Thunderbolt problems with Windows 8

TIP: Fix for Thunderbolt problem with Windows 8 in Boot Camp

Boot Camp users who updated Windows 7 to Windows 8 may find that a Mac booted with Windows 8 does not recognize Thunderbolt . According to a new Apple tech article, the problem is an incompatibility with the Windows 8 Fast Boot feature (also called Fast Startup). The workaround is to disable Fast Boot using the Windows Control Panel. Here's how:

  1. In Windows 8, open the Control Panel. (You can move the mouse to the upper-right corner to activate the Charms bar, click the Settings icon, and then select Control Panel.)
  2. Select Hardware and Sound.
  3. Under Power Options, choose Change What the Power Buttons Do.
  4. Under Shutdown Settings, uncheck the Turn On Fast Startup. Checkbox.
  5. Click Save and then restart the Mac back into Windows.

After restart, Windows 8 will recognize Thunderbolt devices attached to the Mac.

Thunderbolt Ethernet adapter is not working Windows 8. Windows 8 in the Device Manager doesn't even seem to recognize when I plug in my Thunderbolt adapter.

13-inch MacBook Pro cannot boot Windows 8

A reader points out that the MacBook Pro 13-inch Mid-2010 cannot be booted with Windows 8 using the new Boot Camp 5 released last week, despite another article indicating support for that model. Apple's Windows 8 FAQ, which we quoted on Friday, lists the MacBook Pro, Mid 2010 or newer, as a being able to boot from Windows 8 with Boot Camp 5. Article HT5634, however, states that the 13" MacBook Pro from Mid 2010 does not run Windows 8.

Brant Stalzer brought this to our attention:

I have Windows 8 64-bit running on my mid-2010 MacBook Pro 13-inch, minus various driver-related features. I try to use Boot Camp Assistant 5.0.2, but I get a fail message that only Windows 7 can be installed on my hardware. I tried a couple ways to install/update drivers using the 5.0.5033 support files, but nothing seems to be helping.

I also see varying info on the Apple site. I have Boot Camp Assistant, etc., on my MacBook Pro, but Apple has Windows 8-64 unchecked for support on this page: But other Apple pages indicate that mid-2010 MacBook Pro 13's should be supported.

The Mac models that support Windows 8 via Boot Camp 5 are as follows:
  • MacBook Air, Mid 2011 or newer
  • MacBook Pro, Mid 2010 or newer, except for the 13" inch model
  • Mac Pro, Early 2009 or newer
  • Mac Mini, Mid 2011 or newer
  • iMac, 27-inch, Mid 2010 or Mid 2011 or newer (the 21" Mid 2010 does not support Windows 8)

Reader reports Windows 8 OK after a partition format

Windows 8 64-bit works with the Retina MacBook Pro. I had to wipe my 32-bit partition I had installed and start over.

TIP: USB devices can prevent Windows installing on Macs

Windows may boot a Mac to a black screen during or after installation if you had a USB device connected to the Mac during a Boot Camp installation procedure. According to a newly updated Apple tech document, this can occur if you installed Windows from a USB optical drive or USB flash drive, and had another USB device connected to the Mac. This does not include a USB keyboard and mouse.

The workaround is to reinstall Windows without the extra USB devices attached: leave only the USB device containing the Windows installer, and a keyboard and mouse if needed. First, restart the Mac by holding the Power button. Hold the Option key down and select the Windows installation media when its icon appears on the screen.

TIP: Update MacBook Air firmware to install Windows 8

Apple reports that in order to run Windows 8 with Boot Camp 5 on the MacBook Air (Mid 2012), this Mac model needs the MacBook Air EFI Firmware Update 2.6 or later. If Firmware 2.6 or later is not installed, Windows 8 may not start or start with low-resolution graphics. As reported last week, there are other particular Mac models that also have issues with Windows 8 and Boot Camp.

If you've had this problem and tried to boot Windows and it just stopped, you'll have to turn off the MacBook Air by holding the Power button. Start up again while holding the Option key and then select the Mac partition when it appears to boot from OS X. You can find the firmware update by selecting Software Update in the Apple menu.
