@Jazzoo tried on mine but no graphic acceleration. slow & sluggish.

 

@Helphy do you mind sharing what you did with the config.plist sir?

Nevermind, finally I had macOS 12.5.1 Monterey working on i7-6600u latitude 7480. Edited the config to intel hd520 (based on someone's config. I thinkits from Jake Lo) for graphic acceleration. Still work in progress as the Thunderbolt port is not working. Only power mode for now.
