Change AAPL,ig-platform-id to 0300C89B (generic VESA driver) and cross your fingers. Expect purple tint or no signal. Boot Arguments (NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args) Add these to your existing arguments:
| Key | Type | Value | Explanation | | :--- | :--- | :--- | :--- | | AAPL,ig-platform-id | Data | 00000000 | Disables display output (headless mode). | | device-id | Data | A67E0000 | Spoofs Intel UHD 770 as UHD 7xx (Comet Lake). | | enable-hdmi20 | Data | 01000000 | Optional: Enables HDMI 2.0 if needed. | | framebuffer-patch-enable | Data | 01000000 | Enables custom framebuffer. | | framebuffer-fbmem | Data | 00000003 | 48MB framebuffer memory. | uhd 770 hackintosh
Find your iGPU PCI path (usually PciRoot(0x0)/Pci(0x2,0x0) ). Add these properties: | | device-id | Data | A67E0000 |
If you are a tinkerer who enjoys the journey more than the destination, go ahead—build that Z690 + i7-12700K Hackintosh and wrestle with framebuffers. But if you need to get work done, either disable the UHD 770 entirely in BIOS and use an AMD dGPU, or build a native Mac. | | framebuffer-fbmem | Data | 00000003 |
The UHD 770 is a powerful iGPU on paper, found in chips like the i5-12600K, i7-12700K, and i9-13900K. It supports hardware decoding for HEVC and can drive 8K displays. But will it work in macOS Ventura or Sonoma?
