But there is NO Thunderbolt Firmware Update Tool under the Utility section of the website for the GA-Z270X-UD5, in contrast to the GA-Z170X-UD5 TH. That's why I don't think I should ever need to "activate" Thunderbolt on the Z270 board. I may still try to install Windows and then the Thunderbolt drivers to see if such a step is still necessary, but it will have to be later.
To be clear, do you have the GA-Z270X-UD5 (one Thunderbolt 3/USB-C port) or the GA-Z270X-UD5 TH (one back panel TH3/USB-C port, and one TH3 motherboard header)?
I ask because I have the latter board. Thunderbolt does work, to the extent that my Apple Thunderbolt Display operates, along with its USB hub devices (FaceTime camera/mic) and other port features (Ethernet, Firewire, etc). However, I have some stability issues which I can't pin 100% on the Thunderbolt display being connected, but seem related.
Note: I installed the Thunderbolt drivers in Windows 10 before attempting the Sierra install. However, other than various DSDT patches I had to make to get my iGPU and dGPU working simultaneously for dual monitor support, I didn't have to do anything else in OS X to get the onboard Thunderbolt working.
