    Does anyone know if its possible to downgrade your EFI? I'm having a graphics problem that can usually be fixed on PCs by altering some BIOS settings, so I figure a manual EFI update would be as close to that as I can get on a mac.

    Quick bump so this doesn't get drowned out by all the "10.5.2 killed my MBP!!!!! OMG PLZ HELP!!!!!!!!" threads.

    If there is an earlier EFI update for your Mac Book you can try it. My guess is that it won't help but I could be wrong ;). Worse case scenario is that it simply won't apply itself.
