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

@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.

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

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).

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?

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?

• When attaching or detaching the 8-pin SOIC clip to the Winbond chip, a nearby surface mount device was accidentally dislodged.
• To avoid this problem, the following guidelines are absolutely and unequivocally critical:
  • You must have excellent near-sightedness.
    • If you wear corrective lenses to see distant objects, remove those lenses and use your natural near-sightedness.
    • If you are far sighted and need corrective lenses to view nearby objects, determine whether you can see objects clearly when they are only 2 inches away from your eyes. If you cannot do this, please enlist the help of someone who can.
  • When attaching and detaching the spring-loaded 8-pin SOIC clip to the Winbond chip, use very steady hands and gentle motions. Position the clip directly over the chip and move it up-and-down over the chip. Never move it side-to-side otherwise nearby components can be hit and dislodged.

Can it be undone? Or could I also brick it for good?

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

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".
