Apple on Tuesday released several EFI firmware updates for its 2010 Macs to enable the Lion Internet Recovery feature to the older machines.



From AppleInsider:

Each of the upgrades adds support for Lion Recovery over an Internet Connection. The feature first made its debut on last year's MacBook Air and Mac mini models, both of which lack optical drives allowing for more traditional recovery methods. Internet Recovery lets users start their Macs directly from Apple's servers. Macs released earlier in the year, such as the Thunderbolt MacBook Pro and iMac, received an EFI firmware update last fall to add the feature.

Tuesday's MacBook Air firmware update also addresses an issue where the system would sometimes restart when the power button was pressed immediately after waking from deep sleep.
