austincloudguru Posted February 21, 2021 Share Posted February 21, 2021 I have been working through Dortania's OpenCore Install Guide and I have been able to get Big Sur installed on my Latitude 7400. Everything seems to work ok, but I have two graphics related issues that I can't seem to figure out. The main issue is that my display is showing up as external monitor, rather than the LCD panel that it is on. The other issue is that About My Mac only shows 7mb for my graphics card (Intel UHD Graphics 620). I've attached my config.plist file. Any help or pointers to go look at would be greatly appreciated. config.plist.zip Link to comment Share on other sites More sharing options...
austincloudguru Posted February 21, 2021 Author Share Posted February 21, 2021 I was able to find a good device configuration for my card and it is working now. I'm attaching my working config.plist in case anybody else might find it useful. uhd620-working-config.plist.zip Link to comment Share on other sites More sharing options...
