The cryptographic handshake requires a valid Apple Service Provider account. No third-party tool can emulate this.
If your device is having serial number issues, rely on official channels. For more information, you can always check your current serial number via Apple's support guide .
The direct answer is On older Intel-based Macs, technicians could use proprietary Apple software like the Blank Board Serializer (BBS) to write a serial number onto a replacement logic board. However, Apple’s transition to M1, M2, and M3 chips fundamentally changed how device security and serialization work. macbook m1 change serial number
Some users inherit or buy used MacBooks that are locked to a school or corporate network via MDM, and think changing the serial number will bypass it.
Some advanced third-party repair shops in markets like Shenzhen use hardware programmers (like the JCID or Navipro tools). They physically desolder the NAND flash chip or use probe points on the logic board to rewrite the system configuration data.
The M1 MacBook, released in 2020, is a line of laptops developed by Apple Inc. that features a new Apple M1 system-on-a-chip (SoC).

The only safe and legitimate way to handle a serial number issue on an M1 Mac is to take it to Apple or an . These professionals have the authorized diagnostic software, known as the “Repair Assistant,” which is part of a secure process for pairing new logic boards to the chassis.
