Apple released a firmware update on Monday for its latest 2012 Mac mini models, which addresses a problem with flickering video on its HDMI output.

As noted by AppleInsider, users began reporting problems with HDMI output shortly after the Ivy Bridge-equipped Mac minis began shipping in late October. The problem is characterized by a short blip in the video output when the computer falsely detects that an attached monitor or HDTV has been disconnected. The connection is reset automatically, but the problem tends to occur every couple of hours according to several user reports.

Mac mini EFI Firmware Update 1.7 "addresses HDMI video flicker issues on Mac mini (Late 2012) computers," according to Apple, and is "recommended for all users." The update can be installed via the Mac App Store on affected machines.
