Hi @MaLd0n, ignore the previous post.
I performed my configuration, and used a user's complete EFI folder here from the forum.
the only thing that is not working is the camera, headset via the p2 connection and the trackpad.
I would like you to check if everything is ok, I am still reading and better understanding this world of dsdt and the like.
Thank you so much.
