Owners of a new-generation MacBook Air may want to check their software updaters as Apple has rolled out a new EFI firmware update that addresses a trio of issues with mid 2012 models.

Apple this week released MacBook Air EFI Firmware Update 2.6, a rather small (4.76 MB) package installer that injects three patches into mid 2012 MacBook Air laptops.

“This update is recommended for MacBook Air (mid 2012) models,” Apple states. “The MacBook Air EFI Firmware Update will update the EFI firmware on your computer,” the company adds, and proceeds to enumerate the bugs it squashes.

“This update fixes a color issue with HDMI displays connected to MacBook Air, resolves an issue with Windows which can prevent MacBook Air from booting properly, and also resolves an issue where unplugging a Thunderbolt device may cause the system to freeze when waking from standby,” reads support document DL1623.

The Cupertino, California-based computer giant insists that owners of an affected MacBook Air will have to connect their MagSafe adapters before proceeding with the installation of the EFI firmware update.

“Your computer's power cord must be connected and plugged into a working power source. When your MacBook Air restarts, a gray screen will appear with a status bar to indicate the progress of the update,” the company explains.

Apple advises customers to be patient and not interrupt the update process.

“It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBook Air during this update,” reads the documentation.

Targeting OS X 10.8.2 (the latest version of Mountain Lion), MacBook Air EFI Firmware Update 2.6 supports multiple languages, including Magyar, Čeština, Deutsch, English, Français, Español, Italiano, Nederlands, Dansk, Norsk Bokmål, Polski, Português, Português Brasileiro, Pусский, Suomi, Svensk, Arab, Chinese, Japanese and Korean.
