Software Compatibility

• Big Sur (11.x)
• Catalina (10.15.x)
• Mojave (10.14.x)
• High Sierra (10.13.x)

There's no real support from AMD Vanilla for Monterey on 15th (FX Series) due to errors applying the patch and initializing the GPU on subsequent boot attempts.

Hardware Compatibility

This EFI is compatible with all FX processors with macOS-compatible peripherals.

Integrated	No
AMD	Yes 2 3

For AMD Navi 10 Series GPUs (RX 5500, RX 5600, RX 5700) agdpmod=pikera is added to boot-args to fix the black screen issue.

Use EFI_Dual to blacklist any secondary GPU that might interfere with booting (change the disable-gpu key value, and use SSDTTime to address your GPU properly.

Installation

Bootable USB

1. Follow this guide to create your bootable USB.

2. Clone this repository and copy the "EFI" directory to the same directory of your BaseSystem.dmg on your bootable USB.

SMBIOS

3. Use this tool to generate your unique SMBIOS info.

• SMBIOS has to be unique, you cannot use one present in this repository.

• Run the tool and select Generate SMBIOS.

• Select the appropriate model for your hardware using the table below.

• Go to Apple Coverage and paste generated Serial. You need "Invalid Serial" or "Purchase Date not Validated" message. If you get something another you have to generate SMBIOS data and check it again.

• Open config.plist and search for PlatformInfo -> Generic and replace these values:

  • SystemProductName - Model
  • MLB - Board Serial
  • SystemSerialNumber - Serial
  • SystemUUID - SmUUID

• ROM entry should be set to your network card's MAC address, without separators (e. g. :, -).

GPU Series	Model
AMD Navi Series	iMacPro1,1 1
AMD Vega Series	iMacPro1,1 1
AMD Polaris Series	iMacPro1,1 1
AMD Radeon R5/R7/R9	MacPro6,1
AMD HD 8000 Series	MacPro6,1
AMD HD 7000 Series	MacPro6,1
Nvidia Kepler Series	MacPro7,1 2

¹ For Catalina and newer you can also use MacPro7,1 if you have some issues (e. g. unfixable DRMs).

² For Catalina and older use iMac14,2.

Configuration

4. You should update your BIOS to the latest version and configure it appropriately. See BIOS Settings for details.
5. Map your USB ports with USBToolBox. Guide about it is available here. You have to do it from Windows.
6. That's it! Now you can boot macOS installer.

Post-Installation

7. Copy your EFI directory onto your main drive EFI partition, you'll be able to boot the system without your bootable USB.
8. When everything work you can disable verbose mode - then you will see Apple's logo instead of logs while booting. To do it you have to remove -v debug=0x100 keepsyms=1 from boot-args in your configuration file.

Bootstrap

In general, enabling Bootstrap is not required, but it will protect your OpenCore from being overriden.
Remember to do not enable Bootstrap on pendrive - do it only after copying OpenCore to your disk's EFI.

9. Go to Misc -> Boot -> LauncherOption in your configuration file and set it to Full.
10. Reboot your computer.
11. Reboot PC again and go to your BIOS settings. In boot options you will see new boot entry named OpenCore. Set BIOS to boot from it, instead of your drive.
12. It's done!

Virtualization

This setup can be virtualized from Linux with KVM support using my osx-kvm build.

Isolating the CPU is strongly suggested, to improve latency, especially for any audio I/O Performance optimization.
