Hi folks! Times goes fast. I have some new findings to share with you. Now it’s time to write a new post.
If this page looks strange due to font or layout issues, you can find a pretty-printed GitBook version at here.
>> Introduction
Nowadays, it might not be easy to make the integrated graphics card, namely Intel UHD Graphics 630, fully work on Apple’s latest macOS Mojave without any issues on a Coffee Lake-based laptop. In addition to the minimum requirement of DVMT pre-allocated memory that I identified three years ago, some built-in displays may not report valid values of certain capabilities, resulting in the graphics driver failing to verify those values and reporting a fatal error by triggering a kernel panic.
