I try to install OSX on my AMD Epyc System

[theshadowpeople]

Hello
I try to install OSX on my AMD Epyc System ( Supermicro H11SSL-i with AMD Epyc 7551 and AMD Radeon RX490 )

It boots from the USB stick and loads a little and then restarts.

Can someone help me to install OSX ?

Try this revised config.plist see if it allows you to boot. I have made changes in line with what the Higher end AMD boards require.

Post a screen image showing where it stops, if the system kernel panics while using this config.

Hey thanks for your help but unfortunately it's exactly the same error.
I found three more threads here in the forum that have the same error. One of them said that this error is not in version 11.6.1 but with version 12. Unfortunately there was no solution to the problem here either.

By that did they mean installing macOS Big Sur would work and that they couldn't install macOS Monterey?

Have you tried booting with a macOS Big Sur installer?

Can you post a copy of your EFI folder so I can get a better understanding of what you are using.

Can you post a photo of the verbose text when it kernel panics, as that might tell us what needs fixing.

Did you add AppleMCEReporterDisabler.kext to your config.plist? This is needed for booting Monterey 12.3. As far as I am aware Big Sur 11.6 also requires it.

If anything I'd also check AdviseWindows and ProvideCPUInfo when booting Monterey/Big Sur 11/6. Also try adding -no_compat_check to the end of your NVRAM boot-arg - it can help with bypassing SMBIOS checks.

Just note that Epyc is very different from Threadripper. It is an SoC and does not use a chipset, all I/O is provided by the CPU.

I forgot to put the entry on the ProvideCurrentCpuInfo on true. Now he boots but it doesn't want to run.

Edit
Most restarts come after the [PCI config (Picture 2)

There are a few issues that can cause the 'PCI Configuration Begins' kernel panic, as listed in the OC Troubleshooting guide linked below.

# PCI Configuration Begins troubleshooting

The PCI allocation issue section is AMD related.

Have you set Above 4G Decoding as Enabled in your bios? If not you need to add 'npci=0x2000' boot argument to your config.plist.

 

[theshadowpeople]

Above 4G Decoding was already on. I also made a BIOS update and tried the setting NPCI = 0x2000 and "Above 4G Decoding off". Unfortunately no success.

 

[Edhawk]

Have you tried any of the other fixes offered by the troubleshooting guide?

 

[theshadowpeople]

As far as I can see that, yes.
I attached my EFI folder and a debug file. Maybe you will see the mistake
