Apple Launches New EFI Update 2.9.1 For 2011 MacBook Air to Solve Installation Problems

Wednesday July 30, 2014 3:16 PM PDT by Juli Clover
Apple today re-released its EFI Firmware 2.9 update for 2011 MacBook Air models after the original EFI update appeared to be causing trouble for many MacBook Air users.

The update, originally released on July 15 to address sleep/wake issues, caused some MacBook Air machines to shut down completely for several hours. On other machines, the update simply refused to install. Today's re-released software, labeled 2.9.1, presumably fixes these issues, allowing the update to be properly installed.

So weird, even though updates generally mean bugs, I'm always jealous when there isn't an update to my specific piece of hardware. :D

nzalog, your signature isn't completely accurate.


Your face is inaccurate! :eek: ;) :D

You are one of the first to actually notice that. :)

It's almost like they are trying to force people to upgrade by deliberately slowing older machines down ;)


I agree. I think middle-upper management has a hand in either deliberately doing this - or they just don't care when they accidentally break older machines a bit and don't put very much effort into fixing to try to encourage upgrading.

That being said, this EFI update seems to have fixed my fan from screaming like a jet engine all the time, and has also sped up waking from sleep considerably so I'll throw a "thank you" out to the engineer at Apple who managed to fix this - while having to deal with his pointy haired boss who was hindering his every step.



If they really want me to upgrade, they need to throw me a bone. A specific bone: rMBA. Nothing else will satisfy.

Works like a charm, like it always did.

Maybe it is because I had a crappy PC for so many years, but this computer is blazingly fast since day 1, 3 years ago.

Heck, the OS will eat RAM as much as it can, and that's ok because swap is always minimal (thank you mavericks!), and I feel no difference in performance when all RAM is being used.

Great machine. Best laptop ever, indeed. I believe that it will take me more 5 years to update to a new MBAir, but Apple clearly gained my trust and admiration because of this computer.
