As i Said, use Clover Configurator and the install Driver’s Guide tab and make sure to only use One aptiofix

I've been trying to enjoy my VRS8 in-between my business trips. I have to say, I really like the no-frills approach. I'm very impressed by the quality I'm getting from the unit. But good news aside, now I'm back at square one for the Z390 build I was doing for a musician friend of mine. The methods that worked on my ASUS Z370 Hero board are not effective on the Z390 Desgnare. @MyTosh, it appears that you have the master. Wondering how your config is set up and contents of your drivers64UEFI folder.

For the longest time I thought that VT-d was incompatible with macOS. Found this interesting bit on VT-d and MMU Memory Virtualization:

By default, requests for physically contiguous memory return memory that is contiguous only from the perspective of I/O devices, and may not be physically contiguous in RAM.

If the memory must be contiguous to the CPU as well, you must pass the kIOMemoryHostPhysicallyContiguous option to IOBufferMemoryDescriptor when you request the memory. As before, such requests can fail if no physically contiguous blocks are available.



I've spent the last few days trying to get VRS-8 going on the Z390 board similar to @MyTosh without any success.

hi luckyal...did you try a different aptiopfix? Asisaid, got it running on my dell with the OSXAptiofix3Drv-64.
Lets hope the V2 Driver will fix this issue...need that thing running on my x299 Workstation

I tried them all. Aptio OSXAptio, OSX2000, you name it. Nothing works with the Z390 board. I'm curios how @MyTosh was able to get his going.

Hey there,

I saw you referenced my earlier post regarding my Z390 Designare Build and getting the Quantum to work. All I did was follow CaseySJ's instructions. How can I help?

I think I got it going now. Although I think I did it at the expense of hardware acceleration with the iGPU. Also, I think FakeSMC was giving me the KP at boot. I now use VirtualSMC without issues. If nothing else I'd like to get a view into the contents of your EFI folder. The combination of kexts/Other + Library/Extensions + config.plist settings are somehow working in some cases and not in other cases. I can't seem to pinpoint exactly why. I am currently running AptioMemoryFix-64.efi in place of the usual OSXAptiofix3Drv-64 that @shatterhenner suggested or the OsxAptioFix2Drv-free2000.efi in conjunction with slide=0 which was an absolute must according to @CaseySJ OP here.

What's interesting is that you used his instructions to get your Presonus going, whereas I was unsuccessful with the VRS8. I know we're talking about two different products, but both seem to require memory within the first 256 of contiguous memory space, hence the discussion in this thread.

As it stands right now I have the following:
BIOS
VT-d > enabled
iGPU > disabled

Thunderbolt Memory
  • Reserved Memory → 737
  • Reserved PMemory → 1184
Clover Boot flags:
  • -v
  • keepsyms=1
  • darkwake=0
  • debug=0x100
  • -disablefixfirmware
  • slide=0

SMBIOS
iMac 19,1 (using 18,3 board ID - otherwise it won't boot due to "incompatibility")

I have it working without issues on my Z390 Designare with i9-9900k. In fact my UAD Apollo Twin MK2 seems to disconnect from time to time and a simple flip of the power switch on the UAD seems to bring it back to life, whereas this problem is non-existent on the VRS-8.
