- 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.

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