Macbook Pro 2011 8,2 Big Sir non-metal issue with Opencore 0.4.2

Original OSX was High Sierra, and have time machine to network server. Used OpenCore 0.4.6. Modified the USb installer.

Doesn't finish the install, and gets to the last minute of the upgrade and hangs. If I stop it, the partition becomes corrupt.

Anyone install Big Sir on this model without metal graphics? Not sure where to go from here. I have done a couple, but never this issue.

Thanks in advance for any help !

Ok, this time something a bit different. Forced it off, and have errors about being unsupported. I attached a pic of what I have

So we modify the USB ? Install, and then it "should" boot into the OS right ? I can't get an install to finish?
