I purchased a game (Broken Sword DC) via Steam and the game runs just fine but the icon in the dock and for the .app bundle has a prohibited sign across it - the same kind you see with a Classic (Mac OS 9) application on Leopard or later. As far as I can see the permissions from the get info are OK the only possible clue is in the terminal doing an ls -al I can can see an @ symbol - which I think has something to do with ACLs?
Any ideas how to get rid of the prohibited sign?
