Q: HDMI Output Failure on 2-Mini's After 10.9.3 Update
I have two separate (Late 2012, OS X 10.8) Mini's that are both (2.6 GHz Intel Core i7, 16 GB 1600 MHz DDR3) that have been hooked-up to identical Flanders Scientific professional HD monitors via HDMI cables from the computer output to HDMI / DVI adapters into the monitor input and they have worked flawlessly in that configuration since purchase in July of last year. THAT IS UNTIL, I made the stupid mistake of installing OS X 10.9.3 ---
I updated both Mini-A and Mini-B within a few minutes of eachother while they remained online and wired to the monitors in that identical configuration. Mini-A was the first to complete the download and install of 10.9.3 and when it rebooted, the display image did not return. Subsequently, a few minutes later, Mini-B completed the download, install and reboot with the identical result of missing display image.
Monitor info:
2 x Flanders Scientific LM-2140W, 1920x1080, 10 bit, switchable multi-input (2 x HD/SDI, YPbPr & RGB Component, 1 x SD/SDI, DVI-I / DVI-A / DVI-D switchable YPbPr / Limited RGB / Full RGB)
Needless to say, I have been fiddle-f***ing around trying to resolve the issue for more than a week to no avail. The HDMI output signal is no longer present on both computers and the only way to feed a signal to a monitor is now via the thunderbolt / mini-display port output using a Mini-Display Portt to DVI-I or DVI-D adapter at the computer to DVI cable into the monitor.
Troubleshooting Procedure included.
PRAM / NVRAM / SMC Reset (no change)
Alternate Cables (no change)
Alternate Monitors (no change)
Alternate Computers running OS X 10.8.5 via HDMI wiring schema as before (image on both monitors)
I'm no GENIUS, but I do have a modecum of experience with troubleshooting this kind of stuff and I am 100% confident that OS X 10.9.3 has caused this problem. Now, who wants to tell me how to fix it before my warranty runs out in 45 days.
Mac mini, OS X Mavericks (10.9.3), 2 x Mac Mini's Same Problem
