I am currently running OS X 10.7.2 on a MacBook Air. As a quick note, while this program was installed through Steam, I don't think it's a Steam issue.
Background: Through Steam, I recently downloaded the Team Fortress 2 Beta to this Mac and then removed it via Steam's "Delete Local Game Content." This has left the "Team Fortress 2 Beta" icon stuck on the Launchpad, and I cannot remove it.
All of the typical methods for removing an icon have not worked (i.e., dragging to trash, Control+Option+Command+Left-Click, holding down left-click over the icon until icons start shaking, et cetera). I have uninstalled Steam (dragging icon in "Application" folder to trash) and removed all game content (deleted associated Steam directory in "Application Support") and that has not deleted the icon.
I have deleted the "Application Support" folder to try and force the Launchpad to reset itself; it did reset, but the icon remained there. There is also not an icon in the Application folder for the game. Clicking on the icon in the Launchpad does nothing, now that Steam is removed.
How do I remove this orphan icon from the Launchpad?
