AppZapper is a really easy to use Uninstall program.
As you know, uninstalling a program on the Mac is easy enough - just drag the application icon into the trash. But often you are left with preference files, caches, etc. AppZapper will find those for you too, and with a click of a button, move them all to the trash at once.
The shareware price is a deal at $12, but the software isn't perfect, and maybe you don't want to pay for something you could do yourself. You are allowed 5 free "zaps" as part of the demo. But an easy way to use AppZapper forever without paying is to let it find the files that need deleting, but instead of pressing "Zap!", just go delete them yourself. Then press "Cancel" until next time.
