Apple has just released three new EFI Firmware Updates, all of which are meant to benefit 2010 models of the iMac, MacBook Air, and MacBook Pro. The main purpose of the updates is to add Lion Internet Recovery to these Mac models.
Release notes for each update follow:
This update enables Lion Recovery from an Internet connection on MacBook Pro (Early 2010) models.
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.
This update enables Lion Recovery from an Internet connection on iMac (Mid 2010) models.
Lion Internet Recovery, a feature introduced into OS X with the release of Lion, allows users to re-download the entire operating system from Apple’s servers without having to go through the Mac App Store. This feature is most useful when access to the Mac App Store is unavailable for whatever reason, and a reinstall of Lion is also necessary for whatever reason. The feature was only available to the newest Mac models at first, but has been since added to older models through software updates such as today’s EFI Firmware Updates.
