Quick question for some more advanced users... I've been toying with a lot of applications for my macbook lately, and I have found some real winners. Unfortunately, I found even more losers. I delete these applications by dragging the application icon straight to the trash...but i always have a feeling that they are never fully deleted. These suspicions were confirmed after google searching a bit. I heard even AppZapper and AppDelete don't do the job. In my /Library/Preferences folder, I have hundreds of .plist files and other stuff that I might not need. how can i clean up old messes from past applications?
