MacBook Pro EFI Firmware 1.3 Update Released, Potential Issues Reported

Yesterday, Apple rolled out an EFI firmware update for the MacBook Pro, which is now available through MacBook Software Update. This update aims to address a display glitch found in the 15-inch model of the MacBook Pro.

However, it appears the update may not be performing as expected for some users.

Reports are surfacing that it creates problems with the display instead of fixing them. It has been suggested that repeatedly resetting the PRAM (by pressing CMD+Option+p+r during startup) might alleviate the issue temporarily.

This workaround requires persistence, akin to the repetitive actions described in Monty Python and the Holy Grail. Despite this, the underlying issue might still necessitate another update from Apple to fully resolve the complications introduced by this firmware patch.

Thanks to Eddie, Jonathan, and everyone else who contributed this information.
