Welcome to the XQuartz project


The XQuartz project is an open-source effort to develop a version of the X.org X Window System that runs on OS X. Together with supporting libraries and applications, it forms the X11.app that Apple has shipped with OS X since version 10.5.

Latest Releases

Stable: 2.7.7 - 2014.08.18

Development: 2.7.8_rc1 - 2015.03.25


There are three ways to get support for XQuartz.

OS X Software/Security Updates and XQuartz (Leopard Only)

OS X Software Updates have included some of the work done by this project, but for various reasons, Apple cannot ship the latest and greatest version offered by this site. Since our package clobbers Apple's X11.app, their SU will clobber ours. Because of this, you may experience conflicts after doing a Software Update from Apple. It is suggested that you install the latest XQuartz release after installing an update to OS X Leopard.
