Summary

A Darwin/FreeBSD-based operating system developing macOS-compatible APIs, Cocoa frameworks and a familiar desktop.

Description

An operating system targeting macOS application interfaces and familiar desktop workflows on x86-64 hardware. Builds on Darwin, FreeBSD, public Apple source and independent compatibility frameworks, including Cocotron-derived Cocoa implementations. Develops AppKit, graphics, WindowServer and desktop components, aiming for application source compatibility and eventual binary compatibility.

Known limitations

Pre-alpha. General macOS application execution is not ready; upstream reports only trivial command-line binaries running. Current Darwin bring-up is incomplete, with missing framework APIs, desktop services and hardware drivers. Targets x86-64; ARM support is a future goal. Components retain their individual licenses.
