If not CleanMyMac, what other options ?

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners, Bit Torrent, or a VPN that you installed yourself. The main reason is that they are relentless in scanning your files, non-stop, looking for virus-like patterns in Everything, or looking for files that have changed. When completed, they do it all again.

The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect or speed up your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.

 You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.

Your exceptionally well-crafted Macintosh computer does not accumulate filth that needs any third-party anything to clean it. Everything needed to run it efficiently was included in the box, except ONE: a drive on which to store a second copy of your files in case the first copy is damaged or deleted by accident. The backup software, Time Machine, is already present -- integrated deeply into MacOS.

Your Mac will clean itself on its own. There are 4 categories of apps that should not be installed:

• Cleaners
• Optimizers
• AntiVirus
• VPN

In addition, if you add any app that has an installer, then you must remove that app with the uninstaller that should be supplied with the software. With any modern app, using an Installer to add the software is unnecessary and should be avoided if you can. When an installer is not used, you can simply move the app to the trash to delete the files associated with it.

Apple uses its Software Update service— as a mechanism for installing “background and critical” updates that are installed silently in the background with no notifications to the user.

The macOS has featured elegant and automated self-maintenance routines for 24 years. Catlike, Macs clean themselves. These routines handle ALL required housekeeping, including defragging, and need no help from scammy third-party products.

On the other hand, if you want to party like it's 1995 all over again, useless third-party "maintanance" utilities can help you there.

No such product is required for your Mac. Instead, please read: Effective defenses against malware and ot… - Apple Community
