Did you erase the disk first before like I suggested I my previous post?
Yes, every time. Just for interest, I also tried a build on another OCLP MacBook 9,1 successfully running 15.1 final with the host set to 7,1 and the SMBIOS spoofing set to moderate and the Spoofing Model to MacMini 8.1. It got further than in the previous 4 or 5 times but gave a similar error again. I think I'm going to sleep on it!
