Test: My experience with CleanMyMac 3 - is the system and disk cleaner for Mac worth it?

The hard drive cleaning tool CleanMyMac 3 in the test: I'll show you what the program can do and whether it's worth buying!

A few days ago I received the message that there is an offer of the system cleaning software CleanMyMac from MacPaw. Basically, I always cleaned up my Mac by hand and deleted old backups or the like when the hard disk space was a little tight again - and with an SSD drive it is somehow chronically too small. As a guideline, it is said that the system hard drive with an SSD should have at least 10-15% free spaceso that the system has enough space to "swap", that is, to swap large areas of memory onto the disk for a short time and use them again later. If you have less than 10% free memory, the Mac can always become sluggish because it has to work a lot more on the hard drive than necessary.

Update: CleanMyMac X - new version available!

Recently the new version of CleanMyMac came out: "CleanMyMac X". I have you here is a small contribution written about the new functions, but if you want to strike quickly, you will find it here in the shop still offer prices. I have this SetApp subscription and that includes CleanMyMac X - so no reason for me to have to buy quickly. ;-)

New from MacPaw: CleanMyMac X for the Apple Mac and its hard drive

New from MacPaw: CleanMyMac X for the Apple Mac and its hard drive

Previous solution: semi-automatic search and deletion

Up until now, the software "DaisyDisk" had always helped me to empty storage space. It scans the system for large folders and files and then graphically shows them quickly for the eye. The CleanMyMac 3 software sounded like a "more comprehensive" tool, as it not only locates large files, but also collects caches, system residues from old programs, mail attachments that are no longer used, data junk from iTunes and much more and offers them for deletion.

CleanMyMac 3 in the test: My fight against memory shortages

Clearly, I wanted to test the program on myself, because who could be a better test subject than me - since I've been fighting against insufficient hard drive space on my MacBook Pro 15 "for years. The tool also cleans up the system, to make the Mac faster overall, but I don't really have a problem with that, which is why my test is aimed more at disk cleanup.

After a short e-mail with the software company MacPaw, I was sent a license code for the full version - free of charge against the promise that I would write a test report. And I am only too happy to do that - but I also "warned" the marketing department that I would honest report who will definitely take a critical look at the software.

Der Preis for CleanMyMac 3 (CMM3)

Usually the license costs around 40 EUR; who has multiple macs with CleanMyMac 3 wants to equip, but gets good discounts. You can find the current prices here at MacPaw.

The menu: simple and clear

After the installation, the program is very clear. A menu on the left-hand side keeps the areas ready that can be scanned:

  • System remnants
  • Photo data leftovers
  • Mail attachments
  • iTunes junk data
  • Paper bins (yes, plural!)
  • Big & old files

Underneath there is an area "Utilities":

  • uninstall
  • Maintenance
  • Privacy Policy
  • Extensions
  • Annihilator

All points are explained again if you click on them once. You can find out, for example, that "system remnants" can remove temporary files or delete unused program code or unused languages ​​from the system without affecting the system's function. All other points are explained as well, but I will go into more detail about them later.

Smart-Scan: The button for acute memory shortages

What I have concealed so far: At the top of the menu there is a "Smart Scan" button. This enables a global scan to be triggered on the Mac, which includes all sub-items and "smart" only selects those files that are definitely no longer needed. Of course, I chose the button first. After a good 20 minutes, my entire MacBook with a 768 GB SSD hard drive was scanned and 44 GB (yes, actually!) Were found by Smart Scan and suggested for 1-click cleaning.

CleanMyMac 3 Smart Scan function

The CleanMyMac 3 "Smart Scan" function searches the system and the hard drive for files that are no longer needed and provide more hard drive space in no time with the delete button - a nice feature for acute emergencies or lazy people!

As you can see in the sidebar, even more files were found in the individual areas that could possibly be deleted, but these were not all selected because the user should keep an eye on this data if he does not want to keep it . The Smart Scan has already found a good chunk of potentially free hard disk space with 44 GB.

