Hello @synnys,

MOTU devices haven't given us much of a problem. Some questions before you consider flashing the firmware:
  • Is the MOTU failing to connect in Catalina, in Monterey, or both?
  • Have you tried enabling AppleVTD?
  • Have you tried setting BIOS --> Thunderbolt --> Thunderbolt Boot Support to Boot Once? Then reboot with MOTU already connected prior to macOS startup.
  • Which version of BIOS is installed on your Z390 Designare?
Hi Casey,

It works fine in Catalina (even hot swappable through the Apple TB2->TB3 dongle), and has worked fine in all OS'es leading up to Catalina. Big Sur messed things up and didn't work for me, and neither does Monterey.

I just tried enabling AppleVTD according to these instructions:


Steps:

  • BIOS --> Enable VT-d
  • OpenCore --> Uncheck DisableIoMapper from Kernel Quirks
  • OpenCore --> Remove dart=0 from boot-args if it exists
  • OpenCore --> Add SSDT-DMAR.aml (attached) to ACPI --> Add section as shown
  • OpenCore --> Delete DMAR from ACPI --> Delete section as shown
  • Reboot

I also set Thunderbolt Boot Support to Boot Once and I'm running F9i as a BIOS version.
Also tried Thunderbolt VTd base security (both enabled and disabled)
Makes no difference unfortunately.

Cheers

When you say « USB-C devices do not hot-plug on Thunderbolt ports », you mean they are working when you plug them once booted or missing completely like on f9j? If they work not hot-plugged, I think the behavior was the same with old working USB-C on TB3 Bios versions if I recall correctly…
...
Correct. USB-C devices simply do not work on the two Thunderbolt ports, but they will work if connected via a Thunderbolt dock.

Because it worked in Catalina, it means Thunderbolt Bus (i.e. flashing the firmware) will most likely not make a difference.

Suggestion:
  • With the MOTU connected (in Monterey), run IORegistryExplorer and scroll (not 'search') down to RP05 and post a screenshot of that section such that the DSB1 and DSB4 devices trees are fully visible.

Happy New Year everyone!

As promised, I've installed BIOS F9 (capsule BIOS) on my Z390 Designare and found no issues so far. Some notes:
  • Once this BIOS is installed, we cannot install any previous BIOS.
  • Sleep, wake, restart, shutdown all work under macOS Monterey.
  • USB-C devices do not hot-plug on Thunderbolt ports.

Good to hear that the F9 BIOS allows for running MacOS Monterey at least.

But my objective is to keep running older versions of MacOS : Sierra / High Sierra / Mojave / Catalina (still using Clover). So I don't think I will update any time soon (currently on F7).

Hi all! I had a CPU error and to replace that I sent my z390 Designare Mobo along with CPU to service center. It seems they have updated the BIOS to F9. So when I installed Big Sur I am facing Random freezes and disconnection of my ASUS XG-C100 network Card. Should I go to Mojave or Catalina or is there any work around on this?

Thank you

Several comments:
  • BIOS version can be checked by going into BIOS Setup. The exact version will be shown.
  • Did you install Big Sur recently? Before or after the motherboard came back from service?
    • Was Big Sur stable at any time? Did the freezes occur recently?
    • Have all software been updated for Big Sur?
    • Some drivers (kexts) are not compatible and need to be updated or removed. A list of drivers can be found by listing the /Library/Extensions folder.
  • Do you have Mojave or Catalina still installed on a bootable backup disk? If so, try booting it to see if the system is stable.

I was using Mojave with F8. Yesterday I got the Mobo back and did a fresh install. Anyway I had to update as most of my apps (updates) will not work with mojave. Later only I saw your post about F9 and monterey, so now I am installing Monterey.

Completed Monterey installation, so far so good. The problems I am facing are,

1. Intel network ports are not recognising one of my network switch. It works perfectly with windows 10.
2.Wifi(builtin Intel) is getting connected but after a minute I am losing internet connection.

I have a z590 vision D, it also has these two probelms.
By the way I am using oc 0.7.6 for z390 and oc 0.7.4 for z590.( Both frm hackingdrom).

That pci137a,8@0 is my MOTU, because when I switched thunderbolt ports (and had to reboot) it was under DSB4@4 as seen below:

And this is what it looks like when I boot in to Catalina:

Driver is installed and extension is not blocked...
