EFI Firmware Update brings Lion Internet Recovery to 2010-model Macs

Apple has released three EFI Firmware Updates for 2010-model Macs, including the iMac, MacBook Air, and MacBook Pro. This update enables Lion Internet Recovery on those older Macs. Introduced in OS X Lion alongside the mid-2011 updates to the MacBook Air and Mac mini, Internet Recovery enables access to disk repair or OS X Lion installation options via a broadband internet connection. This is intended for use on a failed hard drive or a blank drive that's never had OS X installed on it.

Together with a series of earlier firmware updates, all Macs introduced from 2010 onward now have access to Internet Recovery features -- with just one notable exception. Even the newest Mac Pro is still excluded from the support list for Internet Recovery.
