MacBook Pro Retina EFI Updates 1.2 and 1.3

by Agen G. N. Schmitz

Apple has released two EFI firmware updates that provide targeted fixes for specific models of the recently released lineup of the MacBook Pro with Retina display (see “New Retina MacBook Pro Models Thinner, Lighter, and Cheaper [1],” 22 October 2013). EFI Update 1.2 [2] is aimed at the high-end version of the 15-inch MacBook Pro model with Nvidia GeForce GT 750M graphics, addressing a rare problem that limits the performance of the Nvidia graphics processor after a system wake or boot. EFI Update 1.3 [3] is directed at 13-inch models to fix an issue where the built-in keyboard and trackpad could become unresponsive. As always with firmware updates, we recommend relying on Software Update to ensure you get the firmware update for your specific model, and be careful not to interrupt the update process.
