Fix Intel UHD Graphics 620 (Whiskey Lake) on Laptop
macOS supports a wide range of Intel HD Graphics (also referred to as iGPU) but some of them might not work out of the box.
This guide will enable Full QE/CI on your Hackintosh. This fix is for the Hackintosh users who are using Intel HD Graphics as the main GPU.
Before you start with this guide, please know something about the performance. Graphics enhance the performance and helps to work smoothly. In macOS, full acceleration requires that both Quartz Extreme and Core Image (QE/CI) should work together.
Quartz Extreme and Core Image (QE/CI) should work together to enable full acceleration on macOS’s GUI. It utilizes the complete Graphics capabilities. In case if you haven’t enabled QE/CI on your graphic card, you won’t be able to use your macOS smoothly and there would be lots of lags and artifacts, graphic related issues and poor refresh rate. Also the dock would not be transparent. Therefore it is very important to ensure that your graphic is working with full QE/CI.
Requirements:
- Intel UHD Graphics 620 (Whiskey Lake)
- Original Graphics kexts in S/L/E
- macOS Mojave 10.14.6 or later
