Uninstalling on Mac OS X; let's solve it once and for all!
What can be considered the exact opposite of dragging an application to the Applications folder? Opening another application, dragging the unwanted application to that application, clicking a button, clicking another button, quitting? Nope!
The exact opposite would have to be... dragging the application to the trash. Ah, there you go! This is exactly what AppTrap does. Whenever you drag an application to the trash, a dialog window will pop up, asking if you want to delete the associated system files too. Simple as that.
AppTrap is a completely free utility for uninstalling applications on Mac OS X.
