The Problem

Buying a used Mac
is a trust problem.

The $12B used laptop market operates on descriptions and photos — both trivially fakeable. Sellers and buyers lose time, money, and trust every day.

😰
For buyers — today without ClariMac
  • Mac listed from overseas as "local" — doesn't exist
  • Seller hides battery at 38 cycles, actually 3,200
  • iCloud activation lock not disclosed — brick on arrival
  • MDM enrolled by a corporate — can't be removed
  • SSD at 89% health, described as "perfect condition"
  • No way to verify — you rely on photos and trust
With ClariMac
  • Seller location geo-confirmed at scan time
  • Battery cycles, health — exact, machine-reported
  • Activation Lock status — verified, shown in red if locked
  • MDM enrollment — disclosed, flagged
  • SSD health % — real data, not a description
  • Blockchain-anchored — impossible to alter after publish
The Solution

Two ways to transact.
One trust standard.

ClariMac supports both local in-person transactions and remote online sales — with different levels of trust assurance for each context.

📍 Local mode
Meet in person.
Transact with proof.

Buyer and seller meet face-to-face. The cert was generated from the exact location where the meeting happens — the Mac exists, it's here, it's real.

📍
Geo-fencing confirms Mac was scanned locally — not from Dubai or a stock photo
🤝
Buyer scans QR code on cert before handing cash — real-time verification
🛡
47-point hardware report eliminates verbal disputes about condition
No escrow, no platform fee — direct transaction with verified proof
🌐 Online mode
Sell anywhere.
Ship with confidence.

Seller posts the ClariMac cert link with the listing on Kijiji, FB Marketplace, or eBay. Buyers verify the report before sending payment.

🔗
Shareable permanent link — paste it in any listing description
🔍
Buyer verifies via serial number or report ID — free, instant, no account
Blockchain anchor proves report was not modified after publishing
📈
Certified Macs sell 30–40% faster, often at higher price
Geo-fencing — Anti-scam layer

The Mac can only be listed
where it physically exists.

The single biggest scam in used Mac sales: listing something that doesn't exist locally — or at all. Geo-fencing eliminates this at the hardware level.

1
Scan — hardware + location captured together When the seller runs ClariMac, the app records 47 hardware metrics AND the device's GPS coordinates at that exact moment. The location is embedded in the signed payload — not editable.
2
Cert published with a location radius The cert shows "Québec City area" — not the seller's exact address. Buyers know the Mac is in their city. Cross-country or international fake listings become impossible.
3
At meet-up: buyer scans QR → verifies live The buyer opens the cert on their phone before handing money. They see the location matches where they're standing. No way to fake a Montréal listing from Lagos.
4
Future: app-attested location (iOS/macOS) The next version uses Apple DCAppAttestService to cryptographically prove the location came from a real device — not spoofed GPS. Unhackable location proof.
Common scam scenarios
🚨
Ghost listing — item doesn't exist

Seller posts stock photos of a MacBook Pro, says it's in Québec. Asks for e-transfer deposit. Disappears.
→ With ClariMac: cert requires a real scan on a real Mac. No scan = no cert.

🚨
Remote listing — seller is overseas

Scammer lists Mac as "Montréal local pickup" from Nigeria. Offers to "ship." Payment sent, nothing arrives.
→ With ClariMac: cert geo shows Montréal. Overseas scan = different location = red flag.

ClariMac certified listing

Cert shows: MacBook Pro M2, 8/512, battery 94%, Québec City area, scanned 2026-05-28. Location matches meet-up address. QR verified on phone. Safe to pay.

Technology

Built on infrastructure
no competitor has.

Three layers of trust that individually exist — but nobody has combined them for used Mac transactions.

🔑
Apple Secure Enclave

The hardware scanner runs inside the Mac's Secure Enclave — a tamper-proof chip. The 47-point report is signed with a P-256 key that never leaves the hardware. Impossible to spoof from a VM or Hackintosh.

DCAppAttestService
📍
Geo-fenced Listing

Location is captured at scan time and embedded in the cryptographic payload. The listing location is machine-verified, not seller-declared. Eliminates ghost listings and cross-border scams at the source.

GPS + Attestation
Solana Blockchain

The report SHA-256 fingerprint is anchored on Solana at publish time — 65,000 TPS, finality under 1 second. Any modification to the cert after publish breaks the hash. Public, immutable, permanent.

Market Pricing Engine

116 Mac models across 4 condition tiers (used, Amazon, Apple refurb, Reebelo refurb). Grade-aware pricing: A=p75, B=median, C=p25, D=min. Real-time market context with every cert.

110+ models · Grade-aware
🌐
Decentralized Architecture

The cert is anchored on a public blockchain and verifiable by anyone with the report ID — no ClariMac account required. If ClariMac disappears, every cert remains verifiable forever via the Solana explorer.

No single point of failure
Market Opportunity

A global market with
zero trust infrastructure.

The secondary electronics market is growing 15% YoY worldwide. Used Macs hold their value better than any other laptop — and have zero certification standard today, anywhere.

Business Model

Three revenue streams.
All defensible.

Transaction fees, subscription B2B, and data — each layer grows with the network and reinforces the others.

Phase 1 — Now
Per-cert fee
$9.95 / cert

One-time payment. Seller pays to generate a permanent, verifiable cert. No subscription. No friction.

  • $9.95 per report — direct revenue
  • Margin >90% (server + Solana tx cost)
  • 100 certs/mo = $995 MRR — no staff
  • 10,000 certs/mo = $99,500 MRR
Phase 2 — B2B
Workshop & API access
On request

Mac shops, refurbishers, resellers — and automated agents — certify inventory at scale. Dashboard, co-branded reports, programmatic API.

  • Tiered plans for volume certification
  • Full API for programmatic / agent access
  • Co-branded reports + reseller badge
  • Contact for pricing →
Phase 3 — Platform
Marketplace + data
2% take rate

Geo-fenced certified listings marketplace. Buyers and sellers transact on ClariMac — we take a small percentage of completed sales.

  • 2% of GMV for completed sales
  • Pricing data API for insurers + lenders
  • Aggregate market intelligence
  • Lead gen for repair shops
Roadmap

From certification to
full trust marketplace.

Each phase builds on the last. The cert is the foundation — geo-fencing, live pricing, and the marketplace are the network effects that compound.

Why this can't be copied
in 6 months.

Each layer is individually available — but the integration requires Apple developer relationships, blockchain infrastructure, and market-specific pricing data that takes years to build.

🔑 Apple Developer Relationship

DCAppAttestService requires Apple approval and a published macOS app on the App Store or with a Developer ID. The attestation key is hardware-bound — replicating this requires the same relationship, the same engineering, and the same Apple review process.

📊 116-Model Pricing Database

Four data sources (Amazon, Apple refurb, Reebelo, private sales) cross-referenced against 116 specific Mac models with RAM variants. Grade-aware percentile pricing. This dataset took months to build and is continuously refreshed.

⛓ Blockchain Infrastructure

The Solana integration through DataMirror gives every ClariMac cert a permanent public record. The cert network has a first-mover advantage — older certs are more trustworthy because they've been live longer with no disputes.

🌐 Network Effects

Every certified Mac sold becomes a ClariMac reference. Buyers who verify a cert become aware of ClariMac. Sellers who get 40% more for a certified Mac tell other sellers. The marketplace liquidity compounds — more certs = more trust = higher prices = more sellers.
