: The official Dortania Anti-Buyer's Guide explicitly lists UHD 770 as unsupported.
Sometimes, enabling too many display connectors on an iGPU that is only used for computing (if you have a dedicated AMD card) causes heat.
If you are building a Hackintosh with a 12th/13th/14th Gen Intel CPU, you use a compatible discrete GPU (dGPU) to get a functional system: uhd 770 hackintosh hot
or 6000 series) instead of relying solely on the UHD 770 iGPU.
Additionally, ensure you allocate sufficient DVMT Pre-Allocated memory (at least 64MB) in BIOS settings to prevent graphics-related issues. These settings are critical for a smooth and stable experience. : The official Dortania Anti-Buyer's Guide explicitly lists
If you have a discrete AMD GPU for displays, set UHD 770 as (compute only):
Navigating the Reality of Intel UHD 770 Hackintosh Compatibility Because the UHD 770 is masquerading as an
This is where the "hot" keyword becomes literal. Because the UHD 770 is masquerading as an older UHD 630, the driver matching is imperfect.
An essential tool for assessing framebuffer and graphics configuration. 2. Fixing UHD 770 Heat Issues in OpenCore The primary solution involves optimizing your config.plist . A. Correct Device Properties (Proper iGPU Identification)
Before applying fixes, you need to know how hot your system is running.
Benchmarks show the UHD 770 can be anywhere from 70% to over 85% faster in certain tests. Its GPU cores are newer, and its boost clock is about 35-55% higher, reaching up to 1.55 GHz. The community's frustration is palpable—they have powerful hardware that macOS cannot use.
