There you go.
I now have a working VRS8 and it didn't seem to break anything. Though that remains to be seen. No USB problems, but I already had a custom USBMap.kext.
I'm so happy! Thank you
@joevt !!! And thanks
@luckyal
I somehow missed the not dropping DMAR step because it wasn't on
@luckyal list. I'm sure it was in the discussion, but even though I've read this thread again and again, I somehow missed it. I actually had it on, because I read that having it might prevent some issues with Vt-d. In this case it caused an issue.
So
- Enable VT-d from BIOS (there's no VT-x setting in Gigabyte z390 BIOS to disable VT-x separately that I know of)
- Enable above 4G decoding from BIOS
- Remove dart=0 from Clover congig.plist (if you have it there)
- Don't drop DMAR table (again in the Clover config.plist)
No need to modify VRS8AudioDriver.kext.
I'm beyond elated!
