How to Delete an Application Downloaded from the Mac App Store
JohnThis guide will teach you how to quickly delete an application from your Mac that was downloaded from the Mac App Store. This method uses Launchpad.
If you don't still have the Launchpad icon in your dock, open Spotlight by pressing CMD-SPACE and then type "Launchpad" and press ENTER.
The apps you can delete will start to jiggle and show an x icon. If the app shows an x it can be deleted.
Confirm that you want to delete the app by click Delete or simply hitting enter.
If you're a student or use your Mac for work, then you know what it's like to have multiple windows or apps open at a time, and how messy that can sometimes make your Mac desktop.
