Every time I try to shutdown or restart my nMac Pro in Windows 10 it goes to a black screen and hangs. I have to do a force shut down by holding the power button.

Does anyone know how to fix this issue?

No one else is having this issue?

You can check the Windows event logs if you see something. Other than that ... I don't know.

Classic:

- Install clean, test
- Install drivers, test
- Install whatever, test
- and so on

good luck !

After the pain in the ass that it was getting Windows 10 with graphic drivers working on the new Mac Pro, I'd be supremely pissed if I have to do a clean install.

I am having the exact same problem with my 2013 nMac Pro. This occurred with both an upgrade from 8.1 to 10 and with a fresh install to 10. Apple probably has to update the Boot camp software for the nMac Pro.

I believe I actually found the solution: It happens with CrossfireX is enabled in CCC. If I disable it I can restart just fine.

This is an old problem and is usually related to having multiple devices that are sharing a background process, for example two graphics chips or two storage devices.

Thanks for finding this, and I'll have to try it. If it works, I guess the only thing that will fix it is a driver update. Unfortunately, AMD and Apple are not too good about releasing regular new windows drivers

I just tried disabling CrossfireX and the computer rebooted fine. I guess we'll have to wait for Apple to release new drivers.

I have reported this to Apple and suggest that anyone else with the same problem also report it.
