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.
No need to modify VRS8AudioDriver.kext.
- 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)
I'm beyond elated!
Hey Guys...another success Story, at least on my Dell9020. The VRS8 is working flawlessly with the PCI Card installed.
Guess what, even with Dart=0 enabled. Vt-D is activated and i installed the alternative OSXAptiofix3Drv-64 to get it working.
Seems like the different Aptiofix managed something with the memory allocation at boot...
No luck on my X299 Board so far...we need a better driver. Joevt any suggestions for the x299 boards?!?!
Do you know by chance where I can find this to download and install?Fixes memory map created by AMI Aptio EFI. Booting OS X is impossible otherwise.
You have to installed it via CloverConfigurator or the Clover Installer in EFI/Clover/Drivers64UEFI