Of course, I didn't do that, because I wanted to test the other areas individually and not fix all the problems in one go. :)

The CleanMyMac Dashboard: The current status at a glance

At the top right of the CleanMyMac window there is a button called "Dashboard". This takes you to an overview that shows how much memory is occupied on the hard drive and what types of data (films, programs, music, etc.) it is occupied. The status of the battery in a MacBook and the utilization of RAM memory and processor are also displayed.

The CleanMyMac Dashboard shows current information about hard drive, RAM, battery and processor usage.

The CleanMyMac Dashboard shows current information about hard drive, RAM, battery and processor usage.

You can also get a mini view of this window by clicking the CleanMyMac icon in the menu bar. This gives you a quick overview of the utilization of the hard disk and the RAM.

The thing with the RAM ...

The RAM can also be released directly via the menu bar with CMM3, if you want. In my test, about 16 GB of 150 GB of RAM (all but 7 MB was occupied) were released again with one click. Personally, I think this function is superfluous, because OS X itself also releases RAM, but only when it is needed. So it is normal for the memory to be full after a long period of use. However, this has no negative, but positive effects: programs that are already open start faster the second time they are started.

Informative and easy to use

For laypersons in particular, it is important that programs are easy to use and that their functions are transparent. CleanMyMac is exemplary because every area in which you can search for deletable files is explained in detail. So you quickly know which data will be affected by the deletion and what effects this can have. If you want to know more, click on the small question mark symbol on the respective screen and you will then get to a (unfortunately English) description.

The division into different areas helps to target specific file types and media types. In this way, you can be sure, for example, that you only throw photos in the "Photo data leftovers" area and not emails. There are some other clean-upApps, who proceed very "comprehensively" and search the entire hard drive for all possible data - which they consider useless - and then delete all of it. For example, I would not recommend this type of "tidying up" app, since you can rarely decide in detail what is to be deleted and you also get little information about what the software actually classifies as "garbage" and what not.

With the Smart-Scan function of CleanMyMac 3 you have a comprehensive search and delete many file types at the push of a button, but here the app proceeds very "carefully" or "smart" and only deletes what really does not lead to any functional restrictions can. Private photos or mail attachments are not touched here.

Recycle bins: finally empty!

The "Recycle Bins" function of CMM3 is worth an extra paragraph for me, because not only the Finder-Trash emptied, but also those of the Photos and Mail apps. But what is a really good feature: With the function you can also get files from the recycle bin, which would otherwise always throw a Finder error message. I had serious problems with one of these a few months ago resistant files in the recycle bin and had to use an extra app for it before they were really gone. From now on, CleanMyMac will do it for me - and for you, if you want.

CleanMyMac 3 deletes undeletable files from the Recycle Bin.

CleanMyMac 3 also deletes "undeletable" files from the recycle bin, which otherwise always want to remain in the recycle bin with an error message via the Finder function "Empty recycle bin".

Hard drive storage: Great savings potential on every Mac

You may be wondering, but there is an enormous amount of hard drive space on every Mac that can be "freed up" by deleting files that are no longer needed. With my MacBook alone, it was over 768 GB on a 100 GB SSD hard drivethat I have with CleanMyMac could shovel free - and that although I have already thrown out larger files and folders with DaisyDisk here and there and have not let my recycle bin grow over 1 GB. Now you are probably wondering what can be saved there?

CMM3: iTunes garbage data - an area that offers a lot of potential for savings

The button "iTunes garbage" - an area in CMM3 that offers a lot of savings potential - in my case over 50 GB!

