Completely uninstall an application

Solution 1:

There are several 3rd-party “un-installers” available for Mac. The one I use is AppZapper.

There may be files in "~/Library/Application Support/{folder name of app}" and there may be a preference file in ~/Library/Preferences/.

Sandboxed apps have their data in "~/Library/Containers/{folder name of company}"

Some applications may also install more complicated things like kexts. Most of those apps will have their own uninstallers.

Solution 2:

Deleting the application from the Applications folder is deleting the application. Some will store further data in ~/Library/Application\ Support/.

Solution 3:

Well known you can go ahead and download "AppCleaner". Find it here : http://www.freemacsoft.net/appcleaner/ [Supports OS X 10.6 - 10.9 Currently]

Here's another way to delete some apps.

When you install a application, many of them will come when you click "Launchpad" To delete a app try doing this :

1 : Click Launchpad

2 : Click and hold the app you want to delete [ NEXT CLICK ON THAT X LITTLE BUTTON TO DELETE YOUR APP ]
