To achieve a functional Hackintosh with Intel UHD Graphics 770 (Alder Lake / Raptor Lake), you must understand a critical limitation: UHD 770 is not officially supported in macOS because no real Mac has ever used Alder Lake or Raptor Lake desktop CPUs. However, you can get full acceleration (metal support, UI smoothness, video decode) by spoofing the iGPU as a supported model. Here’s the proper configuration.
1. Prerequisites – CPU Compatibility UHD 770 is found on:
Alder Lake (12th gen) – e.g., i5-12600K, i7-12700K, i9-12900K Raptor Lake (13th/14th gen) – e.g., i5-13600K, i7-13700K, i9-13900K
You must disable the E-cores in BIOS or via CPU topology kexts for stable macOS. Many users run with E-cores disabled entirely. uhd 770 hackintosh
2. Required Device Properties (config.plist) Add these properties to PciRoot(0x0)/Pci(0x2,0x0) : | Key | Type | Value | |------|------|--------| | AAPL,ig-platform-id | Data | 07009B3E (for desktop) or 00009B3E (alternative) | | device-id | Data | 9B3E0000 (spoofs as UHD 630) | | enable-backlight-registers-fix | Data | 01000000 (if laptop, but desktop often skips) | | framebuffer-patch-enable | Data | 01000000 | | framebuffer-stolenmem | Data | 00003001 | | framebuffer-fbmem | Data | 00009000 | Explanation:
device-id = 9B3E0000 → This tells macOS to treat UHD 770 as a UHD 630 (Coffeelake), which has native support up to macOS Ventura/Sonoma. AAPL,ig-platform-id = 07009B3E → Desktop headless (if using discrete GPU) or 00009B3E for single iGPU output.
3. Boot Arguments Add these to NVRAM → Add → 7C436110-AB2A-4BBB-A880-FE41995C9F82 → boot-args : igfxonln=1 igfxrpsc=1 -igfxblr -igfxsklaskbl To achieve a functional Hackintosh with Intel UHD
igfxonln=1 → Forces online status for connectors (fixes black screen) igfxrpsc=1 → Enables proper power gating
4. BIOS Settings (Critical) | Setting | Value | |---------|-------| | CSM | Disabled | | Above 4G Decoding | Enabled | | Resizable BAR | Disabled (causes issues on Hackintosh) | | DVMT Pre-Allocated | 64MB or higher | | Primary Graphics Adapter | IGFX (if no dGPU) or PEG (if dGPU) | | VT-d | Disabled (or use dart=0 ) | | CFG Lock | Disabled | For E-cores (if you keep them enabled): Use CpuTopologyRebuild.kext and -ctrsmt boot argument, but stability varies.
5. Recommended Kexts
Lilu.kext (latest) WhateverGreen.kext (latest – critical for iGPU patching) VirtualSMC.kext (not strictly required for graphics, but standard)
6. macOS Version Support | macOS | UHD 770 Support | |-------|----------------| | Monterey (12) | Yes (spoofed) | | Ventura (13) | Yes (spoofed) | | Sonoma (14) | Yes (spoofed) | | Sequoia (15) | Unstable / not recommended | Use Ventura 13.4+ or Sonoma 14.2+ for best stability.
