From GhostBSD Wiki
GhostBSD is a Unix-like operating system based on FreeBSD, with MATE as its default desktop environment (GNOME was the previous desktop environment and XFCE). It aims to be easy to install, ready-to-use and easy to use. The project goal is to combine security, privacy, stability, usability, openness, freedom and to be free of charge.
