Welcome to the RavynOS user and developer wiki!

The RavynSoft Open Desktop Operating System, otherwise known as RavynOS™, is an open-source desktop OS designed to look & feel similar to recent versions of Apple's macOS® and aims to be mostly compatible with it at a source, and eventually at a binary, level. The RavynOS project is still very young but is making rapid progress. For background and general info, screenshots, releases, and access to the source code, please check out https://www.ravynos.com/.

This wiki holds information for developers and users of RavynOS. It's still fairly new so please bear with us! If you would like to help document things or organize this wiki, please get in touch with mszoek on our Discord, Matrix or IRC channel.

If you have successfully run RavynOS on real hardware, please add your machine to the supported hardware list!

We want to make the best system possible! Tell us about macOS features you love and hate.

Developer Info

Development action is mostly on Discord and over at our GitHub. Need something to hack on, or just want to understand the plan? A (very) high-level Roadmap with areas needing work is available.