Without going into depth, I can give you a few points that CleanMyMac records and that will surely provide you with more free hard disk space:

  • iOS backups on iTunes: every time you connect your iPod, iPhone or iPad to the Mac, it is synchronized and a backup is made. Usually you don't need many of these backups, because either there are only a few days between the backups or there are even backups from old iOS devices that I no longer use. Even aborted backups only take up space and offer no added value. In my case they were good here 30 GBwho could get away.
  • iOS apps: Every app that you install on your iPod, iPhone or iPad is also backed up by iTunes on your Mac. If you then delete them from the iPhone, the app is by no means deleted from the Mac and, conversely, the apps do not disappear from the iOS device if you throw them in the trash on the Mac. So it is actually uselessly used storage space, because you can reload any app from the app store anyway - regardless of whether it is available in iTunes on the Mac or not. I threw everything out and that's fine 58 GB (!!!) shoveled freely.
  • System residues: This point includes all files that are not used on the respective Mac. These can be specific drivers, data for system languages, remnants of programs that have long been uninstalled and much more. Why do you need language files for Korean, for example, if you do not speak and use the language? If you delete this data, OS X will still work as usual, but you will have more free hard drive space. With me on OS X El Capitan, I was good at it 3 GB make free.
  • Large & old files: With this function, the user folder is scanned for files that have not been used for a long time and that take up a lot of space. You should of course look through the list, because just because it's a large file that has not been used for a long time doesn't mean you don't need it. Old films made by your children may not be watched very often, but they are large, seldom used and should NOT be thrown away. So watch out for the extinguishing! I looked at my list and I could 14 GB Clear.
  • Mail attachments: With every email that comes with an attachment, a file is saved on the Mac - namely the attachment. In the course of time, many files migrate there to the hard drive, which you look at once and then no longer need. For example, all the funny photos and films that friends send you for fun. This list is also very easy to go through with CleanMyMac and tick the files that you no longer need. CleanMyMac even lists files according to groups such as films, music, archives, images, etc. So you can quickly decide what is interesting and what is not. In my case they were here 3 GB Free space on the hard disk.
    Another note that I received after a query from the CMM3 team: Clean My Mac 3 deletes the email attachments on the computer. In other words, they actually disappear from the mail program. If you use an IMAP mailbox (as with most providers and also with me.com), you can later download the attachments from the server. So they are only deleted locally and not on the server!

You don't have to be a great math genius to see that we're already at over 100 GB of free hard drive space. This means that the load on my SSD is well below the limit of 90% full capacity and I don't need to worry about the space of my hard drive for a few weeks or months. :)

Utilities in CleanMyMac 3

As mentioned above, in addition to the various scan options, there is also a "Utilities" section. At first I didn't take a closer look at them, but the MacPaw team did a good job here too and set up a few practical tools, which I would like to present to you in detail here.

Uninstalling apps

You might think that to uninstall, you simply drag most Mac apps from the "Applications" folder to the trash, and that's all there is to it, but in practice there are always leftovers: files with settings, cache folders, and similar data gradually litter your Mac towards. The "Uninstall" tool in CMM3 gives you a list of all programs that are installed on the Mac. If you select a program here and delete it, you can immediately see in a list the linked files and folders that you might want to delete with or should delete.

CMM3 deinstallation of programs and program reset

CMM3 makes the deinstallation of programs and even a program reset (see red circle!) Very easy.

Program reset: Another great function in this tool called "Program Reset" is very practical and almost invisible. This function only deletes the settings data, but not the program itself. This often helps if programs crash with the message "Program XYZ terminated unexpectedly". It is not uncommon for it to depend on files that the program creates again after the reset if you delete them beforehand with "Program reset".


Under "Maintenance" you can repair access rights, delete the DNS cache, rebuild the mail database, run maintenance scripts from OS X or the Spotlight-Rebuild index. All things that can also be solved differently, but here they have been neatly collected in a list. Not absolutely necessary, but nice to have!

Privacy Policy

Here you can delete chat data from Skype and the Messages app, delete cookies, empty the browser history and delete other personal data that was created in browsers. This not only for Safari but also for all other browsers that are installed.

The "data protection" tool in CMM3 enables the targeted deletion of data in browsers, chat apps and in the Finder.

The "data protection" tool in CMM3 enables the targeted deletion of data in browsers, chat apps and in the Finder.


The "Extensions" area is very exciting, because here you will not only find extensions that are installed in the browsers, but also login objects that are started when the user logs in, finder plugins, start agents, system settings, programs and services Finder plugins. Often such scripts run unnoticed in the background and it is usually not easy to remove or uninstall them, as they are distributed in many different folders in the hidden library system folder. With this tool from CMM3 it is done with just a few mouse clicks.

