Im on 10.12.6 with 660 gtx and just bought a RX580. Im trying to install High Sierra from the app store before I swap the cards out. This is the error im getting.

What could it be?

I got it to work... Not sure what did it but... In clover config i check fixshutdown and fixheaders. Then in the clover boot options drop Mats tables
