The XQuartz project is an open-source effort to develop a version of the X.Org X Window System that runs on macOS. Together with supporting libraries and applications, it forms the X11.app that Apple shipped with OS X versions 10.5 through 10.7.
If you have upgraded to Yosemite, El Capitan or Sierra from a previous Mac OS and had XQuartz previously installed, then the upgrade causes the symbolic link to the X11 directory to break. This is a known issue with the Mac OS upgrade. Because Huygens depends on X11 in Mac, Huygens will not be able to run at first.

Important Info for 10.5 Users
OS X Software Updates have included some of the work done by the XQuartz project, but for various reasons, Apple cannot ship the latest and greatest version offered by the XQuartz site. Since the XQuartz X11 package clobbers Apple's X11.app, their software update will clobber the XQuartz X11 package. Because of this, you may experience conflicts after doing a Software Update from Apple. Please re-install the latest XQuartz X11 release for Leopard after installing a system software update to OS X 10.5.x Leopard.
