Post a copy of your EFI folder, so we can see what you are using.

Remember to delete/redact your serial number from the config.plist before you post a copy here

Try this OpenCore 0.7.6 EFI with your AMD FX system.

I have populated the SMBIOS data, using a MacPro6,1 SMBIOS.

This is inline with my working FX8350 system, which I have running Big Sur and Monterey. https://forum.amd-osx.com/index.php...0-oc-0-7-6-big-sur-11-6-2-monterey-12-1.2400/

The later not great as I am using an Nvidia GTX 690 for Graphics. Your RX570 should work much better.

All you need to do is rename the EFI-AMD-0.7.6 to EFI and it should work.

Which Error message?

Post/attach a photo of the error message, so we can see what you are seeing.

It doesn't shows it now so I can't take a photo .I believe that the problem is the login window in Monterey because in the past I had to disable it so I can run Monterey
