Apple released two new EFI firmware updates for Macbook Pro and Mac mini models, fixing some Lion issues and prepping the devices for the new $999 Apple Thunderbolt Display. Notable is the fact that the Macbook Pro update appears to add the Lion Internet Recovery feature that it had previously lacked. The Macbook Pro EFI Firmware Update 2.2 fixes Thunderbolt Display compatibility problems with early 2011 models and enables Lion Recovery over an internet connection. The Lion Internet Recovery feature was previously limited to only the new Macbook Air and Mac mini models. It allows a user to boot from the Mac’s recovery partition and reinstall Lion by downloading it over the internet in the case of a catastrophic problem. The Mac Mini EFI Firmware Update 1.3 for mid-2011 Mac mini models improves the stability of Lion Internet Recovery and also fixes problems with Apple’s new Thunderbolt Display and boosts performance in the Thunderbolt Target Disk Mode. Apple released an update for mid-2011 Macbook Air models last week, which also addressed Thunderbolt Display issues. Mac OS X 10.7 Lion or later is required to apply them, and when installed the boot ROM version on the Mac Mini will be MM51.88Z.0077.B0A.1109091226 and for the MacBook Pro it will be MBP81.88Z.0047.B1E.1109091244.
