Boot delay optimization for systems with both NVIDIA dGPU (RTX 3080) and driverless Intel iGPU (UHD 770) on macOS 15.8.1.
Achieving fast boot times and seamless GPU enumeration on macOS systems with mixed GPU configurations.
This issue identifies a significant boot delay (60s) caused by macOS's IOGraphicsFamily waiting on a driverless Intel iGPU, not the NVIDIA driver itself. The solution, hiding the iGPU via OpenCore's WhateverGreen and -wegnoigpu, dramatically reduces boot time from 137s to 28s. This highlights a c...