The "Extensions" tool is the right place to go for a spring cleaning if you want to throw out background scripts.

The "Extensions" tool is the right place to go for a spring cleaning if you want to throw out background scripts.

While going through the list, I found a number of scripts that were running in the background and that I definitely no longer needed because I no longer use the programs. Even if it doesn't accelerate the system noticeably, it is certainly better for the stability of OS X if you only have the most essential things running here.


The "Shredder" tool safely deletes files without any error messages from the Finder.The "Destroyer" tool is relatively unspectacular - even if it has a martial name: it safely deletes files. This means that the file is overwritten several times with zeros so that it can no longer be restored - even with special data recovery tools.

The tool can also be used to delete files that would otherwise give rise to error messages in the Finder. For example, you can delete data that the system is somehow still using.

My conclusion on CleanMyMac 3

As you might have seen from the previous article, I am very enthusiastic about the Mac app. I think it is especially recommended for people who often struggle with a full hard drive or who can install and uninstall many programs and keep the system clean with CleanMyMac.

Anyone who has an iMac with a 2 TB hard drive and just surfs the web a bit and emails or takes a few documents with them Numbers and Pages, he probably doesn't need CleanMyMac, because he will hardly reach the limits of his Mac - neither in terms of processor performance nor hard disk space. But if you – like me – use many different programs with high requirements (Adobe Photoshop, 3D rendering, video editing and the like) on the Mac and maybe also work on a MacBook that is always borderline full anyway, CleanMyMac should be a reliable and have found a very good all-round tidying-up program.

Some file types, such as aborted iPhone backups, browser caches, old mail attachments and the like, can also be found by hand if necessary and can be deleted - but I don't have a Mac to spend hours in some folder structure. With CleanMyMac it is so much more elegant: One click on the "iTunes garbage" area, one click on "Scan" and after a minute I get a list in which even the backups that are old or canceled are preselected. The last backups of the respective iOS devices are not automatically selected by CleanMyMac 3 - this shows that the Mac app is actually "smart"!

I can only recommend the Mac app, and I'm sure I use it a lot to clean up my MacBook Pro.

    i even bought the bundle clean my mac. not cheap, but very good. got 60 gb free from my hard drive.
    thanks for the tip, was timely and very helpful!

  2. Odette Hamberger says:

    I read with great interest because I don't understand a lot about my Mac Book Pro, but I would like to play. I took the test and I will buy this program in the near future. I thank Sir Apfelot for taking the trouble.

  3. James says:

    Thank you for the comprehensive and still manageable evaluation, that is, to be remembered, which reassures me that these programs unfortunately often lead to the cost trap as decoy demo version and then do not really keep what they promise.

    • sir appleot says:

      Hi james! Yes, I know these programs too ... most "system optimizers" should be used with caution, but CleanMyMac really did something programmed with hand and foot. If you use the default settings, only files appear that you can dispose of without worry because they are really no longer needed. If you go to the trouble and then go through the rest of the files yourself, you can indeed save even more space. But that's more for people who know what they're deleting. But thanks to the smart setting, it is really very good and risk-free to use even for beginners. And it does indeed bring something ... in contrast to some software that "cleans" some dubious things and then, in the best case, leaves the Mac as it found it. ;-)

  4. Gerhard Schaich says:

    I can certainly clean up multiple accounts on my iMac or do I need a multiple license.
    Can my iPad, Macbook be cleaned with it?

    I think that the program will give you a better overview of the data. I hope so, anyway.


    • sir appleot says:

      Hello Goschy!

      The software does not work on the iPad and iPhone. It is made for iMacs, MacBooks, Mac Minis or PowerMacs. And you can also use the software on your iMac and MacBook - with one license. Just not at the same time. ;-) But that's not necessary either ...

      • Hans says:

        hello, sure that you can get by with one license on a Mac Mini and a MacBook?
        but then the software may not run in the background, for example, when the other is being scanned, right?
        I just got the trial version and wanted to buy one.

