EFI Update Brings Lion Recovery to iMacsby Andrew Cunningham on October 27, 2011 5:15 PM EST
Apple has released a new firmware update for the Sandy Bridge iMacs that enables Lion Internet Recovery, allowing customers to connect to Apple's servers in the event that they need to do a clean install of OS X Lion. It additionally fixes issues with the Apple Thunderbolt Display and Thunderbolt Target Disk Mode.
Lion Recovery, designed to replace recovery discs in the post-Lion era, was originally introduced in the new MacBook Air and Mac Mini models earlier this year, and was extended to the Sandy Bridge MacBook Pros last month.
The update, which requires OS X 10.6.8 or any version of 10.7, can be downloaded using Software Update, or directly from Apple's support site.
