You can uninstall apps you got from the Mac App Store, from other websites, or from discs.
Apps downloaded from the Mac App Store: Click the Launchpad icon in the Dock, hold down an app’s icon until all the icons begin to jiggle, then click an app’s delete button X.
If you later want the app, you can reinstall it from the Mac App Store.
If an icon doesn’t have a delete button, it can’t be uninstalled in Launchpad.
For more information about Launchpad, see Use Launchpad to view and open apps.
Apps that have an uninstaller: In the Finder sidebar, click Applications. If an app is inside a folder, it might have an Uninstaller.
Open the app’s folder. If you see Uninstall [App] or [App] Uninstaller, double-click it and follow the onscreen instructions.
Apps that don’t have an uninstaller: In the Finder sidebar, click Applications.
Drag the app from the Applications folder to the Trash (located at the end of the Dock), then choose Finder > Empty Trash.
If you change your mind, before emptying the Trash, select the app in the Trash, then choose File > Put Back.
WARNING: When you empty the Trash, the app is permanently removed from your Mac. If you have any files that you created with the app, you may not be able to open them.
