Apple releases MacBook Air EFI Firmware Update 2.0

Apple today released MacBook Air EFI Firmware Update 2.0 which recommended for MacBookAir (11-inch and 13-inch, late 2010) models.

This update resolves a rare issue where MacBook Air boots or wakes to a black screen or becomes unresponsive. This update is recommended for all 11-inch and 13-inch MacBook Air (late 2010) models.

The MacBook Air EFI Update will update the EFI firmware on your notebook computer. Your computer’s power cord must be connected and plugged into a working power source. When your MacBookAir restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBookAir during this update.

Boot ROM or SMC Version Information: After this update has successfully completed, your Boot ROM Version will be: MBA31.88Z.0061.B01.1011181342

The ROM itself is: 0061.01

  1. Okay, that was the scariest software update I have ever done.
    Between a weird beep, blank screens two restarts, and a progress bar under the Apple icon on the start up screen between them, It clearly had me wonder WTF?
    All seems okay now, reply entered on my 11.6 MBA
    No snappiness changes noticed just yet.

  2. how utterly perfect. i ordered the 13″ airbook the day it came out and haven’t had any issues thankfully, until earlier today i started having the issue where it was a black screen after waking from sleep. it was intermittent but troubling. took a quick look at software update before closing it down for the night, saw this, fixing exactly this issue.

    update installed, no problems. standard firmware update process, reboot, beep, grey screen progress bar, second reboot. after the second reboot machine was up and running in 6 seconds. quickest boot i’ve seen it do yet.

    kudos apple, great work!

  3. I downloaded the update, and attempting to run the package returns a “this application not supported on this system” message.

    Either my very new MBA 13″ already has the updated EFI version, or I’m doing something wrong in applying it.
