Some users attempt to change serial numbers to bypass Mobile Device Management (MDM) enrollment or iCloud Activation Locks.

If you need to find or verify your serial number rather than change it: How to change MacBook M1 Mode serial number

Unlike older models, changing the serial number on an M1 MacBook is considered highly difficult and is generally not possible through software alone.

With the introduction of the M1 chip in 2020, Apple moved away from standard Intel architecture and integrated the security architecture directly into the System on a Chip (SoC). macbook m1 change serial number

The only scenario where an M1 MacBook serial number is legitimately altered or rewritten is during an official hardware repair.

Even if you were to somehow change the serial number, the mismatch between the chassis serial number (printed on the underside of the MacBook) and the system serial number (stored in firmware) would be immediately detectable by Apple's diagnostics. This would prevent access to iCloud services, FaceTime, iMessage, and Apple Pay, and would also block any future warranty or repair claims.

Furthermore, the consequences of unauthorized serial number tampering on M1 devices are severe. Unlike their Intel predecessors, M1 MacBooks rely heavily on a secure enclave for operations ranging from Apple Pay to data encryption. Tampering with the device's identity can sever the trust between the hardware and Apple's servers. This often results in a "bricked" device that cannot receive firmware updates, run certain software, or utilize iCloud services. The risk extends to the software ecosystem; software licenses tied to specific hardware IDs can become invalid, leaving the user with a machine that is functionally impaired.
