CleanMyMac is a legit app.

I wouldn't call it safe unless you consider the indiscriminate deletion of files from your Mac as being safe.


CMM is in a class of apps that are unnecessary and unneeded on the Mac.


These would be cleaning, optimizing, security, anti-virus and VPN softwares. All unnecessary and very often causing more problems than they purport to prevent because they conflict with the macOS’ built in securities. If you have this type of app installed, you should uninstall it according to the developer's instructions, and use best practices when using your Mac.


If you want to keep your Mac secure, follow this guidance:

  • Keep your macOS and other software up to date.
  • • Don’t click links in email.
  • • Don’t download apps from unknown websites.
  • • Don’t disable your Mac’s built in security.

Apple’s App Store search algorithms are known to be opaque black boxes. But CleanMyMac is pretty obvious. It’s one of the more ubiquitous apps, right up there with Chrome, Photoshop, and Word. And it’s not difficult to see how that happened. They’ve painted the internet in ads.


Apple is certainly willing to go up against other major app vendors on iOS, but not the Mac.

I can't speak to just how apps earn featured placement like that in the App Store, but I have suspicions.


How does it make any sense that when I search for "macOS" (just that term, not a particular version), this comes up? Not the "Story" about all of the different macOS versions available via Software Update or via the App Store, but this:

I think there is one that says that your app is useful but you cannot say that it's useless since it can still give you like ram and storage usage (Ik there is a menu bar thing that can give good info) or can even help to find old files...


So that's why it's there... but if your goal is too clean cache and such stuff, it's just useless...
