Big Sur on AMD EPYC / Supermicro H11SSL-i

[benjoe]

Hi everyone!

I have tried to install macOS BigSur on my AMD EPYC machine - with no success so far. I have tried Sonoma and Big Sur so far, but I was unable to reach the installation screen. I have created my installer based on the OpenCore Dortania Guide but my system always gets stuck after "ACPI tables successfully loaded"

Hardware:
Motherboard: SuperMicro H11SSL-i
CPU: AMD EPYC 7302P 16 Cores / 32 Threads
GPU: AMD RX580

You will find my current EFI-Setup attached to this post (+ my latest opencore log). I hope somebody can give me some advice on what the look for...AMD EPYC is driving me nuts, I have built some Intel Hackintoshes in the past so I have some experience with OpenCore and how to setup the installer.

I have to be honest and tell you I have no experience with this flavor Motherboard or Processor, the processor is based on Zen 2 so I'm thinking it should be similar to the setup for a Ryzen machine but again I don't know that. You had some booter and kernel quirks enabled that are for TRX40 boards, not sure if that would apply so I turned them off, enabled DummyPowerManagement in Kernel/ Emulation and updated your Kernel Patches. You only had the first three of four needed typically to define the processor cores.
It may work, may be a complete and total waste of your time. Maybe @Edhawk has some insight....

Never used an EPYC CPU (AMD Server CPU) or A SuperMicro MB for a Hack so this would be new territory for me. I believe both will require additional SSDTs and possibly some additional Bios changes to run macOS.

Thank you guys, I will try to rebuild my whole EFI folder again and check out some bios settings again, maybe I need to disable some other stuff as well.

@leesurone I have tried your modified EFI folder, but I still get stuck at the same step as before (ACPI tables successfully loaded).

If available in the bios enable Above 4G Decoding, if not then you probably need the ncpi=0x2000 ncpi=0x3000 boot argument. Without either you typically get that early boot failure.

Above 4G was already enabled when I did my initial tests. IOMMU was enabled before, but I did disable it afterwards but this didn't solve it unfortunately.

BIOS Settings that I have enabled / disabled:

• All Serial Port / Parallel port related stuff -> disabled
• Above 4G Decoding -> enabled
• IOMMU -> disabled
• SecureBoot -> disabled
• CSM -> disabled
• SVM -> enabled
• XHCI / EHCI -> enabled
• FastBoot -> disabled
• CFG Lock on SuperMicro Motherboards cant be disabled without BIOS Modifications, but there is an appropriate OpenCore setting to tackle this issue.
• SATA-Mode: AHCI

As Edhawk says it may require additional SSDTs to boot. Its a shot in the dark but you could try adding SSDT-CPUR.aml that AM5, 550 and 520 series boards need to boot.

Can you load up a debug build of OpenCore and enable SysReport in your config and upload the folder it creates in your EFI.

@leesurone @Shaneee I will try all of your suggestions in the evening Thanks in advance.
