Apple has released an EFI firmware update for its late-model MacBook Air lineup. The update – coming close on the heels of an SMC update for mid-2013 MacBook Air models – fixes a memory-related issue that can cause the machines to randomly reboot.
Apple’s MacBook Air EFI firmware update 2.8 was issued to fix a laundry list of issues some users have experienced with their mid-2013 and early-2014 models.
This update improves reliability when waking from sleep and when booting while certain USB and Thunderbolt devices are connected.
This update also addresses a rare memory issue that may cause the system to randomly reboot, and an issue where the system may not properly sleep the built-in display when an external display is connected while running Windows using Boot Camp.
Apple doesn’t specify exactly what problems users have reported, but the Apple Support Communities Forum lists a number of issues, ranging from fast battery drain while sleeping to system freezes.
The new EFI firmware also reportedly fixes an issue where MacBook Airs fail to properly put the built-in display to sleep when an external monitor is connected. This issue is limited to using Windows under Boot Camp.
The update is also said to address a memory issue that, in some cases, will cause the system to randomly reboot.
The MacBook Air EFI firmware update 2.8 can be downloaded via Apple’s Support webpage.
