Public registry

Compromised serials.

A continuously-updated list of Mac serials known to be compromised: reported stolen, flagged as tampered, subject to an insurance loss, or otherwise no longer in a trustworthy state. Macfax automatically checks every attested Mac against this list and refuses to issue a report on a serial that appears here.

Automatic enforcement

Every Macfax report checks this list.

When a seller runs Macfax, we read the Mac's serial in the first second of the diagnostic and compare it against the registry. If the serial appears here, we refuse to issue a report. No charge, no exception. Buyers checking a report URL also see the registry status next to the report ID.

C02ZW7QJX8WV → not on the registry · safe to issue

C02XF8K1J9G3 → on the registry · report refused
