Disclaimer

You cannot use this EFI as it is.

At least you have to change your Serial Number, which is located in EFI/OC/config.plist, search for PlatformInfo, look for keys: MLB, ROM, SystemSerialNumber, SystemUUID. It’s super easy, more on that in Dortania‘s guide.

Maybe you have to check for other things, if you have different hardware, e.g. iGPU instead of dGPU. Don’t hesitate to ask if you have any questions.
