I Am running macOS Sierra developer beta 2 and it's been working fine. But all the sudden when I try and wake it up it won't come out of sleep mode. I have to resort to hard booting it to fix the issue but once it goes back to sleep it does the same thing again. Any help would be much appreciate!
I should have uninstalled them one-at-a-time, but didn't ... BUT, once uninstalled, I am no longer having this issue.
Uninstalled Duet and I can now wake from sleep with no black screen. Thanks!
Same problem here, but I also unistalled Duet on my MacBook early 2015, things are back to normal again. Thanks!

MacBookPro 13 retina early 2015, stuck on black screen (backlight on, only black displayed and no mouse cursor) after waking up from sleep mode (either auto sleep or closing the screen).
For now I'm using Caffeine to prevent entering to sleep mode and shutdown the computer instead of just closing it.
FYI I hadn't DUET installed but Avatron AirDisplay.
The problem comes from 3rd party display drivers.
For AirDisplay, you can find an Unistall script in the "Applications/Utility" folder.
Fixed the wake-up black screen issue for me.
I have the same problem with my MacBook Pro Retina early 2015. I can login to my MacBook using my Apple Watch, but, screen stays black.
Right after installing first macOS Sierra Public Beta, the screen of my MacBook 2015 remained black. Only the backlight worked.
Then I did dthe second Beta update in order to ger rid of this bug.
When I put my MacBook to sleep mode, after attemt to wake it up, screen remained black again.
So this is not the solution to uninstal Duet.
Don't have any other similar Apps or display drivers installed.
We have to reopen the issue.
Third party Asus MB168B monitor drivers, or "Easy Link" were causing problems for me. The driver DMG from the Asus support site also contains an uninstaller.
It said that sometimes a driver gets left over. I had apparently installed Duet and the driver was left over in /Library/Extensions/ . I got rid of that and restarted, and the display would properly wake from sleep again.
Hi guys, thanks for your suggestions and glad it worked for most of you, but in my case, after strugglin for couple of hours now, still no solution. I've tried PRam reset, SMC reset for couple of times, booted to safe mode and did kextstats in terminal for any app drivers leftovers in kernel, but mac still boots to black screen. Mouse, brightness and volume controls are still visable. Funny thing is, Windows 10 boots normally which ****** me off the most. Round the Internet there are only 3 suggestions for solving this issue. Anybody got 4th?
4th? 5th? The people who have been lucky seem to have old kexts or duet.
Where can we get just the latest SMC or EFI drivers or any and all low level stuff? Doing a fresh install doesn't seem to overwrite..
read every blog/site/forum post google could find from 2012 to july 2017.
My issue is that I will get black screen on when wake up Mac if I closed my lid when using extend display before some times.
https://www.youtube.com/watch?v=COOUrXBAYjc I had a video posted up before, but I had some technical issues with the video.
After trying all of the reset procedures nothing worked. I watched the video and thought, this is stupid, no way this is what's causing the issue. It was so stupid I almost didn't try it. But I'm glad i did, it fixed it immediately!!!
Like Quick2Comment, I had tried all the reset options and had jumped through hoops over the last few days trying to solve this. I, too, tried GustavoAquino's solution and it worked...immediately...I still cannot quite believe it, but it worked for me. Thanks very much!
