I wonder if the same trick will save my Mac Mini from its abysmal gaming performance. It's a late 2009 with a 9400M. If I try to play L4D2 on the Windows side, the computer crashes. If I play it on the Mac side, I turn the fan up all the way using SMC Fan Control and the game still plays. However, the knowledge that Mac graphics drivers are crappy compared to what I could be using on the Windows 7 side kind of irks me. Oh well...this is a non-issue. What am I doing trying to play a game on the 2009 Mac Mini anyway!?
