I got a available sierra installed on a Gateway NV57H I used the a mix of the generic information install and the HP signature install guide since there is not much info avaliable for this laptop. The graphics are not loading properly it has the correct screen resolution but in the system information app under graphics it says no kext loaded. I had to make a custom config.plist because as I said before no one really has made a hackintosh out of this laptop Problem Files folder attached....
