A video flicker issue experienced by owners of new-generation Mac minis has been patched in the latest EFI Firmware Update from Apple. The package weighs in at 4.53 MB and applies to Late 2012 Mac mini models exclusively.
Confirmed by Intel late last month, the screen flickering issue had already been wrapped up in a bug report and sent to Apple around November 29.
The chip maker said last month, “Apple will provide the driver with the fix when they are done configuring our driver (that has the fix). An ETA on this is currently unknown.”
Instead of waiting to wind up development of OS X 10.8.3, Apple decided to release an individual patch for the HDMI video flicker issues on Mac mini (Late 2012) computers.
The update is recommended for all users. As usual, the Cupertino giant explains that “Your computer's power cord must be connected and plugged into a working power source.”
“When your Mac mini restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your Mac mini during this update,” says the Mac maker.
The Mac mini EFI firmware will be updated to 0106.03, according to the company’s Support site.
The system requirements listed in the changelog only mention “Mac mini (Late 2012),” but it is reasonable to assume that the patch installs on multiple versions of Apple’s Mac operating system.
Compatibility should begin at OS X 10.6 Snow Leopard. OS X 10.7 Lion should also be supported, while Mountain Lion is without a doubt targeted as well.
Supported languages include Deutsch, English, Français, Español, Italiano, Nederlands, Dansk, Norsk Bokmål, Polski, Português, Português Brasileiro, Pусский, Suomi, Svensk, Chinese, Japanese, and Korean.
