Apple Brings Lion Internet Recovery to More 2010 Macs
- MacBook Air EFI Firmware Update 2.3 (2.98 MB):
This update enables Lion Recovery from an Internet connection on MacBook Air (Late 2010) models and addresses an issue where the system could restart if the power button is pressed immediately after waking from deep sleep.- iMac EFI Update 1.8 (3.02 MB):
This update enables Lion Recovery from an Internet connection on iMac (Mid 2010) models.- MacBook Pro EFI Firmware Update 2.6 (3.18 MB):
This update enables Lion Recovery from an Internet connection on MacBook Pro (Early 2010) models.Apple introduced Lion Internet Recovery on new MacBook Air and Mac mini models introduced last July alongside OS X Lion itself. The feature adds a minimal bootable install onto a machine's firmware to allow it to connect the Internet and download the full Lion operating system for installation.
OS X Lion by default installs a recovery partition on the machine's hard drive for this purpose, but for users who are installing a blank hard drive or whose recovery partition becomes inaccessible, Internet Recovery provides yet another fallback option for Lion installation.
The company has extended the Lion Internet Recovery feature to a number of older Mac models over time, with the most recent addition coming two weeks ago and adding support for the Mid-2010 versions of the 13-inch MacBook Pro, white MacBook, and Mac mini. One notable exception is the Mac Pro, which has yet to see even the currently-shipping models support Lion Internet Recovery.
