Is Clean My Mac a recommended program?

I ask as I've had my 27" iMac, that is up to date re system software, go to a black screen with a ? in the lower hemisphere. This has happened twice in the past week. I have run Apple Diagnostics but No Issues was reported. When searching online, there was a recommendation to in stall and run Clean My Mac. thanks

I've been using CMM for almost 10 years. Please convenience me otherwise. Is "System Junk" a scam? How else will we clean out User Cache Files (sometimes over 5GB in size) taking up HD space. Does Apple remove this for us? If so, when? Also what about System Cache Files that keep accumulating overtime that can be gigs in size. Should we just let these extra files that clutter and accumulate? Is there a use for them?


Can the Apple OS find large files that you hardly ever use?

If I don't clear 112GB of purgable space on my HD, will it clear on it's own?


Please enlighten me.

Interestingly CleanMyMac is sold in the Apple App Store. I cannot say whether it is a good or bad thing to run but I have been using it for about seven years with no issue. One time it supposedly found a couple of infected files on email attachments that were in the Junk inbox. The comments here make me wonder if I should delete but since I have never had an issue it gives me pause.

Most experienced users on these forums consider CMM as malware. NEVER EVER install third party:


  1. Antivirus apps
  2. Cleaning apps
  3. Security apps
  4. VPN apps


Unless you want your computer to become unstable, slow and make Mac OS appear buggy. To keep your Mac running well simply keep Mac OS up-to-date and restart the computer about once every week or so.

No, do not install CleanMyMac.


The black screen with ? means that your iMac could for "some reason" not find the startup disk.

"some reasons" can be anything from an incomplete update to a flaky external hard drive.


If the black screen reappears randomly, regularly or you can not move past it.

Mean time, I would startup in Safe Mode followed by a normal restart.

Clean my Mac X is a recommended platform by many users. It might help.

CleanMyMac is NOT recommended in these forums due to the number of problems users have experienced when they have installed the software. Don't take my word for it, just click the search tab on the top of the page and enter "CleanMyMac". Experienced users recognize it simply as Malware. The app can be downloaded for free, but will give you fake alerts that require a paid subscription to remove. Inexperienced user just think that the program is working by solving these fake problems, but if they never installed it, they would not have any problems that would require the subscription to fix.

Do not install CleanMyMac. You will be back here after it causes more problems with your computer. In addition, you will be back needing help in how to delete it, as it will do its best to remain on your computer causing popups with fake problems so you will download another program for the supposed fix.


We are here to help with the current issue you are experiencing. You may want to include a screenshot of what you are seeing and any more information on when you are experiencing this behavior. Does it seem to happen after a set amount of inactivity when a screensaver should be starting?

CMM meets the minimum requirements for selling thru the App Store and Apple is in it for the $$$. If you do a search of the Ventura, and earlier system communities you'll find hundreds and hundreds of posts where CMM was the culprit for the problem cited.


It's your calla but none of the experiences contributors here will recommend CMM nor let it anywhere near their Macs.

Just from this thread, there's a lot of good advice to not use CleanMyMac.


Your Mac will take care of all the maintenance. No third-party utilities are needed for this and they do more harm than any good.

It may not be designed as malware but it's so poorly designed that it looks for items that can't be there, gives false positives, moves files it shouldn't touch which messes up the system and apps.


Apple lets it on the App Store because it brings in revenue. It's simple as that.


The only app that is designed to look for and isolate malware that I can recommend is the free version of Malwarebytes. It was developed by a long time contributor to these forums and a highly respected member of the computer security community who knows Macs.

After uninstalling according to the developer's instructions Yyou can check to see if you've removed all of the supporting files by downloading and running the shareware app Find Any File to search for any files with the application's or the developer's name in the file name.  For the CMM software you'd do the following search(es): 


1 - Name contains cleanmymac

2 - Name contains macpaw


Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.


FAF can search areas that Spotlight can't like invisible folders, system folders and packages.  


If you get warnings that the file can't be deleted because it is in use or used by another app boot into Safe Mode according to How to use safe mode on your Mac and delete from there.


Note:  if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode.  This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.
