Uhd 770 Hackintosh

Critical warning before you start:
UHD 770 is NOT fully supported in any macOS version.
Apple never used Alder Lake/Raptor Lake CPUs. The iGPU has no native driver and no amount of patching enables full acceleration (Metal/QE/CI).

Kernel → Add

• Required Kexts: Lilu.kext, WhateverGreen.kext, VirtualSMC.kext.
• CPU Friend: CpuTopologyRebuild.kext (fixes E-core/P-core threading).

NVRAM → Add → 7C436110-AB2A-4BBB-A880-FE41995C9F82

• boot-args: -igfxvesa igfxframe=00009B3E -wegtree -cdfon agdpmod=pikera (use -igfxvesa for basic VESA mode if no acceleration).

Boot Arguments (NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args)

Add these to your existing arguments:

-igfxvesa -igfxmpc igfxonln=1 -disablegfxfirmware

• -igfxvesa: Forces VESA mode (no acceleration but ensures boot).
• -igfxmpc: Disables power management checks.
• igfxonln=1: Forces online status for displays.
• -disablegfxfirmware: Skips Intel GuC/HuC firmware loading (prevents kernel panics).

2. DeviceProperties (config.plist)

Add to PciRoot(0x0)/Pci(0x2,0x0):

<key>device-id</key>
<data>kl4AAA==</data>   <!-- 0x3E9B -> spoof as UHD 630 -->
<key>AAPL,ig-platform-id</key>
<data>BwCbPg==</data>   <!-- 0x3E9B0007 desktop UHD 630 -->
<key>model</key>
<string>Intel UHD Graphics 770</string>

Why? Spoofing as UHD 630 (Coffee Lake) lets macOS drive the framebuffer, but still no Metal. uhd 770 hackintosh

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 | Critical warning before you start: UHD 770 is

For E-cores (if you keep them enabled): Use CpuTopologyRebuild.kext and -ctrsmt boot argument, but stability varies. Kernel → Add