        • sir appleot says:

          Hello Hans!
          So you can't quickly switch back and forth between two Macs. When you activate a license, the other machine is deactivated (I assume), but it is also possible that the providers of CleanMyMac have come up with something else. As a rule, however, they would have to allow a computer change, because everyone will get a new Mac at some point. ;)
          In your case, I would just buy the 2-Mac license for 59,95 EUR ... then you have peace of mind and save yourself the pain of switching back and forth ... LG and have a happy new year! Jens

  5. Jürgen says:

    How long is the license valid? Do you have to buy Clean My Mac 3 every year?

    • sir appleot says:

      No, this is not an annual subscription or something similar. The license is permanent. You may have to do an update at some point when there is a new macOS, but Clean My Mac 3 has also been updated free of charge for macOS Sierra, so you don't have to worry that a new Clean My Mac would be necessary.

  6. Heinz says:

    I am ready to delete CleanMyMac 3 again, because this tool has now simply "eliminated" my iPhoto albums from the last 2 years for the second time, which is inexplicable to me. In both cases I had to replace and repair iPhoto using TimeMachine.

    • sir appleot says:

      Hello Heinz! That doesn't sound good ... have you ever reported this bug to support? I've done the auto-clean several times, but so far he's left my photos alone. Actually, the auto or smart function is programmed quite carefully, so that only things are deleted that are definitely unnecessary.

      • Hello Sir Apfelot, I reported this bug to support using the contact form - but have not yet received an answer. Of course, I would have to ask Apple too, but I'm afraid they'll tell me it's because of CMM 3.

  7. Wolfgang Mouse says:

    Dear Sir Apfelot, have you been knighted by Apple or are you an Applian? Soon there will be a question from the mouse knight who is hoping for a good answer from you!

    • sir appleot says:

      Hello Wolfgang! No, so far Apple hasn't done anything to me ... neither knighted nor beaten together. ;-) But if you have a question: Just give it to me! Often I also have to pass when it comes to things that I don't do anything with myself, but I try to give my half-knowledge to the best! : D

  8. Bernstein says:

    Good morning,
    I am now suggested "maintenance" of my Mac every week, how often should this take place? Not that I don't have any more afterwards :).

    • sir appleot says:

      Hello Amber! So basically the program doesn't delete anything that you might need when you run the SmartScan. This affects more files like caches and the like, which gradually accumulates. And if this is too often for you every week, you can set it to every 4 weeks or so under "Settings -> Schedule". I have it with me every two weeks and every four to eight weeks I look through the "Large and old files" section. You'll get a lot with that. I hope I could help you with it!

  9. Sara says:

    Thanks for the contribution! After some initial uncertainties, I decided to use the program :-)

    Cheers Sara

    • sir appleot says:

      Hi Sara! I am pleased. It is one of the few "cleanup programs" in the world that I can really recommend. There are people who completely advise against such programs because they would be useless as macOS would do all the cleaning itself, but this is not the case in practice. CleanMyMac removes things that macOS doesn't delete on its own. So good luck with cleaning up! : D

  10. Georgian says:

    Hello - I've been using CMM for many years.
    Why is it generally not recommended by "Apple specialists"?

    • sir appleot says:

      I think the "specialists" don't take the time to actually test the individual tools. There are a few cleanup tools like this one that has "Keeper" in its name. It installs itself deep in the system and you can hardly get rid of it. You do massive advertising with means that I consider more than questionable. You have probably already seen these warning windows on websites that want to let you know that your Mac is currently having X problems. Then there's a "Repair" button or something and that's how you catch inexperienced Mac users. I would also trust this tool to collect user data during the analysis and send it home.

      Clean My Mac, on the other hand, is equipped with an uninstaller that cleans the program from the hard drive if you don't want it. The analyzes are comprehensible and so far I have not had a single case in which something was deleted from the disk that I still needed.

