Headless Mac mini AirPlay Problems
I was running into an issue with my Mac mini (2011) running Mountain Lion when trying to run AirPlay mirroring to Apple TV. I figure I should share this in case people are having similar issues.
The Mac mini is a headless unit that I Share Screen into from my MBP or iOS devices. When I tried to run AirPlay mirroring to the Apple TV after installing Mountain Lion, the mirrored image would result in a garbled pink screen. It seemed like no matter what I did (changed network settings, display settings) the same thing kept happening. It wasn't until I tried plugging a monitor into the headless Mac mini that AirPlay mirroring suddenly worked. Unfortunately - I have to keep the monitor plugged in for this to work, thus negating the whole benefit of running a headless machine. Hopefully this is something that can be taken note of and perhaps fixed in a future version of ML. Anyone know how I might be able to submit this as a proper bug report?
I tried this on both a 2nd and 3rd gen Apple TV with the same results.
