Avoid Any Mac “Cleaning” Apps
Hey , Just a quick warning to anyone thinking about installing apps like CleanMyMac I strongly advise against it. After using it once, my Mac started having serious performance issues that didn’t go away even after a full erase and reinstall of macOS. I even went to an Apple Store and they couldn’t find any hardware issue or explain what caused it. So honestly, Avoid these kinds of bogus apps they create more problems than they solve.
