ravynOS – Finesse of macOS. Freedom of FreeBSD.

We love macOS, but we’re not a fan of the ever-closing hardware and ecosystem. So, we are creating ravynOS — an OS aimed to provide the finesse of macOS with the freedom of FreeBSD.

ravynOS (previously called airyxOS) is an open-source operating system based on FreeBSD, CMU Mach, and Apple open-source code that aims to be compatible with macOS applications and has no hardware restrictions.

• ravynOS, Always

  We’re building familiar apps native to ravynOS, packaged as portable .app bundles and built with our core technologies of Cocoa, Qt, and Mach. These are guaranteed to work and fit seamlessly into your desktop.

• FreeBSD, Mostly

  FreeBSD ports that support Wayland continue to work on ravynOS right out of the box, or with minor changes.

• Linux, Sometimes

  Many Linux applications that support Wayland are expected to work with FreeBSD’s Linux emulation layer.

• macOS, Maybe

  Trivial macOS and Darwin applications may run directly on ravynOS. This is an active area of work and research. AppKit-based source code may build and run natively.
