Windows 10 Fails To Shut Down my Late 2013 Mac Pro

Can you check Device Manager for any missing drivers? Are you able to successfully switch between OS X and Windows using System Preferences -> Startup Disk and Control Panel -> System -> Bootcamp properly?

Hi Tom,

I'm seeing the same thing on my 2013 Mac Pro. I have done some research so far, but not found a solution. I also have the hang when rebooting (hangs with screens off), and sleep (doesn't wake) in Windows 10.

Some information:

• After upgrading from Windows 8.1 to Windows 10 (using Bootcamp 5 Build 5640, which was not supported in Windows 10), no proper graphics drivers were installed, but no problems rebooting / shutting down.
• After upgrading to Bootcamp 6, the above problems occur (consistently).
• Uninstalling all Bootcamp 6 drivers from the control panel, the problem goes away.
• A clean install of Windows 10 with Bootcamp 6 (so no upgrading of Windows or Bootcamp drivers) has the same problems.
• Resetting the PRAM and the SMC controller doesn't help.

So the culprit is probably one of the Bootcamp 6 drivers, but I cannot really be asked to bisect all the drivers to figure out which one is the culprit.

I have contacted AppleCare and they have escalated the case. It might be worthwhile contacting them as well and mentioning the case number 861580451 so they have more data points.

Hi TomWheel and [maven]

Same here!

I'm using Windows 10 and Bootcamp 6 driver on my Mac Pro Late 2013 with FirePro D500 GPU.

My machine cannot restart/shutdown. When I try it I see everything is off, exclude power light and fans.

So I have tested GPU driver and now I know exactly this problem is about GPU driver.

You need open AMD FirePro Control Center ---> Performance --- > AMD CrossFireX.

Just Disable AMD CrossFireX and the machine can be restart/shutdown normal.

I have chat with some guys on the Apple Chat Support and let them know.

Now I hope they will update Bootcamp soon.

PS: sorry, my english not good

Hi Tom

Thank you for fast responsive and let me know.

I think this dual GPU will work fine with AMD CrossFireX mode but the Bootcamp 6 driver have some bugs.

Because on Windows 8.1 I see it's not happened with CrossFireX mode enabled.

So I think we need to report this problems to Apple's Engineer Team and let them know to fix it.

Anyway... I hope Apple will fix it soon.

Yes, this very much a work-around, not a fix, as it nearly halves GPU power in Windows. As it is the default, one would've hoped that testing would've caught that sort of bug.

In any case, many thanks for the hint. At least I don't have to get up to hold the power button whenever I need to restart... 😉

Same for me FirePro D700, Mac pro 2013 I hope apple will fix this.

Yes, same for me as well, FiraPro D300, Mac Pro (late 2013). Total ignorance from AMD to support hi-end user. I've got a response from AMD forum when I raised this issue - "You will need to contact Applecare or Bootcamp support for help with this issue." Apple will say we do not support Windows, on MAC OSX there is no problems - so here we have it.

Same problem for my Mac Pro with D700, and thx for the temporary fix.

However, considering the ultra slow update of graphic drivers, I don't expect complete solution by Apple or AMD 😟👿

PLEASE fix this Apple!!! Who wants a $6K computer that can't even use the hardware in Windows 10!!!! D700, 6-Core, MacPro 2013

Nvidia has no problem releasing drivers that have NOTHING to do with BootCamp! AMD NOT having "unified" drivers is an abortion of development these days!

BTW, BootCamp 6.0 drivers on Windows 8.1 (with Crossfire enabled) causes NO problems at all. Couldn't be happier with Windows 8.1...but what I WANT is to be able to upgrade to Windows 10 without a problem of restarting the computer!

Has anyone confirmed that they are running with 8 (bpp) Bits Per Pixel? Seems that the new default AMD with BootCamp 6.0 is to use 10 bits per pixel...which if your monitor supports it WILL cause all types of problems in games etc. Can you please make sure that this is set correctly for each monitor you have and retry?

Tom,

Same here, 8 cores, D 700,

The problem seems to be when you upgrade to Windows 10, as Microsoft has opted for a compulsory update download and automatic install of all softwares updates, they feel should be on your machine,

The glitches appears on the apple machine as AMD Driver Auto detect seems to think as you have a D700 and Windows 10 it needs to install the latest (June 15) AMD Driver made for a Windows computer, when this driver install in the background without you knowing it, the troubles start,

However if you are patient and wait 30 minutes or so the program shut down by itself,

Here is a solution that work for me: went to the AMD website, Drivers Download page, then download on your window side (Bootcamp C) the driver made specially for Apple BootCamp this is an older one (December 13 0r so) then open and instead of install click on remove all AMD drivers from this computer, after this is finished use you USB fat 32 to reinstall BootCamp 6 from Apple it will say repair BootCamp click and voila back to normal

But this problem is bound to happen again to stop it:

How to temporarily prevent a Windows or driver update from reinstalling in Windows 10

You have to download a program that allow to do this: " wushowhide.diagcab" launch and follow instructions it allows you to stop the updates you don't want to install and prevent any AMD drivers to install themselves automatically, the only AMD drivers that work with Apple hardware and Windows 10 are from BootCamp 6, the old AMD drivers made specially for Apple BootCamp work well with Windows 8.1

This is how I solved the 30 minutes hangup, but others solutions may work better when all the bugs are ironed out.
