If you’ve got one of the 2011 MacBook Airs and have been waiting to umbilical it by Thunderbolt to one of Apple’s massive new 27-inch Cinema Displays, Apple’s just pushed live the software that will tell your notebook just how to do so.
The MacBook Air EFI Firmware Update 2.1 clocks in at just a hair under 4 megabytes, and not only includes enhanced stability for Lion Recovery over the Internet, it also improves Thunderbolt compatibility and adds support for the forthcoming display.
Here are the notes:
This update includes fixes that enhance the stability of Lion Recovery from an Internet connection, and resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on MacBook Air (mid 2011) models.
For more information about Lion Recovery, please visit https://www.apple.com/macosx/recovery/.
The MacBook Air EFI Update will update the EFI firmware on your notebook computer. Your computer’s power cord must be connected and plugged into a working power source. When your MacBookAir 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 MacBookAir during this update.
You can grab the EFI Update through Software Update, or directly by clicking this link.
