Apple Pushes EFI Update For MacBook Pro With Retina Display, Should Fix CPU Hang-Ups

In the slew of software updates Apple released today, one EFI update has been pushed out for the 2012 MacBook Pro with Retina display. EFI 1.0 is recommended for all MacBook Pro with Retina owners, and you can download it now alongside OS X 10.8.2. Here’s what it fixes, according to Apple:

This update is recommended to MacBook Pro with Retina display (mid 2012) models. This update resolves an issue which can cause the system to hang during heavy processor loads, and resolves an issue where NetBoot does not function properly when using an Ethernet adapter.

If you’ve been noticing any inconsistencies or random CPU hangups on the new MacBook Pro, then this update should do the trick. Grab EFI 1.0 now in the Mac App Store.

    I can confirm that this update definitely makes a difference. Not only does the system stop locking up under high loads, but the performance of VMs seems increased, as well as a renewed feeling of over-all snappiness. I’m not sure how much is the EFI update, or 10.8.2, but kudos to apple for making a fast machine feel that much faster.
