Notes
This EFI is designed specifically for:

- Intel Core i7-9700F
- Sapphire Pulse Radeon RX 580
Since the i7-9700F does not include Intel UHD Graphics, this EFI requires a supported dedicated AMD graphics card. The RX 580 provides native macOS support and does not require additional graphics patches.
