Apple has released a new firmware update for owners of 2011 MacBook Pro models with the purpose of enabling a new software component - Lion Internet Recovery, as well as to fix a number of issues.

According to the technology mammoth headquartered at 1 Infinite Loop, Cupertino, California, “[Macbook Pro EFI Firmware Update 2.2] enables Lion Internet Recovery which starts Lion Recovery directly from Apple servers over a broadband Internet connection if the built-in recovery is unavailable.”

Some recently discovered issues are also addressed with Macbook Pro EFI Firmware Update 2.2, Apple says:

“It also includes fixes that resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on MacBook Pro (early 2011) models.”

For the less technically savvy user, the company further explains that “The MacBook Pro EFI Update will update the EFI firmware on your notebook computer.”

Apple instructs users to have their computer's power cord connected and plugged into a working power source as the firmware update is being installed.

Users are to expect a gray screen with a status bar indicating the progress of the update as soon as the MacBook Pro restarts.

“It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBook Pro during this update,” the Mac maker adds.

With the update successfully completed, the Boot ROM version will be: MBP81.88Z.0047.B1E.1109091244, according to Apple.
