Apple issues EFI update for late-model MacBook Airs

updated 08:15 pm EDT, Tue June 10, 2014

Comes one day after SMC update, fixes reliability issues with peripherals, more

Just one day after issuing an SMC firmware update for mid-2013 model MacBook Air units, Apple on Tuesday added an EFI firmware update package for both the 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," the company says. It also addresses a rare memory issue, and sleep issues seen while running Windows under Boot Camp.

The release notes for the package, numbered as version 2.8, say that the update will fix "a rare memory issue 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." The update is recommended for both the mid-2013 and early-2014 models.

As a firmware update, Apple recommends that the unit be plugged in or have a minimum charge of 25 percent or more before attempting the firmware upgrade. Installing the package will cause a restart, with a status bar to indicate the progress of the update. "Your computer's fans will run at full speed during the update but will return to normal speed once the update completes," Apple notes in its instructions. As with all firmware updates, the company says uses must not "disturb or shut off the power on your computer during this update."

The 4.8MB file is available for the two models of MBA running either OS X Mountain Lion (10.8.5) or OS X Mavericks (10.9.2 or higher). It is available through Software Update for owners of the correct model of MacBook Air, and can also be downloaded in a standalone installer form from Apple's support web pages.
