Dear community,
I hope you will be able to help or guide me with my issue. Which I am trying to resolve already for a few days.

I used to have a hackintosh build of MacOS Sonoma based on Intel CPU. It was working fine.
Upon HW update to AMD (AMD Ryzen 7 7700 and msi x670e gaming plus wifi) and modifying my EFI folder for AMD I am currently stuck at [EB|LOG:EXITBS:START].

Please see attached EFI folder as well as OpenCore debug log file.

From what I see:
MMIO patched properly (proof is "skip 1" in boot log)
All AMD kernel patches loaded successfully.
I was a bit hesitant about IOPCIFamily.kext patch which AMD_Vanilla mentioned as mandatory for my CPU yet enabled by default. Because it was not clear to me what exactly that kext is. But it seems to me it is about com.apple.iokit.IOPCIFamily (CaseySJ | probeBusGated | Disable 10 bit tags | 12.0+) patch which is present, enabled and successfully loaded.
Hence I don't understand what else could be causing my issue.

Any clues from respectful community? :)

Have a look at this thread it is a guide for a similar system:


There are other threads for similar systems, the sites Search function is a handy tool.

The Success Stories forum is also a good source for those not knowing what they need for their system.
 
Thanks.
Yes, this is what I started from. Same chipset and similar CPU. So I believe I did everything what is mentioned there. What's applicable. Although there many things which are are different. Because of different hardware. Also it is written for older version of MacOS. Like for instance, it is talking about 3 patches for CPU, where you need to modify it based on the number of cores you have. All those applicable to older versions of MacOS (up to 13.0). Now there is forth patch exist, applicable for newer system (including Sonoma). So I used that as a base but unfortunately stuck anyway. There are should be something I'm missing. Something I don't see.
