EFI update to address rare wake from sleep issues on mid-2011 MacBook Air's now available
If you have a mid-2011 MacBook Air and have been experiencing issues with the system taking longer to wake from sleep than expected or your fans run at full speed when after waking device up, Apple has now made available a new EFI update that aims to address those problems.
It's a small 4.3MB download available directly from the Apple website and should be ran over top of EFI versions 0077.00, 0077.08, 077.0E, 0077.0F with OS X 10.9.2 and later. Luckily, you won't really have to check all that yourself though you can if you wish.
The installer once downloaded will double check to ensure it can be run on your computer before actually installing so even if you have a mid-2011 MacBook Air and just want to ensure you're not affected, you can download the update and run it to see if it applies to your system.
