Installation

Follow the OpenCore Vanilla Desktop Guide — specifically the Coffee Lake section. This config targets a desktop dGPU-only setup (no iGPU output), so:

1. Download the latest release EFI from the Releases page.
2. Mount your EFI partition and replace the existing EFI folder.
3. Apply the BIOS settings above.
4. Boot from the USB installer and install macOS normally.

⚠️ Generate your own SMBIOS serials before first boot. Never share MLB / ROM / Serial values publicly. The checked-in OC/Config.plist intentionally leaves these values blank.

This repository is a personal compatibility reference for one hardware build. It is not a universal EFI, and it does not include Apple software or any private serial identifiers.
