Just checked this morning, the black bar at the top of the screen when using screen sharing for a mac mini has now been fixed in 10.10.4. Does this mean the GPU has been activated in headless mode?

i'd love to verify that. Any idea on how to check the GPU usage? I could screenshare/remote login into my headless mac mini and compare the usage to when it is connected to a monitor.

I'll be updating to 10.10.4 on my mini server this coming weekend. I'll post again with my observations.

This what I see on 10.10.4 in headless mode, I'm not sure if that means the GPU is enabled. Do others who have 10.10.3 see the same?

I don't think this works - I keep an HDMI fit-Headless dongle in my headless 2012 mini, so I tried removing it after upgrading to 10.10.4. Upon removing it initially, resolution stayed at 1080p (when screen sharing to a 1080p display). However, after logging out or rebooting the max resolution is limited, with black bars to either side of the desktop. I'll keep using the dongle...

Just an update to this.

With the headless mac mini adapter I saw no improvement to graphics performance. It seems the GPU was enabled before without the adapter. In fact adding the adapter bought back the black bar at the top of the screen. So it seems the GPU is enabled in 10.10.4. I am using the app, 'display menu', however.

We still see the delays on our Mac minis even after 10.10.4 update. (Looking to do some more testing with El Cap now that the public beta is out.)

We still use the HDMI adapters and they work well. (And we prefer them over the newertech adapters because they don't take up a Thunderbolt port.)
