Does anyone know how to fix an error I keep getting when starting a game. It says that it can't find "InterfaceLib--achResource trouble.
I own an iMac; first model(bondi blue or 'teal') revision B. I found that I can load the game before I install some games. My guess is that loads an out of date file and it needs the new one back. If I can get this file, I'm in the good. Thanks.

InterfaceLib is part of the System. It's the interface between Applications and Toolbox calls. What your Mac is telling you is that the Game is wanting a function that is not implemented in whatever version of the System you are running. Have you gotten the Firmware updates ? A game update might also eliminate the trouble.
