Apple Issues a MacBook Air EFI Update to Address Several Issues
Shortly after Apple released an SMC update for 2013 MacBook Airs, the company issued an EFI firmware update for late-model machines, fixing a memory-related problem that can cause systems to randomly reboot. Apple’s MacBook Air EFI firmware update 2.8 aims to rectify a batch of issues that some users have experienced with mid-2013 and early-2014 models.
More specifically, the updates improve reliability during booting and waking the computer from sleep while USB and Thunderbolt devices are connected. Apple doesn’t spell out what problems users reported but the company’s support Communities forum lists a number of possibilities from fast battery drain while sleeping to system freezes.
Along with its hardware connectivity problems, the new EFI firmware solves an issue where users’ MacBook Airs fail to properly sleep the built-in display when an external monitor is connected. The issues are limited to use under Windows using Boot Camp. The recent update also addresses a memory issue that, in some cases, causes the system to randomly reboot.
The MacBook Air EFI Firmware update 2.8 comes in at 4.8 MB and can be downloaded through Apple’s Support webpage.
