Norm,

First, I don't have an Intel Mac (you lucky guy). I have an old G5.

First, do you have X11 installed? It is on your OS X system DVD disk, hidden
away somewhere, waiting for your installation. With X11, you need to start
octave within an xterm, which opens automatically when you start X11.

In addition there is an X11.sdk, which is above and beyond the X11.app
installation. It applies bells and whistles to the X11 application. I don't
know when or if it is used, but I have it installed.

I don't know if aquaterm is available yet for Intel Macs. It is an
alternative to X11 that lets you do plots directly from a Mac terminal
session, without X11. There are arguments both for and against aquaterm, but
it is my primary plot output with octave.
