Stork's Thunderball II Build: ASUS ProArt Z490 Creator (Thunderbolt 3) - i5-10400 - RX 580

it is a display. I have a two apple displays and want to use it on my new motherboard. I read that @CaseySJ has flashed the z390 and z490 motherboards he uses ... I hope he sees this post :) He knows the answer for sure)
Nobody has flashed this board yet as far as I'm aware. It is generally not recommended to use thunderbolt displays with hackinosh, very random success rates. CaseyJ has provided extensive info on this if you search his threads.

Please let us know if you decide to flash the MB and how it went.

Yesterday I flashed this board, but Apple Thunderbolt not working yet... I see Thunderbolt Bus and Port 1, Port 2, but "not connected", if device not connected. After reboot, and, when display connected, I see something different. Maybe my EFI is not configured. If somebody share config, I'll try with another EFI.
I was take this:
Asus ThunderboltEX-3 TR (Titan Ridge) ASUS-ThunderboltEX-3-TR-NVM56-MOD1-CaseySJ.bin .
 
So, I won. BIOS settings + ROM flashing saved my life.
Now my Apple TB display have a picture in macOS after bootscreen.

Nice. Can you see BIOS menu and OpenCore Boot menu? Please provide some details of how you flashed it; e.g., where the chip is located.

The chip is as it is in Gigabyte Z490 Vision D which you can see on back side, near the TB3 ports.
I have a friend who is engineer for notebook motherboard repair, and he helped me to flash this chip.
OpenCore config is not something unusual, and, if you have bootable macOS and Thunderbolt hot-plug, you have all needing for work Thunderbolt bus.
In the BIOS I followed @CaseySJ instructions in his last micro-guide OpenCore 0.7.2
I Enabled VT-d, and I enabled SR-IOV. (maybe it was not a necessary)
I enabled iGPU. (It was disabled.)
Wndows 10 support on "Enable". not "Enable + RPD3"
Boot support "Enable". (In Gigabyte I used Boot once)
Numeric parameters in Thunderbolt options without changes.
 
This is fine, I assume this is happening because you are not using the Thunderbolt Hot Swap SSDT that @Stork provided. You'll have to redo the map if you decided to use his SSDT later. I need to update the guide since he provided an updated thunderbolt guide.

Otherwise your map is looking perfect!
Thanks @ctek

Not sure if I am missing the post with the hot swap SSDT. I took the SSDT file from the original post when I built my system in July. I also checked Post #198 as mentioned in the original post June 27 update, but it only refers to Ethernet fix.
 
Just upgraded my hack to this board and an i9 10900 from my older Z170 WS/i7 6700K (running Catalina).

I haven't used OpenCore before (was on Clover prior) so that was all new for me.
Updated BIOS to latest on site available yesterday. I got Big Sur 11.5.2 running (started with 11.2.3 then USBMapped and upgraded following mapping instructions from @ctek - thanks!) - Ethernet and Thunderbolt both working (waited until the upgrade to 11.5.2 to do that).

Thanks to everyone in this thread (@Stork, etc.). I wouldn't have got there with just the Dortania guide alone for sure.

Sorry for the late reply, been busy with work. I’m a bit lost as to why this is happening, although it shouldn’t cause any problems. Could you tell us your Thunderbolt settings in BIOS?

The reason I mentioned about the hot swap SSDT is that is renamed the TB controller which would make a lot of sense. But, if you have that SSDT enabled, then it should look the same as mine unless something happened in a bios update. I’ll look into it more when I have time but it shouldn’t cause any problems.
 
Is there any way to install it on Mojave OS?
It works fine on Catalina OS.
It won't even boot in Mojave.

Yes. I was running Mojave, then Catalina, and now Big Sur.

In order to better help you, please post your procedure. Did you see the spoiler in the first post for Mojave?
