App Cleaner is a small program that allows you to thoroughly uninstall unwanted programs.
Now, when you install a program on a mac it spreads it wings to many areas of your harddrive, which are often hard to find when you want to uninstall the program (damn you).
App cleaner finds this hiding files, and deletes them all when you drag the origional program to AppCleaner. Simple. Easy. And most importantly, quick.
You can find AppCleaner here. And it is free.
I do admit, it isn't a program I use a great deal, but when I do use it I thank my lucky stars I have it. I highly recommend itPin It
