  • Users Reporting Installation and Crashing Issues with Latest MacBook Air EFI Update


    Apple’s most recent EFI update for the mid-2011 MacBook Air models seems to contain a bug that in some cases fails to install or more seriously creates system crashes. Apple pushed out the MacBook Air EFI update 2.9 last week to address sleep/wake issues seen on the mid-2011 hardware running OS X 10.9.2 and later.

    Recently, users began reporting the update as flawed on Apple’s Support Communities forum, citing a number of problems including installation bugs and system lockups. The exact cause of the issue remains unknown, though a corrupted file may be to blame as users with identical hardware are seeing varied negative effects. One user with a “bricked” Air took their machine to an Apple Store Genius Bar, where the technician performed a ‘soft” SMC reset to successfully remove the tainted EFI update and bring the computer back to life. The issue was then reported to Apple’s engineering department, though the company has yet to remove the EFI update page.

    Apple’s MacBook Air update was meant to fix an issue that causes the laptop to take longer than expected to wake form sleep. It also addressed the problem that could cause the computer’s fans to run at full speed after waking from sleep.

      I had all kinds of problems with this update. My machine crashed the first time I tried to install it. Had to fiddle with holding down the power button for several minutes and it finally booted. Then it ran unusably slow. Got a spinning beach ball anytime i clicked the mouse. I very slowly tried to reinstall the update--only clicking the mouse once every minute or so. Finally after reinstalling about five times, it took. Haven't had a problem since. If you're having problems, keep trying to reupdate. And don't get impatient and start pushing buttons halfway though. Let it sit for a half hour if it seems stuck during the installation process.
