Terms of service

Last updated: 2026-05-04

Use of Macfax is subject to the terms below. By paying for a cert, downloading the macOS app, or running a buyer-side re-attestation, you agree to them.

What Macfax certifies

A Macfax cert is a snapshot, signed by the certified device, of the device's technical state at the moment of issuance. Specifically:

  • The device's serial, model, and hardware identifiers
  • The state of Activation Lock, Find My, and MDM enrollment
  • SSD wear, memory test results, CPU/GPU burn-in results
  • The cryptographic binding to the device's Secure Enclave key

What Macfax does not certify

Software cannot prove what software cannot read. A Macfax cert does not certify:

  • Cosmetic condition (dents, scratches, hinge wobble, screen burn)
  • Liquid contact indicators (LCI strips are physical, internal)
  • Whether the device has been opened (Macs don't expose this in software)
  • Apple repair history beyond the macOS Service History pane
  • Pending mechanical failures (no service can do this even with physical inspection)
  • The seller's identity, the buyer's identity, or the transaction itself

Cert validity

A cert is valid for 30 days from issuance. After that it renders with an expired status; the data is still visible but is no longer authoritative. Re-issuance is free for the same device within 14 days.

A cert may be revoked if a confirmed dispute (e.g., a buyer re-attestation revealing a different enclave key) is upheld. Revoked certs are recorded permanently in our internal record; the public cert page returns a revocation banner.

Buyer re-attestation

We strongly recommend buyer-side re-attestation on receipt. Mismatch between the cert's enclave key and the device's enclave key is the fraud signal we exist to surface. If you skip the re-attestation step and accept delivery, you've skipped the protection the product provides.

Liability

Our total aggregate liability under these terms, for any cause (including breach of contract, negligence, or otherwise), is limited to the $39 cert fee you paid. We are not liable for indirect, incidental, or consequential damages (including lost sales, lost transactions, fraud losses beyond the cert fee).

We are a verification product, not an escrow. We do not insure transactions, do not hold funds, and do not adjudicate disputes between parties beyond surfacing the cryptographic evidence on file.

Acceptable use

  • One cert per Mac per purchase. Bulk purchase tiers may exist later. Buying one cert and re-using it for a different device is a violation.
  • No tampering with the seller-side app or attempting to forge App Attest assertions. Either is grounds for revocation of all certs tied to the same email and a permanent ban from re-issuance.
  • Don't use Macfax for goods or scenarios for which it's not designed (lookup tools, jurisdictional services we haven't validated, etc.).
