Schmitz Apple has issued [1]EFI Firmware Update 2.6 for the MacBook Air models that were released in June, 2012. The update brings resolution to a color issue with connected HDMI displays, an issue that caused the system to freeze if a Thunderbolt device was unplugged while in standby mode, and an issue with properly booting Windows using Bootcamp. It requires OS X 10.8.2 Mountain Lion. As always with firmware updates, we recommend relying on the App Store to ensure you get the firmware update for your specific model, and being careful not to interrupt the update process.
