AMD A10 7850K Graphics issue

[Nikos365]

Hi, I have changed the SMBios to iMacPro1,1, but the screen goes black. However, during installation and at the first boot, everything was excellent and friendly, but when I rebooted, the apple logo and the loading bar was loading, and the screen went black.

I have installed Monterey from the beginning 3x times just because had a sound problem(Stupid idea) I had to make changes in the EFI. The 3-time install is now, we speak, has no changes and is not bootable. I also fixed the ACPI thing...

I also tried to Change HDMI Cable to a different port, but..no luck at all
Here are my specs;

Asus strix RX480
Asrock A-68 FM2 DG3 Plus
16GB RAM

I have attached my EFI

Here are a few issues.

Make the following changes to your config.plist

- Remove SSDT-PMC in ACPI>Add section. It's not intended for your hardware.
- Remove ResetLogoStatus Quirk in ACPI>Quirks section.
- Kexts loading order is not correct. Important Kexts should load first.
- Remove the USB related kexts and consider mapping your USB ports.
- Remove AirPortBrcmFixup.kext from Kernel>Add section.
- Set KernelArch to Auto.
- Set Target to 3 in Misc>Debug section.
- Remove alcid=1 and -radcodec. It's not intended for your hardware.
- Remove the value for prev-lang:kbd.
- Drivers loading order is not correct. Important Drivers should load first.
- Remove VBoxHfs.efi and use OpenHfsPlus.efi.

Once you're done with the changes, save your config.plist. Restart the system and reset NVRAM twice. Attach the new PR files.

Make sure you're using a certified HDMI/DP Cable for display.

I made the changes. no boot at all, Unfortunately. The only way to boot the system is to add -amd_no_dgpu_accel, and the keyboard is not responding normally.
I've bought a new HDMI Cable

""" consider mapping your USB"""
The system does not boot normally. How the heck can I map USB ports?

It's a purely GPU thing, I believe. I also tried Open core legacy patcher for root patching, but not applicable

There are no significant changes in the attached configuration. Read post #3 again.

- Kexts loading order is not correct. Essential Kexts should load first.
- Remove the USB-related kexts and consider mapping your USB ports.
- Drivers loading order is not correct. Important Drivers should load first.
---------------------------------------------------------------------
How Can I Achieve the above order? I don't know how to place Kexts or drivers in order

I suppose propertree does the job for me CTRL + SHIFT +R

And How Do I map USB ports if I don't have access to OSX?


Some help, please

Anyways I did place them in order with CTRL + SHIFT + R

But I don't know how to map USB without Access...

Please Check EFI

The guide does not make use of ProperTree.

You should not worry about that now unless you fix rest of the areas.

NOTE: The .kext files must exist in EFI/OC/Kexts directory As the kext loading order is important for OpenCore, it is advised to load the kexts in sorted order. This means all the necessary kexts should be loaded first and dependencies kexts should load later to avoid issues. Your entries might differ as each system is different and will have different requirements. ---------------------------------------------------------------- It does not specify which kexts have to be in order. The same goes for drivers In my case, the are seven kexts for the most known work they do... Is Still do not understand to place them in order Any Help?

See the table. Notes are just additional info.

Typically, the order is Lilu, VSMC, WEG, AppleALC.

Ok, I found it. Drivers in order 1.OpenHfs.. 2. Open runtime. Check my EFI and pic for Kexts. The kexts are in order according to the table as mentioned
