Or any other cleaner software? I come from a Windows background and even though I've switched to Mac, I feel the need to keep my system as clean as possible. It's just a hold over from 20+ years of Windows. I know that many say that you don't need to clean up a Mac, but I also know that there are bits and pieces of junk cluttering up my drive. Anyone have any recommendations? AVG seems to get a lot of praise in the Mac App Store.
