Sandy Bridge High Sierra ERROR: OCS: No Schema for CpuidData at 0 index

Hello everyone,

I've followed through the Dortania OpenCore guide twice, trying to install MacOS High Sierra on my computer but ran into the following error on boot both times:

OCS: No Schema for CpuidData at 0 index, context <Force>!

OCS: No Schema for CpuidMask at 1 index, context <Force>!

OCS: No Schema for DummyPowerManagement at 2 index, context <Force>!

OCABC: Incompatible OpenRuntime r11, require r12

Halting on critical error

I'm running an Intel i7 2600k on an Asus p8z68-V motherboard with a GTX 1080 graphics card.

Any guidance is much appreciated!
