Hi,

I'm working with Claude to try to build this:

CPU: AMD Ryzen 7 9800X3D
Motherboard: Gigabyte X870E AORUS Elite WiFi7 (ATX, AM5)
GPU (temporary): XFX RX 570 4GB — in primary PCIe x16 slot for build phase
GPU1 (gaming): ZOTAC RTX 5090 SOLID 32GB — removed during build phase, needs SSDT to hide from macOS laterGPU (macOS):
GPU2: PowerColor Red Devil RX 6900 XT 16GB (Device ID 0x73BF) — will go in AOOSTAR AG02 eGPU dock eventually
RAM: 2 x 48GB DDR5 Corsair Vengeance — not yet purchased
Case: be quiet! Dark Base Pro 900 v1
PSU: Corsair HXi 1200W ATX 3.0

I'm not very far in to be honest. It's hanging at the place shown in the attached photo when booting from the USB. I haven't yet reached the start point of the install. I've attached the EFI here.

I've tried:
  • SetupVirtualMap → false (AM5 requirement per mikigal README)
  • SecureBootModel → Disabled
  • DmgLoading → Any
  • AM5 PCI bus enumeration fix → enabled
  • DevirtualiseMmio → true then reverted to false
  • EnableWriteUnprotector → true
  • ProtectUefiServices → true
  • DisableIoMapper → true
  • csr-active-config → 03000000
  • boot-args additions: agdpmod=pikera, amfi_get_out_of_my_way=1, revpatch=sbvmm, npci=0x2000
  • Updated OpenCore from 1.0.4 to 1.0.7
  • Bypassed KVM, plugged keyboard directly
  • Tried USB 2.0 port
The installer was downloaded as version 19.8.42

Any ideas where I'm going wrong?

Thanks in advance!

You might want to have a look in the Success Stories forum, as there are some other AMD 800 Series systems that have been mentioned and are running macOS.


You may be able to see what is different in your setup compared to the other OC EFI’s.
