Today I had some apps remain on LaunchPad after deleting them from the applications folder. Apple has some work to do as there was no way of removing these apps from LaunchPad except through terminal. Here is how to use Mac Terminal to remove apps from LaunchPad.
Replace APPNAME with the name of the app. It’s case sensitive.
sqlite3 ~/Library/Application\ Support/Dock/*.db “DELETE from apps WHERE title=’APPNAME’;” && killall Dock
Here’s an example removing Picassa
sqlite3 ~/Library/Application\ Support/Dock/*.db “DELETE from apps WHERE title=’Picassa’;” && killall Dock
