Apple has released Mac mini EFI Firmware Update 1.7, which deals specifically with video flicker issues caused by the HDMI port on the recently released Mac mini model (see “Apple Releases New iMac, 13-inch MacBook Pro, and Mac mini,” 23 October 2012). The update requires OS X 10.8.2 Mountain Lion. As always with firmware updates, we recommend relying on the App Store to ensure you get the firmware update for your specific model, and being careful not to interrupt the update process.
