Q: Windows 10 Fails To Shut Down my Late 2013 Mac Pro

I upgraded Windows 8.1 installed under Bootcamp  on my Late 2013 Mac Pro to Windows 10 and installed the latest Bootcamp support software for Windows 10 recently provided by Apple.  Both the upgrade and the installation of the Bootcamp support software occurred with no errors and both went fully to completion.  Windows 10 runs fine on my Late 2013 Mac Pro and all is well until I try to either shut down or restart this Mac Pro.  When I select Shutdown or restart in Windows 10 all of my external drives and other USB devices shut down properly and my monitor turns off as it should.  However, my Late 2013 Mac Pro remains on as indicated by yhe white power light on the rear remaining lighted and I have to press and hold the power button for about 10 seconds to turn off the computer, and then press it again to restart in OS X.  This occurs only when trying to restart or shutdown in Windows 10.  When I am using OS X, I have no problems restarting or shutting down this system.  I also have Windows 10 running under Parallels 10 and I have no problem in Parallels shutting down or restarting Windows 10.  The failure to shutdown properly only occurs when running Windows 10 via Bootcamp.

 

I would be most appreciative of any help that you can provide to me, and I thank you in advance for your help.

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

    Sorry for not making clear - I had exactly same issue as you described as well  - Mac Pro failed to shut down unless one graphic card is disabled or Cross Fire is disabled (same thing really). After recent Bootcmap update problem is fixed. Try to update your Bootcamp and see what happens

    Ahhh...gotcha. Good call !  I had forgotten all about the apple updater and thought I was stuck since I don't have OSX installed, just Windows 10.

     

    Just ran the updater and voila, can keep crossfire enabled.

     

     

    Cheers!

    Thank you brianrogers!!! Works like a charm! The Mac Pro at work took some 5 minutes to the "chime" when booting from windows 10 home to Mac OS X, after disabling the AMD crossFireX it only takes a couple of seconds.

     

    Pitty that neither AMD nor Apple have addressed this and it is more than 8 months since the original post.

     

    Apple needs just to face the fact that people buy apple machines and use them with Windows. Using only Mac OS all the time is like being locked in the holiday resort all year round ... it might be nice at first but it's certainly not the best place to do engineering work ....

    If I was at Apple I would see this as a good business oportunity to eat into PC hardware market share. ... Maybe that is why I am not at Apple...
