Uninstalling applications in Mac OS X is very different than uninstalling in a Windows OS …and much easier.
While most Windows programs include an uninstaller that can be run through using the Add/Remove Programs in the control panel, Mac OS X has no such feature.
Most of the time, uninstalling in MAC OS X is this simple, just drag-and-drop the app to the trash.
The easy and simple way:
1. Open the Applications folder.
2. Drag to the trash the icon of the program you want to uninstall.
3. Empty the trash.
However, for some programs, removal is more complicated. When installed, these programs create files in several locations. If a program has an uninstall utility associated with it, You may us it to uninstall the program.
You can use CCleaner for Mac to clean up.
CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system.
I only recommend using CCleaner if you have installed and uninstalling a lot of programs over time.
