@schlosrat,
Although you have a Z390 AORUS Pro and not the Designare, you can still try using the OpenCore 0.8.3 EFI folder from
this post.
Do you have any Hackintosh kexts installed in Catalina's
/Library/Extensions
folder? Those will interfere with OpenCore.
Thanks
@CaseySJ! That's a great looking guide!
I assume there are not Hackintosh kexts in the /L/E foler since I did a clean install wiping the drive with Disk Utility prior to installing. I think all that would be in /L/E is whatever the Monterey installer put there, and when I ran that it was after booting from an OC USB, so probably no Hackintosh kexts! Could I be wrong about this?
Can I use the latest version of OCC (2.63.0.0) with OC 0.8.5 and your guide? I assume if I copy EFI folder I'll be getting OC 0.8.3 with your OpenCore.efi file. This might be two questions. Can I use OCC 2.63.0, and can I replace the 0.8.3 OC efi with the 0.8.5 efi?
Using OCC 2.63.0, the only options I've got are for OC 0.8.5 Release and 0.8.6 Development, so I went with 0.8.5 Release and replaced the drivers with the corresponding 0.8.5 versions. Ditto for tools that shipped with 0.8.5.
I copied config-AMD-GPU.plist to config.plist since I've got an AMD GPU.
I populated screens per your guide, choosing Default for SecureBootModel, and 0 for SetApfsTrimTimeout since I've got a Samsung NVMe SSD. For my system product name I went with an iMac19,1 since that corresponds to my i9 processor. This gave me a ProcessorType of 4105.
With all that in there, I was suprised how quickly it booted and got to the OpenCanopy GUI. I selected my WSD500, and then it hung at an apple logo with no progress bar.
I'm going to try next with the 0.8.3 drivers and files in your EFI, SecureBootModel = Disabled, but still using OCC 2.63.0 and the iMac19,1 setting.
Can I use an iMacPro1,1 setting like you have when my CPU is not a Xeon?
