Some good info this morning from Videocardz.com on AMD RDNA2 Raden PRO. AMD PRO cards mean supported drivers, presumably for Mac.

This shows that Thunderbolt hot plug is enabled, but the MOTU drivers are not recognizing the device. It's possible that the new drivers require Thunderbolt Bus. We will have to flash the firmware for that, but it incurs some risk of damage and does not guarantee that the drivers will work. It would be the next logical step, but one that should be carefully considered. All of the details are in Section 8 of the Quick Reference spoiler at the top of Post 1. We should use a 3.3V USB CH341a reader/writer (link in Section 8.2.4 of Quick Reference spoiler).@CaseySJ I updated this post and it’s attachments.
The "boot once" didn't work.
the PCI137a,8 is my motu interface, it says there's no drivers installed, but they are installed. As can be seen in the screenshot. I also allowed the system extension to load in the security and privacy window.
I attached my IOreg and the screenshots below.
This is a bit of a long shot, but try each of the highlighted boot arguments one by one:Dear Forum Members,
I have question regarding the Login Screen and Desktop Screen resolution difference.
I am running lates OC and latest mac os (thanks to @CaseySJ and @Inqnuam).
The problem is nothing new. (I have the same problem from the first day of build but, I just started to think addressing that.)
I have an RX 580 graphics card connected to 4K monitor via Display Port.
In Opencore picker I have no problem, it is 4K. But the login screen is Full HD, and when I enter my passwd, it changes to 4K again.
I have enabled the root user and changed the resolution.
Do any of you have any solution ?
Best
I wonder if anyone else is already so far, since the drivers were only released yesterday.This shows that Thunderbolt hot plug is enabled, but the MOTU drivers are not recognizing the device.

However, I wonder if it's better to revert back to Catalina for the time being.
Is anyone successfully using a Thunderbolt MOTU audio interface with Big Sur?
While most folks have flashed the controller successfully, there have been a few accidents that have left the board permanently damaged. These accidents all had one thing in common:I wonder if anyone else is already so far, since the drivers were only released yesterday.
Could you elaborate a bit on the risks involved flashing the firmware?
Yes it can certainly be undone. We first extract three copies of the original firmware, compare their checksums and then flash the modified version. We can flash any of the three copies of the original firmware back to the chip at any time.Can it be undone? Or could I also brick it for good?
After installing the drivers you need to give permissions.I came from Clover 10.15.7, and, since MOTU finally released their Big Sur drivers yesterday, I decided to start fresh.
BIOS: F9i (unmod'ed)
OC: 0.6.8
OS: 11.2.3
EFI: the latest 068 from @CaseySJ
config.plist: generated using https://hackindrom.zapto.org/
Now the system works fine so far, except for Thunderbolt. Which was working perfectly fine on 10.15.7
I've tried method 1 from this post: https://www.tonymacx86.com/threads/...700k-amd-rx-580.267551/page-1616#post-2086547
Not sure if I missed something here...
Help would be much appreciated.
Cheers

Yeah did that. Didn’t work.After installing the drivers you need to give permissions.
Try checking on System Preferences > Security & Privacy > click "Allow".
If you do not find any requests, try uninstalling the Motu drivers, reinstall them and check again on "Security & Privacy".
