Summary:
When waking the Mac up from sleep, it will show a black screen and nothing else (the Mac needs to be asleep for a few minutes for this to happen). Once in the black screen, the only way that I can actually use the Mac again is to do a hard shutdown and boot again.

Steps to Reproduce:
Put the mac to sleep
Wait a few minutes
Try to interact with the mac again

Expected Results:
Mac should wakeup as it always did.

Actual Results:
Black screen (display is turned on and backlit but the screen content is black). The fans will usually be running at full speed as well.

Version:
10.12 Beta (16A239j)
