Using X11 with OS X

Installing X11

How to intall X11 depends on what version of OS X you have installed:

10.2 and earlier

No official versions of X11 exist for these versions.

10.3 (Panther)

X11 is available from Apple's website

10.4 (Tiger)

X11 is an optional installation from the Tiger DVD.

10.5 (Leopard) and later

X11 is installed by default.

Running X11

Recent versions of OS X will automatically launch X11 when a program attempts to connect to the X server. Open Terminal.app and try running xterm. If that doesn't work, you'll need to start X11 manually. It can be found in /Applications/Utilities.

Using X programs from the CS machines

Using the Terminal or an xterm, use ssh -X username@hostname to connect to a CS machine. Once logged in, you may use programs as normal. For example running emacs should open the emacs window on your computer.
