Hackintosh Gigabyte GAMING X i5-9600K & RX 570

Verified working with Big Sur 11.1

Update: New Stable bios F10h from Gigabyte resolves the Apple Watch unlock issue and provides the CFG Unlock in the bios!!!!!! CFG Unlock is required for this EFI to work properly.

Configuration

- Motherboard: Gigabyte Gaming X
- BIOS: f10h
- CPU: i5-9600K
- RAM: 4x 8GB Crucial Ballistix Sport LT BLS2K8G4D30BESBK 3000 MHz, DDR4
- Storage: Samsung 970 EVO M.2 1TB
- dGPU: AMD Radeon RX 570
- WIFI/BT: FV-T919
- SMIBIOS 19,1
- OpenCore 0.6.6

Confirmed working

- Quick boot into MacOS and rock solid
- NVRAM if CFG Lock is disabled
- Fan and CPU temp information (see below)
- iMessage,Handoff and Approve & Unlock with Apple Watch
- Sleep and Wake from bluetooth mouse or keyboard
- iGPU Framebuffer for hardware acceleration (encoding/decoding/preview) including Apple TV DRM movies (shikivga=80) and SideCar
(note: Big Sur seems to break the support for Apple TV+, Amazon Prime Video still works fine in Chrome)

Known Issues

  • Multiple key press to wake from sleep with bluetooth (known issue with Gigabyte Gaming X or M boards)

Bios Setup:

- Make sure the IGP is set to Enabled for the Framebuffer to be recognised (Auto will not work)
- Disable CFG Lock
- Disable Serial Port
- Advanced Mode > Settings > Above 4G Decoding > Enabled
- Advanced Mode > Settings > USB Configuration > XHCI Hand-off > Enabled
- Advanced Mode > Boot > CSM Support > Disabled

USB Setup:

Some ports have been disabled to stay below the 15 port limit Ignore the Thunderbolt controller, this has been removed from this EFI.

Post Installation

  1. Setup Bios as per above
  2. Open your config.plist, go to PlatformInfo -> Generic and populate the Serial, Board Serial (MLB), SystemUUID and ROM (ethernet MAC address in Base64 more info). Make sure to edit the config.plist only with ProperTree.
  3. Go to System Preferences > Startup Disk and select your startup disk.
  4. Enable Trim.
  5. Done.

If you get stuck at OpenCore boot, try to clear nvram via OpenCore settings

Tips

  • Use Hackintool to validate correct implementation of Framebuffer and USB
  • Use Macinfo to generate your S/N
