Yep, it depends on your devices but not all devices work without flashing the Titan Ridge card. CaseySJ's Z390 thread has a ton of thunderbolt info

Non-flash method
- Guide (Section E.7) by @kgp
- (Attached SSDT below, SSDT-DTGP.aml method is already in my BASE-EFI)

Flash method (Thunderbolt Bus)
- More info about why it may be necessary here (Section: Thunderbolt Bus Activation)

Upgraded to Catalina 10.15.7 (Open Core 0.6.1) ON M2 drive and Big Sur Beta (Open Core 0.6.1) on SSD.
Both installations went without issues and very smoothly. Big Sur is a pleasure to use on my 42" Vizio.

Thanks to all the forum leaders!!!

Try this EFI, not sure why you have SSDT-AWAC and RTC0. It's usually one or the other. Also you had CustomMemory set to Yes but no memory mapping so i disabled it.

thanks so much.

but still no go...

may be i need to give up...

Just curious to see if anyone has updated their board to a BIOS with Resizeable BAR support yet?

I realise that this is likely a fringe case and very few have any want or need for it, and obviously not expecting any benefit at all in MacOS, but I know a few here have 6800's or like me an AMD and an RTX 30 series and it would be nice to have Resizeable BAR available in Windows without breaking MacOS.

I tried the latest MSI BIOS for the X299 Pro and couldn't get it to boot properly, it would simply reboot the machine just at the point it would normally present me with the MacOS desktop and the login window - even when disabling the resizable BAR feature.

Haven't done any real troubleshooting and I'm not really after any support assistance at this point, just curious if anyone else has played with this yet?

Its quite possible that my failure to boot is completely unrelated to the feature anyway and really I need to update the BIOS re-dump the DSDT in Windows and check for other changes that could affect my SSDT's before drawing any conclusions. Hoping there are other changes afoot in the MSI BIOS - with any luck native NVRAM... I can keep dreaming :)

on the Asus X299 Prime Deluxe it seems that the new Bios 3403 (with BAR-Support) broke the TB-USB (GB Titan-Ridge 1.0)... Catalina boots but you can't use TB-USB on Big Sur you get random freezes... any suggestions / help or informations ? @CaseySJ @djlild7hina

Thats my suspicion with the MSI board - perhaps plenty of other changes rather than that one specifically that's not working with my system. I will at some point go back to the new BIOS and do some proper investigation. I don't have TB unfortunately so can't comment on that yet. Keep us posted if you get working on the new BIOS :thumbup:

We've seen this problem on other board as well. The only solution we're aware of is to reinstall the previous BIOS.

Do not give up

I purchased ASUS Prime X299 Deluxe II just a few days ago
For Thunderbolt 3 Support (I replaced my old Asus Rampage VI Apex)

And my previous installation just came up without a problem
With Thunderbolt 3 also (in retrospect) there was no problem
All you have to do is install Windows 10 on another drive and install the drivers for Thunderbolt 3

And next time you turn on your hackintosh
You will see that your thunderbolt is working

I'll send you my efi as it is
Do not forget to create a serial number etc.
and TSCAdjustReset is for 18 core! (place yours)
