I did, I can see the TB port there but it does not work. He claims it works hot plug too, but it does not for me (even though I have same motherboard and used same EFI)
Weird... Hopefully someone will try same mobo soon

Ah, I had similar issues with USB. I ended up using a combination of bits from his config.plist and others from another thread on here. I ended up using the USBmap tool to create my own USBmap.kext. I got most of the ports I need working, the tricky one was the internal USB header for my Broadcom Wi-Fi/Bluetooth card (natively supported)

To get the 225 working.

1. Find out what the correct path is, in this case under RP05.

2. determine the address. Comes from the same picture. 1c,4 is the slot and 1c,4,0 the controller

3. because the 225 does not work, the device id is not correct. Therefore determine the Device Id. It's 15F3 - you see it on the right side, but the bytes are swapped.

4. the Device Id must be 15F2. Therefore in OC DeviceProperties, enter the new Device Id for the card. Note that the address has an additional 0.

5. create fake PCI Id file.

So from using this for a bit, it appears that even though the 225 comes up, it's not really that usable. It appears to be dropping packets (very brief disconnects)

Hopefully we'll get a proper driver soon. For now I'm having better results with this:

en0:
Card Type: AirPort Extreme (0x14E4, 0x111)
Firmware Version: Broadcom BCM43xx 1.0 (7.77.111.1 AirPortDriverBrcmNIC-1600.4)
Supported PHY Modes: 802.11 a/b/g/n/ac
Wake On Wireless: Supported
AirDrop: Supported
AirDrop Channel: 149
Auto Unlock: Supported
Status: Connected

Do you have this mobo? I have the F version. Is Catalina working? If so, could you post your EFI, please?

Yes, Catalina is working. Zipped Opencore folder is attached:

EDIT: Replaced zip after some more tweaks to iGPU. 3 black USB 2 ports above BIOS port and one front USB 3 are disabled to stay under the 15 port limit. I needed the onboard USB headers working for internal Bluetooth/Wi-Fi card. (custom mapped)

Decided to use the MSI MEG Z490I UNIFY mITX for my personal mobile usage.

Finally got around to benching this thing, looks pretty good vs 9900K: (stock settings, no overclock)
