REALLY REALLY need help with this. My MBP won't boot wit the 9400m graphics card, think it's gone. Unfortunately it's selected right now and i need to change the setting to the 9600m card. But l can't see the screen (its black). However in bootcamp (under the 9600m card) i can use the MBP, so if i can find the plist or file which tells os x which graphics card to use ill edit it under bootcamp and reboot HELP ANYONE?
