## Health v2 (maintenance only)
Score: 76/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 98, release rhythm 35, longevity 100
- inputs: {"age_days": 1731, "days_push": 17, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated collection of reverse-engineered Apple formats, protocols, and knowledge, including a machine-readable YAML database of Apple hardware. It is maintained by the hack-different community and rendered as documentation via Jekyll.

## Use cases
- find machine-readable specs for Apple hardware models
- learn about reverse-engineered Apple file formats and protocols
- research Apple Silicon internals for jailbreak development
- find tools for Mach-O binary analysis
- look up documentation on iOS and macOS internals

## When to choose
- you need structured YAML data about Apple devices or formats
- you are researching Apple platforms for security or hobbyist work
- you want a curated starting point for Apple reverse-engineering tooling

## When to avoid
- you need official Apple documentation or support
- you want a runnable software tool rather than a knowledge base
- your work depends on AppleInternal or DMCA-restricted materials

## Facets
- artifact type: dataset
- maturity: active
- function: reverse-engineering, documentation, data-science
- domain: reverse-engineering, apple-ecosystem, security, hardware, documentation
- platform: cross-platform
- tags: apple-silicon, jailbreak, awesome-list, yaml-database, jekyll, mach-o, community-resource, macos, ios
