Hello, and excuse me for my late response.

I have looked into this question in the past, but I couldn't find a
solution without breaking the 'dimensions' option; with it, it is
possible to control the canvas size, which must be declared just when
the terminal is set. I think it is not possible to set the canvas
dimensions afterwards. (If I am mistaken, and someone knows how to do
that, please let me know.) Therefore, 'draw' needs to set the terminal
itself.

I understand that it's not comfortable to type terminal=aquaterm
everytime someone needs a plot in Mac, but it can be a bit painless
typing 

load("draw")$
set_draw_defaults(terminal=aquaterm)$

only at the beginning of the session.

There is at least one way to let Maxima know whether it's running under
Linux or Windows. If it were also possible to know if it's running on
Mac, 'draw' could set terminal aquaterm automatically.
