Apple Silicon
Apple's family of ARM-based processors for Macs, starting with the M1 in 2020; replaced Intel in the Mac lineup.
Apple Silicon refers to Apple's custom ARM-based systems-on-chip designed for Macs. The M1, M2, M3, and M4 generations and their Pro / Max / Ultra variants are all Apple Silicon. Every Mac shipped since late 2020 (except certain Intel-only stragglers) uses Apple Silicon.
Apple Silicon brought a unified architecture across the Mac, iPhone, and iPad: same instruction set, same Secure Enclave. For the secondary market, this means every Apple Silicon Mac sold has the cryptographic primitives Macfax depends on: per-device keys generated and held in the Secure Enclave, hardware-rooted signatures that don't leave the chip, and binding-by-hardware that survives factory resets.
Apple Silicon also makes case-swap fraud more lucrative than it was during the Intel era: the M3 Ultra in a Mac Studio is worth roughly five times the case it sits in. Verification matters more for these devices, not less.
Macfax requires an Apple Silicon Mac running macOS 14 or newer.
Secure Enclave
A separate security coprocessor inside Apple Silicon and T2-equipped Intel Macs; holds private keys, performs cryptographic operations, and is inaccessible from the main OS.
T2 Security Chip
A dedicated security and controller chip Apple shipped in Intel Macs from 2017 to 2020; it provides Secure Boot, encrypted storage, and a Secure Enclave.
Case-swap fraud
A fraud pattern where a Mac chassis with a valid external serial is sold with swapped internal components, usually a stolen or downgraded logic-board.
