Basically, before I started using AppZapper for complete removal of the programs, I was just doing the drag'n'drop thing to the Trash when uninstalling programs. Now I do not wish to keep my MBP polluted with unnecessary cache and other "remnants" of the previous programs that might not have been removed completely by the drag & drop method. I've downloaded CleanApp, but from the looks of things it seems just like another AppZapper type of a program - for deleting current applications. However, I'd need something to look for possible remains of my previously installed programs. Is there such a program?
