There is a free program called     Orbits,  written by
Stephen Eubank, Buff Miner, Jim Wiley, Toshi Tajima
Institute for Fusion Studies
Physics Department
University of Texas
Austin, Tx.  78712

and obtainable from Dr. Eubank, which works on most Macs; it permits
the simultaneous plot of trajectories from several initial conditions and
has in its distribution files examples of well-known dynamical systems and
iterated maps.. pendulum, Duffing, Rayleigh, ... Henon, standard, Ushiki,...
It probably is available somewhere by ftp, since it is redistributable [intact]. 
Another good program (I do not know how it is distributed) for Macintosh has
been made available to Universities:
DEGraph   differential equation solver and grapher, by
Henry C. Pinkham, 
Mathematics Department
Columbia University
New York, NY 10027.
