Comments
I got a cheap second-hand Apple Thunderbolt Display (27"), and struggled to connect it to my NUC. After a lot of trial and error, I managed to figure out how to enable Thunderbolt and make it work.
All this was possible using amazing work of OSY86 (Specifically ThunderboltPatcher and HaC-Mini project targeting Intel NUC Hades Canyon (NUC8i7HNK/NUC8i7HVK), which served as a reference for my work)
The build
Installing the native Wifi + BT card:
We're using the M.2 slot for installing a chinese adapter for native Apple Wifi + Bt card. The Wifi card is using the PCI-express port of NVME, and Bluetooth is connected using on-board usb header.

BIOS Settings
I upgraded the BIOS to the latest v83.
Disabled CEC, VT-D, Onboard bluetooth and wireless, Infrared. Thunderbolt mode is set to "Legacy".
In order to make the system boot without attaching HDMI display, "Legacy Boot" needs to be enabled.
For your convenience, I'm attaching a customized BIOS - this is the default NUC INTEL BIOS v83 with all config options already set + Apple Logo instead of default Intel NUC Logo. Put the bios on FAT formatted USB disk, boot and select F7. Then flash the BIOS.
BIOS was modified using Intel Integrator Toolkit

Code:
ITK6.efi –b –x custom.bio –ib BE0083.bio –is –ic –id –il applelogo.jpg
OpenCore
I followed the
OpenCore Laptop Guide for my Coffee Lake CPU
Choosing MacBookPro15,2 because it is very close to my build.
Please change your Serial/UUID/Board Serial in both EFI-flash/config.plist and EFI-native/config.plist using the following guide (
https://dortania.github.io/OpenCore-Install-Guide/config.plist/#creating-your-config-plist)
- You will need to use GenSMBIOS.command -> Generate SMBIOS -> MacBookPro15,2
Flashing the Thunderbolt Firmware
In order to enable Thunderbolt natively in OS X, you need to modify the firmware (and make it similar to real Mac).
There are 2 EFI folders attached to this post:
EFI-flash - this is used for backing up the current firmware + modifying it
EFI-native - this is used to run the modified firmware
Caution: after you flash the firmware, thunderbolt hot-plug will not work in Windows. It is possible to un-flash the firmware (return it to original settings) if you require Windows functionality.
Flashing Thunderbolt firmware
Step 1 - Enable Thunderbolt:
Replace your EFI folder with contents of EFI-flash.
Do not connect anything to Thunderbolt port on the NUC
Power off the NUC and disconnect the power cable for 10 seconds
Power on the NUC and boot MacOS
Open System Report (Apple logo -> About This Mac -> System Report)
Under Thunderbolt, you should see the controller.
Step 2 - Backup Current Firmware:
Copy ThunderboltPatcher folder to your computer (for more information about ThunderboltPatcher, go to
https://github.com/osy86/ThunderboltPatcher)
This should only be done once. This is a safety measure - in case flashing fails, you will be able to restore the firmware using external programmer
You should see something like this:
Code:
/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/RP05@1C,4/IOPP/UPSB@0/IOPP/DSB0@0/IOPP/NHI0@0/AppleThunderboltHAL/AppleThunderboltNHIType3/IOThunderboltController/IOThunderboltPort@5/IOThunderboltSwitchType3/IOThunderboltIECSNub/AppleHPMIECS/AppleHPMDevice@0
Address : 0x00000000
PID : 0x2831454341
UID : 10AFF80F-EDF3-75BB-384D-42D28F2D5FCD
Version :
Build : c21bda84555465022d578161e3aecb523fe75643_12082017
Device : TPS65982 HW0011 FW0001.12.07 ZTBT1
Perform backup:
Code:
sudo ./tbpatch dump -s 0x100000 -f backup.bin
This should take about 10-15 minutes to finish.
After it's done, copy the file somewhere safe / email it to yourself.
Step 3 - Modify the firmware:
This patches the firmware on your NUC.
Code:
sudo ./tbpatch patch -f nuc8.plist
This should take about a minute
Step 4 - Change the EFI folder to native:
Rename the EFI folder on your EFI volume to EFI-flash
Copy EFI-native and rename it to EFI
Eject EFI volume
Power off the NUC and remove the power cable for 10 seconds
Power the NUC again - it should boot and your Thunderbolt controller should be fully functional.
Revert to original firmware:
If you want to un-flash the controller (For Windows hot-plug), you can restore it to original settings.
In order to revert to original firmware, you should run the following:
Code:
sudo ./tbpatch restore -f nuc8.plist
After that, power off, remove the power, wait 10 seconds and boot.
Troubleshooting:
If your system fails to recognize Thunderbolt on flashed/unflashed firmware, try to remove power for 10 seconds. This can happen after booting to other OS (Windows/Linux)
Conclusion
I got working iMessage/Facetime/iCloud, all USB ports, Bluetooth, Wifi, Airdrop + Thunderbolt hot-plug + working Thunderbolt display. Additional HDMI display also works (hot-pluggable)
Sleep is disabled on my NUC, but it should also work with the modified firmware (not tested)
All devices on Thunderbolt Display also work (camera, microphone, speakers + USB ports)
I also have Thunderbolt docking station, and everything on it works + daisy chaining Apple Thunderbolt Display works as well.
P.S. This should also work on NUC8i7B* and NUC8i3B* (not tested)
