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