A: Then you are swapping the entire identity of the Mac. The serial moves with the M1 chip. You now have the same problem, just moved to a different shell.
This is incredibly high-risk. M1 Macs perform a hardware integrity check during every boot. If the serial number in the NAND doesn't match the signature in the Secure Enclave, the Mac will enter DFU mode and refuse to boot, requiring a full restore that will wipe all data and likely revert the serial number anyway. 3. Virtualization (The "Safe" Workaround)
This requires $10,000+ in equipment and years of experience. A single bridge pin short will permanently kill the logic board. There is no "undo" button.
Some researchers have tried to intercept the diagnostic port (JTAG/SWD) on M1 Macs. However, the debug features are fused off on production chips. Enabling them requires a laser-based fault injection (costly and unreliable).
