770 Hackintosh — Uhd

It is critical to note that the Intel UHD 770 integrated GPU (iGPU) found in 12th, 13th, and 14th Gen Intel CPUs is not natively supported by macOS and currently has no known method for full hardware acceleration . While you can run macOS on Alder Lake or Raptor Lake systems by spoofing the CPU, the UHD 770 will lack the drivers (QE/CI) needed for a smooth interface, resulting in extreme lag and graphical glitches. 1. Recommended Hardware Alternative To achieve a functional Hackintosh on a system with a UHD 770, you must use a compatible dedicated GPU (dGPU) .

Basic Setup Strategy (CPU Spoofing) Since macOS does not recognize 12th-14th Gen Intel CPUs, you must "trick" the system into thinking it is a 10th Gen Comet Lake CPU. SMBIOS : Use iMacPro1,1 or MacPro7,1 for desktops with a dedicated AMD GPU. CPU Spoofing : In your config.plist under Kernel -> Emulate , set: Cpuid1Data : 55060A00 00000000 00000000 00000000 Cpuid1Mask : FFFFFFFF 00000000 00000000 00000000 . Essential Kexts : Ensure you have Lilu and WhateverGreen for general stability and graphics management.

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 uhd 770 hackintosh

You must disable the E-cores in BIOS or via CPU topology kexts for stable macOS. Many users run with E-cores disabled entirely.

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. It is critical to note that the Intel

3. Boot Arguments Add these to NVRAM → Add → 7C436110-AB2A-4BBB-A880-FE41995C9F82 → boot-args : igfxonln=1 igfxrpsc=1 -igfxblr -igfxsklaskbl

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)
