The Secure Enclave will detect a cryptographic mismatch, permanently bricking the M1 chip and rendering the MacBook completely useless. 2. Loss of iCloud, iMessage, and FaceTime

The technical difficulty of altering this identifier on an M1 MacBook has led to a polarization of methods, ranging from the official to the illicit. Officially, Apple uses proprietary internal tools (such as Apple Configurator and internal service portals) to transfer serialization during authorized logic board replacements. This ensures that the physical hardware remains authenticated. However, the high cost of official repairs has spurred a "right to repair" conflict. Unauthorized technicians often attempt to modify these numbers to circumvent Activation Locks or to mask the history of stolen devices. While software exploits occasionally surface that allow for the spoofing of serial numbers in NVRAM, Apple’s tight integration of hardware and software often results in these changes being temporary or triggering security warnings that render the device unusable.
