Hi MaLd0n, you did me a patch file for my pc but I never got the hd4000 gfx working, so I have started again from scratch and installed latest Mojave version, and my gfx card back in would you be kind enough to do me another patch and a copy of the EFI folder the config I have at the moment boots but there are lots of ACPI and cpu errors
thanks
