You could have downloaded Uninstool 2.0 for Mac from our application library for free. This software for Mac OS X is a product of ForMacx. The software lies within System Tools, more precisely System Optimization.
From the developer:
Remove unwanted App correctly and completely
Thorough Deletion of Unnecessary Apps
Simply dragging apps into Trash does not delete them thoroughly. These programs normally leave some unnecessary files (Log, Cache, Preferences, Service, Crash Report) which amass over time, take up a great part of the hard disk and slow down your system. But now you can leave all the trouble to Uninstool.
