MacBook Pro EFI Firmware 1.3 out, may cause issues

Apple released an EFI firmware update for MacBook Pro yesterday, so if you haven't grabbed it yet, it should be available in MacBook Software Update. The release isn't a big one, but is supposed to fix a display issue on the 15-inch MBP models.

Unfortunately, a few people are finding the update actually does exactly the opposite, and creates problems with the display. Word has it that resetting the PRAM (push CMD+Option+p+r at boot, and you have to do it a few times, so you have to push the PRAM a lot) helps, but even if it fixes the problem temporarily, but who knows what else is happening here-- Apple may have to release an update to fix the update that fixed the original problem.

Thanks Eddie, Jonathan, and all others who sent this in.
