Since I don’t have the original sales receipt of this specific Mac, I assume this option isn’t possible, since anyone with a stolen Mac could get the password reset. The normal process workflow is to first contact Apple support.
My preliminary research found references to a “magical” SCBO file that could be loaded onto a USB flash drive and booted to remove the password.
My original goal when I started poking around Apple’s EFI implementation was to find a way to reset a Mac‐ Book’s firmware password.
