[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[CaseySJ]

Thank you so much, @CaseySJ.

• The vendor name and UUID now show up.
• The speed is still showing as 20GB/s

Things I've tried:

• Using Device Properties in config.plist to add the GPUs using Hackintool and IOReg (and this forum) for help.
  • This has meant I can cold boot with BOTH eGPUs connected and I see the 5700XT and can also eject it but the 3rd Radeon VII shows up as "Display" so that tells me the drivers aren't loading properly for that card.

So my plan is to add the device using Device Properties to see if that helps things.

Is there anything else you would suggest? In particular to get the speeds at 40GB/s?

For the time being, I wouldn't worry about 40Gbps versus 20Gbps. Instead, try adding Device Properties as you stated. Let's see if all four GPUs can initialize regardless of link speed or link width.

• After making the changes, please post screenshot of System Information --> Thunderbolt and System Information --> PCI.

@CaseySJ I changed a lot of settings per the list and it works...

Glad to hear it. Good job.

@CaseySJ I added the device properties for just the Radeon VII as the 5700XT was showing up correctly. Should I have added both? (See edit 2).

Here are the requested images. As you can see the Radeon VII isn't showing up correctly and the naming of the internal GPUs is different to what I set up in Device Properties i.e. they now both say Slot-1... not sure if that is a big deal or not?

Edit 1: Added an image of Graphics/Displays for completeness.
Edit 2: I tried adding the 5700 XT and the results weren't beneficial.

@CaseySJ I don't know whether this is relevant but during boot I get this pause before the boot continues:

The system boots when the 5700 XT is in the top TB3 port but if the Radeon VII is there we end up with the this:

Is this something that could be added in device properties or with an SSDT?

** OpenCore 0.6.5 EFI for Designare Z390 **
Supports Mojave, Catalina, and Big Sur
Please do not quote this post in its entirely. Use a link instead.

Requires OpenCore Configurator 2.22.0.0 or Newer

​

The formal release of OpenCore 0.6.5 has arrived, along with an update of WhateverGreen, AppleALC, NVMeFix, and IntelMausi.

This EFI contains the following changes:

Bootloader / Kexts:
All of the items listed below are official builds.

• OpenCore 0.6.5
• WhateverGreen 1.4.6
• AppleALC 1.5.6
• NVMeFix 1.0.5
• IntelMausi 1.0.5

config.plist Changes:

• Booter --> EnableWriteUnprotector --> False
• Misc --> Security --> SecureBootModel --> Disabled (change to Default for OpenIntelWireless)
• Misc --> Security --> BlackListAppleUpdate --> Enabled

How to Use:

1. Find a USB flash disk with an EFI partition, or format the USB flash disk in Disk Utility with Scheme = GUID Partition Map and Format = MacOS Extended (Journaled).
2. Mount EFI partition of the USB flash disk.
3. Download the attached ZIP into the top level of the EFI partition of the USB flash disk. When the file is unzipped, there will be a folder called OC-065-DESIGNARE-Z390.
4. Rename this folder to EFI, otherwise the system will not boot.
5. Use HackinDROM to transfer PlatformInfo from existing OpenCore config.plist to new version. Please follow the guide by clicking here and referring to the screenshot below.

​

After the modified config.plist has been copied to the EFI/OC folder of the USB flash disk, proceed as follows:

1. Reboot and press F12 at the BIOS Splash Screen. When the BIOS Boot Menu (not OpenCore Picker) appears, select the USB flash disk.
2. Warning: It is necessary to reset NVRAM one time prior to booting macOS. This can be done by pressing spacebar at the OpenCore Picker and choosing Reset NVRAM. On multi-boot systems, select the default startup disk in System Preferences --> Startup Disk.
3. At the OpenCore 0.6.5 Picker menu, select and boot the internal macOS disk.
4. If everything works correctly, copy the new OpenCore EFI folder from the USB flash disk to the EFI partition of the main macOS SSD.

CAUTION:

• If you are using a custom Thunderbolt SSDT or any other custom SSDTs or Kexts, please update your config.plist accordingly.

Update to OC 0.6.5 went smoothly. Thanks for the heads up!

The 'DeduplicateBootOrder' key can be removed from the included AMD config in the zip on this version. It looks like it's still in there.

Update to 0.6.5 fine.

Get message on bios start-up 'OCS: No schema for DeduplicateBootOrder at 0 index, context <Quirks>!'

What's that about?

Thanks for pointing this out:

• This affected only config-AMD-GPU.plist and has been resolved in the updated EFI posted a moment ago.
• In addition to "DeduplicateBootOrder", it was also necessary to add "SetupDelay" in the Audio section of UEFI. This has also been done.

To fix this problem without having to re-download the EFI or transfer PlatformInfo credentials, simply do this:

• Download OpenCore Configurator (OCC) 2.22.0.0 or newer
• Open OCC --> Preferences and set the Configuration as shown:
  
• OCC will restart.
• Then open config.plist in OCC and save the file.
• Optional: Verify the changes by opening config.plist in a Plist or Text editor such as PlistPro, ProperTree, or BBEdit and check if "DeduplicateBootOrder" is gone and if "SetupDelay" is present.

I'm afraid the disclaimers I mentioned earlier now apply! Namely, Thunderbolt Bus has been activated properly, but now the rest is up to macOS, your board's firmware, and the Thunderbolt devices being connected.

If all four GPUs worked in Catalina (pre-flash) but don't work in Big Sur, that points to issues/changes in Big Sur itself. If you can duplicate the problem on a real Mac Pro, you would be within your rights to report it to Apple.

Another option is to check the eGPU.io website, which is dedicated to eGPU-related technical issues.

After installing BIOS F9i please confirm whether the following were done:

• Configured BIOS parameters according to Post 1, starting with F7 (Load Optimized Defaults)
• Set CFG-Lock to Disabled in the Boot section

I was struggling switching to OpenCore when I saw this post.
I was missing CFG-Lock Disabled.

@CaseySJ Thanks a lot for your hard work and the precision of your guides.

I also went from OC 0.6.4 to OC 0.6.5 flawlessly.
Now I can add myself to the Radeon RX 6xxx driver wait list
