Apple releases MacBook Pro EFI Firmware Update 2.2 (Update: Mac mini updated too)

by Chris Rawson Sep 14th 2011 at 5:30PM

Apple has released MacBook Pro EFI Firmware Update 2.2 for 2011-model MacBook Pros. The update addresses the same Thunderbolt and OS X Lion Internet Recovery issues as the EFI Firmware Update issued two days ago for 2011-model MacBook Airs.

The 4.17 MB firmware update is available at Apple's site and requires you to ensure that power is not interrupted to your MacBook Pro during the update; firmware updates are Serious Business which, if interrupted, can put your Mac in Very Bad Shape.

Other sites have noted that the recent spate of firmware updates for Thunderbolt-enabled Macs points to the imminent availability of Apple's new Thunderbolt-enabled Cinema Display.

Update: The 2011-model Mac mini has been issued the same firmware update to address the same issues.

After installing this update I can no longer netboot a MacBook Pro. When I hold in the option key it searches for a wireless network and won't find our netboot server.

According to OWC, this update also solves the 6.0 Gb/s Sata performance. Great!

The only problem I'm having with my '10 is power supply, and it's a HUGE difference :/... I went to the apple store and they tested by batter and it's completely okay, can still hold 90% charge.
