By using specific parameters inside your boot configuration, you can pass fake device IDs to simulate an older engine: Target Device Location : PciRoot(0x0)/Pci(0x2,0x0)
Platform ID: 0x0300C89B Device ID: 0x9B681086
Which (e.g., Ventura, Sonoma, Sequoia) are you targeting?
Native-like framebuffer injection
To get your UHD 770 working "hot" (with full Metal 3 support and acceleration), you need to implement specific DeviceProperties in your OpenCore config.plist :
No. The , and there is no way to achieve native hardware acceleration (QE/CI) with it.
Now we move from "it boots" to "it flies." Here is how to unlock the heat. uhd 770 hackintosh hot

Tackling the Heat: Managing UHD 770 Hot Temperatures in a Hackintosh Build
The UHD 770 is integrated into the CPU die. 12th, 13th, and 14th Gen Intel CPUs are known to run significantly hotter than previous generations due to: By using specific parameters inside your boot configuration,
Note: AMD RX 6700/XT, RX 7000 series (RDNA 3), and all NVIDIA RTX cards are completely unsupported in modern macOS. Step-by-Step Configuration Strategy
agdpmod=pikera : Essential if you switch to a dedicated AMD dGPU later, preventing black screens on display wake.
If your About This Mac shows or 8MB of VRAM, you failed. You should see 1536MB . The framebuffer patching above must inject stolen memory correctly. If you see 7MB, your BIOS DVMT is still set to 32MB. Increase it to 64MB. Now we move from "it boots" to "it flies
This lack of support is a key point echoed across multiple languages and communities. A Turkish user on Technopat, after asking about his 12700K's UHD 770, was simply told "Hayır, desteklemiyor" (No, it doesn't support it). A German forum member with a Z790 AORUS ELITE AX and an i9-13900K was told his setup wouldn't work because "weder die Nvidia-GraKa, noch die interne UHD770 der CPU unterstützt wird" (neither the Nvidia graphics card nor the internal UHD770 of the CPU is supported).
