Firmware Update 1.0 for MacBook Air 2012 Not Installing The firmware update 1.0 for my MacBook Air (2012) is not installing. I do not have the disk encrypted and I have tried an SMC reset. I also let the mac sit for a minute after shutting down before turning it back on just as the update suggest. Every time I boot my air back up it tells me in the App Store that there is still an update that needs to be taken.

Any suggestions?
Do you happen to have FileVault enabled? If so, you cannot update the firmware on the drive at this state. 

The firmware update happens before the OS decrypts/unlocks the drive, thus at FW update time, the drive is not accessible.

The only solution I know is a bit of a pain: 


turn off FileVault
run the update
turn FileVault back on
