A have installed macOS Ventura, but when I try booting up it just make a kernel panic. The image is original from apple and the EFI is full customised for my PC. Right now I'm using Catalina trying to update to Ventura. Help me please
Sorry for any English error, I'm Brazilian

Hi - I am not familiar with your platform but I took a look at your EFI Folder and found a glaring mistake, Lilu.kext must always be first before any other kext in the kext tree in the config.plist, the machine simply will not boot successfully.

I also took the liberty to update OC to the latest version as well as the kexts. Try the attached amended EFI Folder and see if the situation is better than before. Good luck.
