This update fixes a color issue with HDMI displays connected to MacBook Air, resolves an issue with Windows which can prevent MacBook Air from booting properly, and also resolves an issue where unplugging a Thunderbolt device may cause the system to freeze when waking from standby.

The MacBook Air EFI Firmware Update will update the EFI firmware on your computer.

Your computer's power cord must be connected and plugged into a working power source. When your MacBook Air restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBook Air during this update.
