I have been playing around with my old AMD FX 8350 system (again) and decided to see if I could get it running macOS Big Sur.
I used OpenCore 0.7.6 and followed the Dortania AMD Bulldozer guide when creating the EFI folder.
I created my macOS Big Sur USB installer using the following CreateInstallMedia Terminal command:
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled
Installation was slow, with many pauses and some initial Kernel Panics during the various installation stages. However, the end result was Big Sur 11.6.1 was installed on the old AMD system.
I have attached below a copy of the EFI folder I used, obviously with the Serial Number etc redacted from the config.plist. So you need to add your own if you choose to use this EFI folder. I used the MacPro6,1 SMBIOS, just because, not for any specific reason. You could just as easily select an iMacPro1,1 or MacPro7,1 if you wish.
The screenshot below show the expanded contents for the OC folder:

Here is a screenshot showing the About this Mac window, after updating the system to Big Sur 11.6.2, using the Apple Software Updater method.

I will provide another post below, with a number of Bios screenshots, so you can see how I set up my bios.
A further post will contain some more screenshots, showing the components, setup and other information from the FX 8350 system.
