There are several reasons why changing the serial number on a MacBook M1 is not feasible or recommended:
These tools communicate directly with Apple’s internal servers to configure the new logic board.

Given the prevalence of outdated information online, it's worth explicitly listing methods that are compatible with Apple Silicon Macs:
: If you are unsure if your M1 is new or refurbished, you can verify its status via Apple Support rather than attempting a serial change. macbook m1 change serial number
: Critical services like iMessage, FaceTime, and the App Store rely on a valid, Apple-verified serial number to function.

: If your Mac was repaired at a non-authorized shop, they may have used a used logic board from another machine, resulting in a serial number that doesn't match the one engraved on the bottom case.
