Because the UHD 770 has more Execution Units (EUs) than the spoofed UHD 630, simply changing the ID is insufficient for hardware acceleration.
AMD's Radeon Polaris, Vega, and Navi series cards have native drivers built into macOS and are the standard for modern Hackintosh builds. This is the approach taken by virtually all successful Alder Lake and Raptor Lake Hackintoshes.
or, for native graphics performance without a dGPU, use an older Intel generation (10th Gen Comet Lake) supported natively by uhd 770 hackintosh
When Apple announced its transition to Apple Silicon in 2020, development of new Intel graphics drivers effectively ceased. The UHD 770, which first appeared with 12th generation Alder Lake processors, arrived after Apple had already committed to its ARM-based future. Consequently, no macOS driver ever existed for the UHD 770.
For a long time, there was no hope at all. However, a new community project is breathing some life into the possibility of unsupported Intel graphics on macOS. Because the UHD 770 has more Execution Units
Apple's last Intel-based Macs shipped with 10th generation Comet Lake processors. These machines — such as the 2020 27-inch iMac — featured integrated graphics from the UHD 630 family. Apple wrote and maintained drivers for these iGPUs because they were part of actual shipping products.
In the Hackintosh world, "spoofing" is a technique where you trick macOS into thinking your hardware is a different, supported model. For example, many users have successfully spoofed an unsupported HD 4600 to a supported HD 4400. While this is possible for the UHD 770 (by injecting a device-id to pretend it’s a UHD 630), the outcome is disappointing: at best, you get a basic, unaccelerated display signal. or, for native graphics performance without a dGPU,
The UHD 770, found in Intel's 12th, 13th, and 14th generation processors, is a more advanced GPU that was never used by Apple in any Mac model. Since Apple no longer relies on Intel for its processors, it has no reason to develop a driver for this newer iGPU. Consequently, macOS cannot identify or properly communicate with the UHD 770, leading to a system that will either fail to boot or will only function with basic, unaccelerated display output.
