    When my MacBook Pro 15" (Mid-2015) resumes from sleep by timeout or by opening the lid I will get a black screen (I can see the background light on the borders, so its not 100% black) and I can only hear a beep if I press a key, there is no way (that I know) to fix it, the only solution is to force a shutdown via pressing the Power button for 5-10 sec, very annoying, happens multiple times a day, any tip on how to fix it or deal with it, will be appreciated, thanks

    sysdiagnose is your friend;

    For what you describe, it may be useful to wait longer. Half an hour, maybe.

    Same issue for me. Any fixes/causes?

    Going to set the computer never to sleep for the time being.

    I too am experiencing this issue on my MacBook Pro 15" (Mid-2015), but not every time it goes to sleep. I ultimately just have to force power off the machine to get it back up.

    Hey guys, I think it has to do with the automatic graphic switching. I unchecked it in System Prefs -> Energy Saver and so far the issue hasnt come up again. I'm also on a mid-2015 15" MBP

    Let me know if that fixes it for you.

    Strike that, still having the same issue. Hopefully a fix comes with the next beta.
