Sorry I don't have a PC.
As you know, modern x86-based Macs are technically PCs, equipped with several Apple-specific components, in an enclosure whose design negatively impacts reliability, and a high price tag
I have worked with such a machine in a past day job, and seen others' experiences with their Macs.

That one's trivial and has been known, publicly documented since 2009, in a matter of hours or days after the boot2 was first decompressed
Unlike another offline method developed later, it requires a emulator in working state, and on the CX/CM, a copy of the boot1. But that method is less user-friendly nevertheless.
Amusingly, four suitably aligned zero bytes make one quasi-NOP on an ARM processor running in ARM mode, one quasi-NOP on a 68k processor, and four NOPs on a Z80/eZ80. Both the ARM and the 68000 have explicit, nonzero NOPs.
