ravynOS
Finesse of macOS. Freedom of FreeBSD.
ravynOS is an open-source operating system based on FreeBSD, CMU Mach, and Apple open-source code that aims to provide the finesse of macOS with the freedom of FreeBSD. It brings many features from macOS such as clean design, global menus, and drag-and-drop installs. ravynOS supports FreeBSD ports and apps, Linux apps, and even trivial Darwin & macOS binaries. The project is actively being developed and welcomes contributions from the community.
