    @CaseySJ Just spoofed successfully device-id of Radeon Pro VII to Radeon VII on cMP5,1: DefinitionBlock ("", "SSDT", 2, "DRTNIA", "AMDGPU", 0x00001000) { External (_SB_.PCI0.IOU0.PXS1, DeviceObj) External (DTGP, MethodObj) // 5 Arguments Scope (\_SB.PCI0.IOU0.PXS1) {...

    Swapped a Radeon VII for 6900XT Red Devil (xtx) but won't work (Big Sur)

    The app’s authorization has been revoked (High Sierra NVIDIA graphics certificates expired)

    Nvidia certificates were long time expired (2015), but that is not the reason for them not to work. They were recently revoked due to Lapsus$'s security breach and subsequently malware found signed by the stolen certificates. This was done to invalidate them. Unfortunately as you can see that...

    Oh yeah. it is not mine. I am just trying to help, but I will let him know. I just like challenges and impossible missions. Still would be nice to know what is dying. Anyway to log something related to the shutdown? I don't see any panic logs whatsoever except the message "your computer was...

    I think I found the problem: https://github.com/acidanthera/bugtracker/issues/1743 https://github.com/carlox97/Getting-Started-With-ACPI/blob/2aa3f875db6f8104def3f8e5b7886671d294505f/extra-files/decompiled/SSDT-GPU-SPOOF.dsl

    Yes, but again the injection works fine if no device-id is spoofed. I wish I could capture a panic log that I can share with Acidanthera team to see why OC is crashing. I will tests it, but at this point it is probably better to collect somehow a detailed debug/panic log.

    Not Yet. Not sure how to do it correctly.

    @CaseySJ I just realized I was booting all the time deleting the original SSDT-5 table. Attached is the Ioregistry with the SSDT-5 loaded and device-id missing from the SSDT.

    I can inject anything but the device-id. As soon as device-id is injected OC crashes. What gives?

    I have a little progress: I removed the device-id and now have this: Still cannot load the kext though. DefinitionBlock ("", "SSDT", 2, "Apple", "AMD6950", 0x00000000) { External (_SB_.PC03, DeviceObj) External (_SB_.PC03.BR3A, DeviceObj) External (_SB_.PC03.BR3A.US00.DS00...

    Thanks for that. Will test it on Friday maybe (when I get a remote access to the machine). Strange, but this is how the spoofing inside the DSDT worked before: /* * Intel ACPI Component Architecture * AML/ASL+ Disassembler version 20200925 (64-bit version) * Copyright (c) 2000 - 2020 Intel...

    Also there is a modified DSDT used to disable NVIDIA GPU on the MP71, which works:

    I sold my cMP5,1 some time ago, but I was using SSDT to inject properties there no problem at all. Apparently though MP7,1 has issues. What gives?
