The current version of OpenCore doesn't work with 12500H very well. It only passes the boot.efi handoff stage if you either disable Hyperthreading or disable all E-cores. In my testing, disabling Hyperthreading lead to better performance. (Track issue: https://github.com/dortania/bugtracker/issues/336)
