In the last 24 hours Apple has posted two separate EFI firmware updates for Thunderbolt-equipped Macs and a software update that provides support for the new Apple Thunderbolt Display. All are available for download from Apple’s Support Downloads Web page.
A MacBook Pro EFI Firmware Update 2.2 is aimed at MacBook Pro (early 2011) models.
This update enables Lion Internet Recovery which starts Lion Recovery directly from Apple servers over a broadband Internet connection if the built-in recovery is unavailable. It also includes fixes that resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on MacBook Pro (early 2011) models.
Mac mini EFI Firmware Update 1.3, meanwhile, is aimed at Mac mini (mid 2011) models.
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 Mac Mini (mid 2011) models.
Thunderbolt Software Update “provides support for the Apple Thunderbolt Display and bug fixes for Thunderbolt device compatibility,” according to Apple.
