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

iPad Pro, iPadOS 16

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.
