Apple on Monday posted an EFI update for its thin-and-light MacBook Air, addressing two wake from sleep issues including a rare problem that causes the computer's fans to spin at full speed unnecessarily.
Apple's MacBook Air EFI firmware update 2.9 targets problems seen on mid-2011 models running OS X 10.9.2 and later.
The release notes say EFI version 2.9 fixes an issue that causes some systems to take longer than expected to wake from sleep. Also addressed is a rare issue that could cause system cooling fans to run at full speed after waking from sleep.
Apple notes the update should only be installed over EFI versions 0077.00, 0077.08, 0077.0E and 0077.0F on OS X 10.9.2 or higher.
The latest MacBook Air EFI update version 2.9 comes in at 4.3MB and can be downloaded via Apple's Support webpage or Software Update.

That's nice to know Apple still supports my 2011 MBA. That's what buying Apple gets you. Name another PC manufacturer that supports 3-year old machines like that.

Well, really they are supporting Mavericks here, I'd say.
So Apple finally decided to get around to fixing a problem that is over three years old? I wouldn't consider that great customer support.
No, try again. You can do better.
Oddly, I have installed the EFI update three times and it continues to reappear in my App Store list of updates to be installed.
