Mojave at all. If the Mac is compatible, but the installation does not start, look for the installation file in the Applications folder, double-click it and start the Mojave installation manually.
If you still have macOS Mojave installation problems, look for a working solution here:
If you want to equip a Mac, an iMac or a MacBook without an internet connection with macOS Mojave - i.e. with an external hard drive, a USB stick or an installation DVD, this can work; but does not have to. There are already some reports that there are problems with the Mojave upgrade from external storage media.
Here are the few solutions that can be found on the web:
It can also happen that downloading and installing macOS 10.14 works great, but the Mac does not start up afterwards. There is still no need to panic. Because there are solutions for this too - for example the Reset of NVRAM and PRAM. In short, it can work like this to get your Mac up and running again:
So, now the download and installation of Mojave worked - and the Mac boots as it should. Now it comes to the system and its problems or dropouts. For example, some users report that Bluetooth is not working. If a Bluetooth connection is also not possible on your Mojave computer, then this procedure is supposed to help:
Everything went really well, and the Mac starts and runs too - just much slower than before? Here, too, there are various possible causes as well as appropriate solutions. So if your macOS Mojave problem consists of a slow Mac, then choose something here:
Everything okay with the download, installation, boot process and Mac speed? Then try out the individual Mac apps that you have installed. Older software in particular is prone to macOS upgrades and could fail on the new Apple operating system. If you find an app that no longer works under macOS 10.14 Mojave, look in the App Store or on the provider's website for an updated version.
If there is no Mojave update for your app version, then you have three options to choose from: buy a newer version, look for an alternative or downgrade to the old system (High Sierra, Sierra, etc.). This also applies in the event that the programs in question are 32-bit apps; because Mojave prefers 64-bit apps.
After my update to macOS Mojave, I started the banking app MoneyMoney (highly recommended!) For the first time. This was acknowledged with an error message stating that the MoneyMoney application file is corrupted and that I need to reinstall the app.
I actually thought I had always made all the updates, but apparently I had missed the last one, because after the reinstallation with the download from the MoneyMoney website, everything went back to normal.
Another Mojave problem can be that the iCloud synchronization does not work or does not work properly. As a first approach, you should follow the old plug-out-plug-in principle. So log out of iCloud and then log in again. To do this, choose the -Menu out and in the System Settings. Click on iCloud and then at the bottom left Log out. Then sign up again.
If that doesn't help, you can also delete the folder with your iCloud data from the hard drive (after a corresponding backup). The Mac then searches for this data or for updates to it and consequently has to re-establish the iCloud connection. But before that you can also try a third solution.
This consists of ending processes that are important for iCloud and synchronization. Because the processes have to be restarted and iCloud has to be rebooted. In the Activity indicator under the rider CPU you search for "cloudd" and terminate the process; then you do the same with the process "bird". Then restart the Mac if necessary.
Other messages about macOS Mojave issues concern the battery of MacBook, MacBook Air, and MacBook Pro. If the battery life drops rapidly after the system upgrade, then it is important to identify the cause. You can use the activity display again:
Updating them can also help against high energy consumption by apps. If there is no Mojave update for the apps, then look for alternatives if necessary. In any case, closing the programs promises short-term success so that the battery is relieved.
If you have a 27-inch iMac from 2012 with a TB of storage and are using Boot Camp, then you should either reconsider this or the Mojave upgrade. As Apple already wrote in its own support document (HT209057), macOS 10.14 cannot be installed on this iMac model with a 3TB hard drive - at least not as long as there is a Boot Camp partition. The operating system can only be updated once this has been resolved.
I haven't seen any major problems using macOS 10.14 Mojave so far. I only noticed one strange thing: the search field integrated in Firefox suddenly has white text on a white background. That is irritating, but of course no reason to speak of a faulty system or an incompatible app: D
Update 28.09.2018/XNUMX/XNUMX: The solution to the white font color was fixed with the change to the "light theme" and a restart. Obviously the white font color was triggered by my choice of the dark macOS theme. I think there are still problems between macOS Mojave and individual apps that have to be straightened out gradually.
If you are still about to upgrade your macOS and use this guide to prepare yourself for possible Mojave problems and to sound out solutions in advance, here's another tip: Make a backup before upgrading the Mac operating system - at best a bootable backup where you can install your old macOS version and continue to use it as usual. In addition to Apple's own solutions for data and system backup, you can also use the apps Carbon Copy Cloner and SuperDuper! use. A comparison of both programs can be found with this link.
I think readers have mostly reported that their HP printers have stopped working. Of course, this does not apply to everyone, but old printers in particular seem to have a problem with macOS Mojave.
The solution to start here is:
This should get most printers working again.
From my reader Hans-Ulrich, I got the feedback that printing via AirPrint from the iPad or iPhone still does not cause any problems. He has the HP OfficeJet 8600.
