How to Delete Apps from Launchpad on a Mac

Deleting Apps from the Terminal

1. 
   Open the Terminal. You can do this by going to your Finder and selecting "Go" and then "Utilities." A window will appear where you can choose the black icon entitled "Terminal." You can also do this by clicking on the magnifying glass in the upper right-hand corner of your screen and typing "terminal."
2. 
   Enter the following command: sqlite3 ~/Library/Application Support/Dock/*.db "DELETE from apps WHERE title='APPNAME';" && killall Dock. For example, if you are trying to delete an app called "LEMON," you would enter the following command: sqlite3 ~/Library/Application Support/Dock/*.db "DELETE from apps WHERE title='LEMON';" && killall Dock. You can find the exact name of the App by going to the Applications folder and searching for it. After you have entered the above command, hit "Enter."^[2]
3. 
   Check to see if the app has been successfully deleted. After you enter the delete command, Launchpad will automatically refresh and the app should be gone.
