MacBook Air EFI Firmware Update 2.9
Apple has released MacBook Air EFI Firmware Update 2.9 for MacBook Air models released in mid-2011. Ostensibly, the update addresses two issues related to waking from sleep — a bug that prevented waking in a timely maner and a problem that caused fans to run at full speed after waking. However, there are multiple reports on a discussion thread at Apple Support Communities that installation of the firmware update is causing some MacBook Air laptops to shut down completely and not start up again for a lengthy amount of time (so much for that timely waking fix). Additionally, other users report still seeing the EFI update in the
Mac App Store’s Update section even after applying the firmware multiple times. This might be one to wait on for a few days to see if Apple reissues EFI Firmware Update 2.9. (Free, 4.1 MB, 10.9.2+)
The download link seems to be broken at this time.
looks like it might have crept out too early? Download link page looks only half finished (e.g. button which says "Articletemplate.download"!)
Even better, I was notified of the update via App store and after i clicked install it quit out of everything to restart and then just hung there!
Giving me a nice warm and fuzzy apple feelling!
All is well after a full shutdown and restart but there is/was no FW update :-(
I didn't really need that near heart attack.
Shutdown after update and wouldn't restart for several minutes.
mine just did the same thing.....its been about 6 hours and still nothing. I have been trying to find an answer online, but will probably end up at the apple store.
Apple must have pulled it as the link in the article now goes nowhere.
Bluetooth no longer works. Wireless adapter is intermittent. This is not a good, verified release. DO NOT INSTALL!!!!
