Random reboots while loading the system

[lopess]

I can't find what the correct SSDT order should be. Could you tell me where I can find this information?

GPU Details

As expected, its the XTXH variant. Spoofing is required. Spoof the device ID to 73BF

See the guide. Its mentioned there.

The spoof method didn't work for me. I followed this guide:

https://elitemacx86.com/threads/how-to-spoof-graphics-on-macos-intel-amd-nvidia.1008/

My ACPI Path is: _SB_.PC00.PEG1.PEGP

But this is not the most important problem for me, because the graphics card works correctly with NootRX.kext.

Unfortunately none of the settings changes you suggested helped with my problem. Nothing has changed. The system still loads occasionally, from time to time.

But I'll return to my question – is there anything in the logs?

You need to adjust a little. Scope (_SB.PC00.PEG1) and then define

Scope (PEGP)
{
Name (_STA, Zero) // _STA: Status
}

Before the GFX0. If the SSDT method is difficult for you, just use DeviceProperties method and that should work fine and no, you should not use NootRx when you can use the native drivers.

Original patch was:

03:00.0 1002:73af /PC00@0/PEG1@1/PEGP@0/pci-bridge@0/GFX0@0 = PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

I used SSDT-BRG0.aml to change pci-bridge@0 to BRG0@0
Now is:

03:00.0 1002:73af /PC00@0/PEG1@1/PEGP@0/BRG0@0/GFX0@0 = PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

Now SSDT-GPU-SPOOF.aml should work as expected, but don't work.

Finally I used SSDT-BRG0.aml and spoof to BF730000 in device properties. Now WHG works, but it doesn't solve my system startup problem. I don't know why I also lost the CPU type and serial number information provided in "About Mac." Could any of the changes you recommended have caused this?

Not unless if you changed the SMBIOS. If you didn't do that, then it was due to CustomSMBIOSGuid

- ACPI files are not loading in sorted order.
- Renames are depreciated and handled by Lilu, WEG and AppleALC itself.
- FadtEnableReset and ResetLogoStatus shouldn't be needed for your hardware.
- EnableWriteUnprotector shouldn't be needed for your hardware.
- ResizeAppleGpuBars must be set to -1.
- Remove all the Device properties
- Kexts are not loading in sorted order. Important kexts should load first.
- CustomSMBIOSGuid shouldn't be needed for your hardware.
- NootRX shouldn't be used as 6900XT works OOTB.
- SetApfsTrimTimeout must be set to default.
- HibernateSkipsPicker and PollAppleHotkeys shouldn't be needed as well.
- Do you really need the Ntfs and Ext drivers?

But the system's behavior hasn't changed. The problem persists. The system does not start every time properly. From the log files, it seems to me that these are some NVRAM issues.

Any other tips?
