EFI updates extend Lion Internet recovery to more Macs

New Mac systems support the ability to boot to Apple's Internet recovery service that provides Lion users with an option to reinstall OS X over the Internet, instead of using a local boot disk to reinstall OS X.

In an effort to bring this ability to some earlier-model systems, Apple recently released EFI firmware updates for 2010-model MacBook, MacBook Pro, and Mac Mini systems that enable this option.

In a new round of EFI updates released yesterday, Apple appears to be filling out support for this feature in all of its 2010 models, now bringing this feature to the … Read more

Mac EFI firmware updates enable OS X Lion Internet recovery

Apple releases more EFI firmware updates

On Monday, Apple released an EFI firmware update for MacBook Air systems that in addition to fixing performance issues with Target Disk mode, implemented compatibility for the upcoming Thunderbolt displays that Apple is developing. Following this update, Apple today released two more updates for the Mac Mini and MacBook Pro systems which address the same problems and compatibility issues as the MacBook Air update.

EFI update preps MacBook Airs for new displays

In conjunction with the impending release of its new Thunderbolt Cinema Displays, Apple's pushed out a software update to its latest MacBook Air models that gets them ready to plug in to the new hardware, while fixing a handful of bugs in the process.

The EFI update, versioned 2.1, comes in at 3.9MB and promises to fix issues that arise when recovering Lion using the new Internet Recovery feature. The update is also aimed at improving performance in target disk mode when plugging in via Thunderbolt.

Of special note is the fix of an issue with plugging in to Apple's yet-to-be-released Thunderbolt Display, which has been marketed as a docking station of sorts for late-model MacBook Air owners.

For instance, those users can plug in to the display to get a Firewire 800 port, FaceTime HD camera, Gigabit ethernet and three USB 2.0 ports, extending the I/O that ships on Apple's smallest notebook, and demoing some utility for the computer's Thunderbolt port, which currently has just a handful of third-party accessories to make use of it.

Apple introduced its Thunderbolt Display alongside new versions of the MacBook Air, Mac Mini, and its Lion OS software update in late July, saying only that it would be launching that new display hardware "within the next 60 days." A report in MacRumors last week suggested that Apple was already in the process of shipping its $999 Thunderbolt Displays to stores. However, Apple continues to list it as shipping within the next "2-3 weeks" from its online store.… Read more