      The specialists simply rely on the capabilities of macOS, which already has cleaning routines, but a number of things are also ignored, such as unfinished downloads from the AppStore, unused language files of the system, old backups of devices that are no longer in use , etc. To this day, macOS still does not have a function with which you can "uninstall" programs correctly. Here, too, CMM offers a lot of convenience in that it suggests files for the selected program that you can delete in addition to the main program if you want (drivers, caches, settings etc.)

      I think that as a "specialist" one shouldn't generally advise against cleaning tools, but rather differentiate why one would not recommend one or the other program.

  11. Manfred Bachle says:

    Hello, good morning,
    I have a 10 year old MacBook, version: Mac OS X, 10.6.8, it has become very slow and more and more
    Internet addresses refuse to cooperate with the reference to my outdated browser
    "Clean my Mac" program from Mac Paw is also suitable for this version, still substantial improvements
    The Apple dealer Gravis explained to me that the Mac Book mentioned was no longer software-related
    is supported.
    Who can give me a good tip?

    Manfred Bachle

    • sir appleot says:

      Hello Manfred! Maybe you can install a newer version of macOS. But I would have to know which MacBook you have exactly. Can you click on "About this Mac" in the top left of the Apple menu and then send me the first line where it says "MacBook ..."? I can tell which model you have.

      Basically, Clean My Mac does not help if your browser throws warning messages. This usually happens with SSL-encrypted websites (banks, etc.), which for security reasons only want to allow you to access the pages with the latest browser. But if you should buy a license now, you can use it again on your next Mac. So it wouldn't be wasted money trying to clear out your MacBook.

  12. Just tried installing CleanMyMac 3 for me. During the first process: clearing caches, he hung himself. Searching for the content to be deleted still went perfectly, but with the real deletion it came to the User Cache file (first action of many) ... WebKitCache and at the bottom CleanMyMac showed: "remaining 4,2 GB". That doesn't change for 7 minutes. That's when I stopped CleanMyMac. He told me what he (supposedly) deleted and asks me to buy the license.
    Well, if the trial version already fails, then I won't buy a license, but will uninstall CleanMyMac again immediately.

    • sir appleot says:

      Hello Herbert! Sounds like he hung himself up somehow. I haven't had a problem with the program in ages. But if I were you, I would ask support. I contacted them about a couple of questions for this article and they responded quickly. And they weren't standard answers either, they were helpful things from someone who also has a clue. So there's a good chance they can help you with your problem too. At least I think so. ;)

  13. Christian says:

    The program has been known as scareware in Mac circles for years (successor to MacKeeper!) And is partially recognized by malware scanners (including MalwareBytes).

    You are doing nothing here but paid advertising and this is still quite naive - a little Googling would have helped to get really smart about the software.

    • sir appleot says:

      Hello Christian! I take note of your assessment, but for various reasons I cannot share it and I also have no guilty conscience about recommending Clean My Mac to others, as it helps me to clean the SSD or any remnants of software every few days to remove, which I always install for test purposes. But to your objections:

      1. From my point of view, MacKeeper is a tool that should be used with caution. Apparently it is difficult to uninstall and the manufacturers do massive advertising, which I also find dubious. So we agree on this, but I'm still thinking about taking a closer look at this tool before I write about it in a pejorative way.

      2. Clean my Mac is the successor to MacKeeper? I cannot understand this statement. Do you have any sources for this that are reputable and not just any forum posts that any troll might as well have written? A point that speaks against your theory: In the masthead of MacKeeper is the "Kromtech Alliance", which has offices in various countries, and in the masthead of Clean My Mac is "MacPaw", which is based in the USA / California. Apart from that, both programs are currently available and more like two competitors than "predecessor" and "successor".

      3. Is Clean My Mac known as "scareware"? Here too I would like to contradict you. If you read up what the term "scareware" means (here at Wikipedia for example) then you will find that this type of software tries to give people messages like "You have 21 serious problems on your computer!" tries to fool a problem that doesn't exist. Everyone knows the corresponding popups on the Windows PC. ;-) Clean My Mac does not report such things and does not advertise them. It only offers to clean up the Mac and help when mam wants to uninstall programs or remove certain startup software or system extensions. And from my point of view it does that reliably and seriously.

