Thoughts on this one? So the machine sleeps fine. It seems the problem occurs from this symptom: the HDMI is hooked up to a 4k TV. If it sleeps and I come back 24hrs later and turn on the tv and move mouse or keyboard it wakes. If I come back 24hrs later but someone has used the tv on a different input for example HDMI 2 than it wakes from sleep, I can see the HDD indicator light but the video does not show up on the screen.
I am using the iGPU headless btw. Help? Should I turn off iGPU? Using iMacPro SMBIOS.
Have tried unplugging and replugging HDMI no luck. Haven't tried plugging into iGPU though
Thoughts?
