Hello,i have FX8300,RX580 4GB,Asrock 760 GM HDV.When i am building a efi using latest opencore version i am getting this error(see images)
It would seem simple just fix this issue using opencore troubleshooting guide.But when i am using older amd vanilla,nothing changing.
BUT, i found older completed efi's (oc 0.54 - 0.7)
I don't get this error.But getting another error and black screen after that (screen displays just nothing,but don't show that there isn't a signal) (IOConsoleUsers: gIOScreenLock.../gIOLockState) Which often appears because CSM is not turned off,but i don't have this setting in my bios and using gpu-z in windows i checked,my motherboard don't using csm,because it don't have it.

You might want to have a look at the EFI for my FX 8350 system linked below and the OC 0.8.3 EFI in the second link.


Post #28 contains OC 0.8.3 EFI

I am currently using OC 0.9.0 on that FX system running macOS Catalina. Copy of the latest EFI is attached below.
  1. You need to add the MLB, ROM, Serial Number and SystemUUID to the config.plist.
  2. You won't need to edit the AMD Kernel Patches, they are the latest, and your system and mine both have an 8-core CPU.
