How to remove icons showing question marks of deleted apps from Launchpad? I updated GIMP from MacUpdates since then I got two Gimp icons in Launchpad. I also deleted the Gimp.app from finder but now i get this question mark on the gimp icon in Launchpad. How to completely remove both of these icons?

What is the cleanup step, here?
[Worked] In Yosemite open Launchpad, hold down control key and click on icon you wish to remove. A question mark should appear over the icon. Just drag and drop to Trash.
