: While you can technically boot into macOS by "spoofing" the CPU, you will be stuck with a basic VESA framebuffer. This is limited to low resolutions (often 1024x768 or similar) with no smoothness.
"The display flickers and the iGPU hits 80°C scrolling in Safari." Diagnosis: The memory clock was locked at 3200 MHz (Gear 2) but the iGPU was trying to use Gear 1, causing memory controller contention and thermal runaway. Fix: Lowered DRAM voltage from 1.4V to 1.35V and set forceRenderStandby=1 via boot-args. Result: Max temp under load: 68°C. Idle: 45°C (acceptable for 5K output). uhd 770 hackintosh hot
“Hackintosh is dead,” people said. “Just use Linux.” But Marco had heard that before, back in the Sandy Bridge days, back when we booted with Chameleon and prayed for QE/CI. He was a believer. : While you can technically boot into macOS
| Setting | Change to | Why | | :--- | :--- | :--- | | | Disabled (if using dGPU only) | Prevents the iGPU from rendering a phantom display. | | RC6 (Render Standby) | Enabled | Allows iGPU to power gate when idle. Crucial. | | GT Voltage Mode | Adaptive (not Override) | Drops voltage to 0.7V at idle instead of fixed 1.1V. | | Primary Display | PCIe (if dGPU) or IGPU (if only UHD 770) | Avoids auto-switching confusion that wakes the iGPU. | | Above 4G Decoding / Resizable BAR | Enabled | macOS handles this fine, but disable CAM (Clear Access Memory) if present—it conflicts with iGPU frame buffer. | Fix: Lowered DRAM voltage from 1
: Widely considered the "sweet spot" for modern Hackintoshes due to native support in recent macOS versions.
Intel UHD 770 (Alder Lake, Raptor Lake) and all newer Xe/Arc graphics are entirely unsupported.
