How to Completely Uninstall a Program on Mac
The Mac operating system does not require uninstaller utilities like other operating systems. Mac OS X stores all the program files for a piece of software in one location, making the removal process straightforward and simple. To completely uninstall a program, you use the same process as if you were simply deleting a file.
Click the "Finder" icon on the dock.
Click the "Applications" entry to display a list of the programs installed to your Mac.
Click on the name of the program you want to uninstall, and drag it onto the "Trash" icon on the dock.
Type in the master password for the computer in the prompt that appears and click "Continue" to uninstall the program from your Mac.
Restart your computer to complete the removal process.
