“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.
Recent advancements have shown that through careful configuration of your OpenCore config.plist , you can achieve .
The UHD 770 Dilemma: Why Your 12th/13th Gen iGPU is "Cold" in macOS
"My UHD 770 runs at 62°C idle with a Noctua NH-D15. The room feels hot." Diagnosis: The user had igfxonln=1 in boot-args and AAPL,ig-platform-id set to 00009B3E (invalid, defaulting to high performance). Fix: Removed igfxonln=1 , switched to 07009B3E , and enabled RC6 in BIOS. Result: Idle temp dropped to 38°C. VRM temps dropped 15°C. uhd 770 hackintosh hot
AMD Radeon RX 6600, RX 6800, or the legendary RX 580.

First, let's address the elephant in the room. The UHD 770 is not a powerhouse. In Windows, it is a competent desktop and media decoder. In macOS, however, it is a diva.
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:
While you can technically boot macOS on a system with these CPUs, you will have (QE/CI). This results in extreme lag, visual artifacts, and a non-functional interface (e.g., no transparent dock). 🛠️ The Only Real Solution: Add a Dedicated GPU Fix: Removed igfxonln=1 , switched to 07009B3E ,
