Apple addresses 2012 Mac mini HDMI flicker issues with software update
Apple on Monday released a software update for owners of its recently updated Mac mini desktop, addressing an issue that would cause a connected screen to flicker.
Mac mini EFI Firmware Update 1.7 is a 4.53-megabyte download now available from Apple. It's compatible with the late 2012, Ivy Bridge powered Mac mini models released by Apple this fall.
Apple said the update, recommended for all users, will address HDMI flicker issues. Users must not disturb or shut off the power to their Mac mini while the firmware is updated.
Display flickering issues with the new Mac mini have been well documented in a popular thread on the Apple Support Communities forums. There, users have reported that the video from their Mac would cut out for a short period of time before returning.
The flickering issue happened relatively infrequently â about once every few hours, users said. However, it happened often enough that some users noticed it on a daily basis.
Users experienced the issue with a wide range of monitors, and also when using an HDMI to DVI converter.
The Mac mini was updated with Intel's latest Ivy Bridge processors and up to 16 gigabytes of RAM in a new model released in late October. The desktops also feature Intel HD 4000 graphics, Bluetooth 4.0, and up to 1 terabyte with a hard disk drive, or 256 gigabytes with a solid state drive.

Praise God! I thought it was just mine!
Sweet, that was getting old really fast.
I just took delivery of mine today. Heading out the office door to get home and set it up. I guess I'll do updates first!
It appears to have been an issue with the firmware/drivers for Ivy Bridge. Some Intel mainboards for "PCs" have the same issue. Intel said a driver/firmware update would resolve this. Glad it's out now, I've got an 2012 mini, with 2 Apple Cinema Displays, and it was driving me nuts, the HDMI output changes to "snow/static" for about 2 seconds, then back to the image. It was doing it every 2 hours or so. Annoying when you're watching a movie.
So far so good! This was the only issue I had with my Mini otherwise this this is awesome little machine. I take back what I said about this being a "down-grade revision" because of the discrete graphics issue. I ordered mine with the Fusion drive and added 16GB of RAM myself. Granted I'm not in to gaming, but this thing is truly a screamer for what I do. I'm waiting to see what's going to happen with Retina and iMac's before I spend that kind of money, for now this Mini will easily handle everything I can throw at it...
