Serial lookup · signed reports · listings

Sell with proof.
Buy with confidence.

Look up any Mac, iPad or iPhone by its serial and see exactly what it is. Sellers put a Mac on the record with a report the Mac signs itself, and buyers check that record before they pay.

Try a serial number, a model like MacBook Air M2, or a listing link.

Sell with proof

Put your Mac on the record.

Run the free Macfax app and your Mac produces a report it signs itself. Attach the link anywhere you sell, and a buyer can check it against the machine.

Identity, spec match, condition. A signed report in about a minute.

03
Put it on the record

Attach your report URL to any listing, anywhere you sell.

Signed at issuance

The report is signed by a key held inside the Mac that produced it, then hosted by Macfax. What a buyer opens is the canonical record.

Bound to the hardware

A report cannot be moved onto a different machine. Serial, chassis and logic board have to agree with the record.

Checkable on receipt

A buyer can re-verify the Mac against its record at the doorstep. The capability existing is what keeps everyone honest.

Listings

Every listing here is a record, not a blurb.

Macfax standardizes every Mac it lists, whoever is selling it, with the asking price in the open. Where a seller ran a report, the listing carries it.

Common questions.

Is Macfax a store?

No. We standardize listings from wherever Macs are sold and link you straight to the seller. The record is ours; the sale is theirs.

What does the badge mean?

A signed Macfax report is attached to that exact Mac. Open it from the listing and read what was checked, when, and by which machine.

What does it cost?

All of it. Browsing is free, the seller app is free to download and run, and everything it measures is in the report it publishes. There is no paid tier, no account and no card.

I am selling. Where do I start?

Download the app, run the free report, and attach the report URL to your listing wherever you sell. Get verified when you want the badge on the shelf.
