Hi Tony,
I must have missed the post about plotting "gores", do you still
have copies of the thread?
I'm not so sure about Mac GlobePlotter but how about a freeware
3D modeler/raytracer for the Mac?

Once you have the object modeled you can apply (wrap) a 2D image
of the world to it, voila, you just created the world! There is a freely
available 2D world image (texture map) from Science Simulations:

I just recently finished a 3D model of a horizontal dial with
its hour lines projected out to intersect the meridian lines of the
celestial sphere. It worked perfectly. It is a good illustration of
intersecting Great Circles and "why" the hour lines of the dial form the
angles they do for different latitudes. The URL below will take you to
the image.
