After rolling out OS X Mountain Lion 10.8.2 and iOS 6 for its iDevices yesterday, Apple has today rolled out a new EFI firmware update the mid-2012 MacBook Air and other Macs.
The v2.5 EFI firmware for the Air fixes some Turbo Boost related issues when using Boot Camp, which has been plaguing mid-2012 Air owners for quite sometime.
Below is the full change-log of the EFI firmware update for the mid-2012 MacBook Air(s) -:
This update is recommended for MacBook Air (mid 2012) models.
This update fixes an issue where Turbo Boost does not activate when using Boot Camp, and resolves an issue where NetBoot does not function properly when using an Ethernet adapter.
The first EFI firmware update for the Retina MacBook Pro fixes a bug where the system might just lock-up under heavy load, and also fixes the NetBoot not working when an Ethernet adapter is used.
Lastly, the v2.9 EFI firmware update for the non-Retina MacBook Pro fixes the system locking up issue under heavy loads and might need to be restarted manually.
Head over to ‘Updates’ tab in the Mac App Store to download and install the latest EFI firmware update for your Mac(s).
