Adding a supported AMD graphics card completely bypasses the UHD 770 limitations. You will use the Intel CPU for processing and the AMD card for all display outputs.

If you own a compatible AMD dGPU (RX 6600, RX 6800, RX 6900 XT), you should use the UHD 770 for display output. Instead, use it headlessly .

According to Dortania’s GPU Buyers Guide , all UHD Graphics for 12th, 13th, and 14th Gen Intel processors are technically because they are based on the Xe architecture rather than the older UHD 630 (Coffee Lake) architecture.

If you are planning a build or trying to get your current UHD 770 system fully operational with macOS, this comprehensive guide covers everything you need to know about the current compatibility status, workarounds, and best alternatives. The Reality Check: Does UHD 770 Work in macOS?

This is the technical heart of the build. You need OpenCore 0.9.0 or newer. Here is the standard config.plist patch used by the community.

(e.g., RX 580) for a budget-friendly option.

(Crucial for video patching and managing your AMD dGPU)

If you have a supported AMD dGPU for your display, you can still use your UHD 770 in "headless" mode. In this configuration, the iGPU handles background tasks like QuickSync video encoding/decoding while the AMD card drives the actual monitors. This requires specific configuration using spoofing to mimic older, supported Intel architectures. Technical Challenges with 12th/13th/14th Gen CPUs
