Apple has released a trio of seemingly identical updates for recent Macs, including the Mac mini EFI Firmware Update 1.3, the MacBook Pro EFI Firmware Update 2.2, and the MacBook Air EFI Firmware Update 2.1. The updates improve the stability of Internet-based recovery operations under Max OS X 10.7 Lion, resolve unspecified issues when connecting to Thunderbolt displays, and improve the performance of Thunderbolt Target Disk Mode. As with any firmware update, you should read the installation instructions carefully before installing. To ensure you get an update only if it’s necessary, we recommend relying on Software Update; if an update doesn’t appear for you, it’s not appropriate for your Mac. (Free, 4 MB)