      4. I do paid advertising? No, I recommend software that I use myself, have tried and find good. It is a nice side effect that I can use an affiliate link to support my blog a little, but whoever reads my posts knows that I only present things that I can recommend with a clear conscience. I have already criticized a number of products and I am also happy to have this freedom and not have to rely on advertising income from manufacturers. If I've tried MacKeeper and think it's as bad as many others out there, I'll write it openly - even if they promise me commissions on sales.

      5. Should I google it to find out about the software? Yes, there are numerous threads in forums about Clean My Mac and other tools such as Onyx etc. There are always two camps: Some think such tools are totally pointless because the Mac does everything on its own and others think the tools are good . And as with all forums, every Horst-his-brother speaks up and gives his mustard. In the end, you know as much as you did before when you've struggled through all the posts. I want to add some added value and try the program BEFORE I downgrade it. It is true that you don't need all of these cleanup programs because you can do everything by hand. But I have an SSD and therefore little hard drive space and I can't spend half a day every 4 weeks to fish any interrupted iPhone backups or the like out of the system and toss them into the trash. I prefer to work in the time and let Clean My Mac do this work. And so far (for over 1,5 years) I haven't had a single problem with the program. It does its job and clears 5-10 GB from my SSD hard drive every few weeks. I can use it to quickly activate and deactivate system extensions and launch agents. Why should I do it badly like others do who have not even used it (and I assume you and others now) have not used it ?!

      I wouldn't come out as a serious blogger if I just hit the notches that others have already suggested ... I'd rather accept critical comments like yours (thanks for that (without irony!)) And address the points, thrown into the ring.

      I hope this comment has helped and cleared the confusion a little. It also motivates me to give programs like MacKeeper and the like - which I feel I would not install - a chance and think outside the box ... I think there are few factual and emotionless reviews about it. Maybe I can deliver one - after backing up my hard drive! ;-)

      LG! sir appleot

          Thanks for the link. I read it through, but I don't understand what information I should pull out. What is there is for me partly quite meaningless. Example "CleanMyMac is not allowed in the Apple App store, because it is not safe." This is nonsense, because it is not in the AppStore because the program would not serve its purpose if it implemented the necessary sandboxing for the App Store. This is the case with many app developers, which is why you cannot find a number of reputable programs in the app store, for example. It has nothing to do with "safe" ... but maybe you wanted to tell me something completely different. VG! Jens

            And where is the source for your statement?

            Other system tools are well represented in the App Store, so please bring facts instead of guesswork.

            CleanMyMac has been proven to interfere with the network functions of WLAN (with WPA 2 Enterprise) and VPN software (Pulse Secure) - in both cases the problems are gone as soon as CleanMyMac is uninstalled, the "tool" is at least suitable for this. ;-)

            Ultimately, I don't want to mislead you into speculation and guesswork, but the way you speak of the specialists in your statements is disrespectful - they may have more (professional) experience and can also manage your system well manually and know what they are doing - and maybe that's why they advise against * this * tool because they have tested it. had to fix the effects of it.

            When I read that you have accumulated 100 GB of "garbage" or that you were unable to delete files from the trash (e.g. because you are not familiar with the terminal or have found free tools for it), then I doubt that you can System specialist.

          • sir appleot says:

            I don't doubt that you have more knowledge of networking and other things. Maybe you are a "system specialist", but I think I have a better view of "normal users" because I am exactly one of them. I tried to get rid of the non-erasable files with the terminal and I also know the "rm" command in the terminal. But in the end it didn't work. No matter where the error was: For me as a Mac user who likes Klickibunti programs, what ultimately counts is which program solves my problems.

            I certainly do not present myself as a system specialist anywhere in the blog. With my blog, I only want to help people who have exactly such everyday problems as I do and who are NOT system specialists. I already know that they might prefer to delete some caches with the terminal, but programs like Clean My Mac are not intended for them either.

            And in the app store you won't find an Onyx, for example, if that counts as an example for other system tools that don't do anything bad and are still not in the app store. Even the color selection tool "Sip", which really doesn't do anything that could damage any files, was taken out of the app store by the developers because of sandboxing.

