## What it is
PureDarwin is a community project that extends Darwin, Apple's open-source operating system core, into a complete, usable operating system. It aims to provide bootable ISO and VM images of recent Darwin versions.

## Use cases
- run a minimal Darwin OS without macOS
- boot Darwin in a virtual machine
- study the open-source core of macOS
- build Darwin from source on macOS
- experiment with an OpenDarwin successor

## When to choose
- you want to run or explore Darwin outside of a full macOS install
- you need a bootable Darwin ISO or VM image for testing or research
- you want to contribute to or study Apple's open-source OS components

## When to avoid
- you need a full desktop OS with GUI apps and drivers for daily use
- you want to build on Linux or Windows - it only builds on macOS with Xcode
- you need production support or a stable release cycle

## Facets
- artifact type: application
- maturity: active
- function: developer-tools
- domain: operating-systems, developer-tools
- platform: cross-platform
- tags: darwin, bootable-iso, vm-images, apple-open-source, kernel, operating-system, macos
