I, too, have been a long time user of ccleaner for Mac, but the latest version won't launch on my computer (10.15.7). It sits in the dock but doesn't open. I use Onyx, instead. I tried iBoostUp for Mac, and found that it does what I can do manually without it. Also, all the reviews seem to be 6-9 years old, so I'm guessing not many new people are using it? As for the others you list, I don't want to pay for a cleaning tool.
