I have a Chinese mini pc xcy x43. I installed catalina but igpu only uses 7mb. This integrated graphics is the main one, there is no video card
I tried to change the AAPL, ig-platform-id, device-id and other parameters according to some tutorials. But with them, either macOS did not want to boot, or nothing changed
I also removed the boot parameter -igfxvesa, changed SMBIOS to iMac19.1. The config is standard from the theme with macOS versions
P. S. Sorry my english