            I can't say much about the incompatibility that I mentioned, but it might be helpful for users who have problems with it. I also think it's nice that you are taking the time to voice your concerns here. I think our discussion makes both sides of the coin clear again. Good night to you I'll hit it. : D

    Dear Sir Apfelot,

    I really liked your factual response to all contributions .. !!!

    good luck for the future and thank you very much, Wilfried

  15. Richie says:

    Thank you very much for your detailed description!

  16. Adrian says:

    I am extremely grateful and would like to clearly recommend this software. Had problems with "resistant" files in the recycle bin for a long time. CleanMyMac has been plowing for two hours, but my system is now really fine, the recycle bin empty and 10 GB recovered.
    Greeting! Adrian

    • sir appleot says:

      Hello Adrian! Nice that she helps you. I'm all too familiar with the trash can. But has CleanMyMac worked on it for 2 hours ?! My goodness! : D You probably had hazardous waste in there. ;-) LG and have a nice Christmas time!

  17. Thessie says:

    Hello, are the costs for the "CLEANER" calculated monthly or annually?

    • sir appleot says:

      Hello Thessie! As far as I know, they have abandoned the subscription model and are offering the program at a one-time price. Alternatively, you can also use it Setapp to get. I have booked this software subscription and am always happy to see what good programs are included there.

  18. Adrian says:

    Dear Jens
    After a long time, another topic about Clean MyMac. I updated my Macs to Catalina and accepted the disadvantages. One of them: I also had to buy the new version of the Clean My Mac. (Incidentally, I like your balanced, stress-free and error-free language in discussions like here.) - One question: When a program is started, the CMM keeps responding in a rather cheeky way with reference to non-responding programs: “CMM enables you to use applications that have hung up have to end immediately or wait until they react again. " Apart from this wording, which is not exactly ingenious for me, this message bothers me and I wonder whether this MCC should not be switched off in between. As a tool with the functions you have also described, this is certainly a great thing, but more of a troublemaker when starting programs. As Macians, we know the launch issue.
    Nice and sunny autumn greetings from Zurich,

    • Jen Kleinholz says:

      Hello Adrian! Thank you for your praise. Because of your question: Yes, I was pissed off too. The funny thing is, you can turn off the messages yourself with CleanMyMac X. To do this, go to the Optimization> Login Items area in CMM and you will find two files that have CleanMyMac X in their name. If you deactivate both of these, CMM will no longer run in the background and accordingly no more annoying messages will appear. Maybe this can be done somehow via the settings, but I like to choose the complete removal. The less tinkering in the background, the better for the stability of the system. LG, Jens

    So, I would like to briefly leave my mustard here for CleanMyMac
    since there is little criticism to be found here.
    The chat seems more like a sales talk led by Mr. Kleinholz,
    which is intended to promote the sales of the program.
    I see it as pure moneymaking.
    My Mac crashed up to 5 times a day with this program.
    The computer became slower, etc.
    The best happening on the program:
    After it was recognized that the software acted as a disruptive factor, uninstall it again as soon as possible, then the system runs smoothly again!
    So: go for it!

    • Jen Kleinholz says:

      Tach Ben! I take note of your opinion and as you can see, I am not filtering any comments that are of a critical nature. Unfortunately, there is no chat here in the blog, so I cannot understand what you criticize about it or what is supposed to be a fake sales pitch. But OK. Your Mac may have crashed 5 times a day because of this program. However, there are also Macs that crash due to antivirus software if there is the wrong constellation between installed apps and the wrong system. From my point of view, this is no reason to deny a program its right to exist. I think - even if I'm not a big fan of antivirus software - there are definitely users for whom such software makes sense.
      I've run CleanMyMac for years and keep using it, and so far I haven't had a single crash that I could blame for this program. But if it caused you to crash, it's probably better not to use it anymore. I know numerous readers who have no problem with the program and who enjoy using it. And for information: my system runs smoothly, among other things, because I can use the program to throw out start agents and the like without having to read through long instructions.
