X11 2.7.7 has been released
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.
Download XQuartz-2.7.7_rc1.dmg, and open it with OS X's Installer.
OS X Requirements
OS X 10.6.3 or later is required to install this package.
Default X11 Server
If this is your first time installing XQuartz, you may wish to logout and log back in. This will update your DISPLAY environment variable to point to XQuartz.app rather than X11.app. If you would prefer to keep using X11.app as your default server (you can still launch XQuartz.app manually), you'll want to disable /Library/LaunchAgents/org.macosforge.xquartz.startx.plist using launchctl(1).
