I wanted to run a newer KiCad but the OS on my Mac is too old. I figured why not try that OpenCore Legacy thing and see if I can put Sonoma on my late 2012 Mac Mini. No matter what I do though I can’t get past this. Every answer I find is either “figured it out” with no details; or superstitious “reset the nvram” Command-Option-P-R, or “reset the smc” (which is *extremely* superstitious: unplug the power cord for N seconds? Really?).
