The company providing LCS glasses for the Mac provides software with their
system. It probably uses interlaced presentation, but I don't have specific
knowledge of the details. All the software has to do is to recognize that
JPS means JPG stereo, then it cuts the image exactly in half and processes
each half appropriate to the display method. 

If you use IE in your Mac, and the MRJ 2.1 from Apple, you can access JPS
images just like everyone else using the Stereoscope Applet, with the
exception of LCS support. There is an interlace option in the applet, and if
you have an external VGA pass thru device that interlaces the display image
(independently of the computer) and times the glasses, you could get LCS
stereo with the applet. I don't know if the Mac uses VGA to it's monitors,
or if similar external devices exist for the Mac.

There is a homebrew site on the net about circuits that you can build for
yourself that will drive LCS glasses for most kinds of systems. The site is
impressive, but I saw no specific mention of platform issues except that the
external VGA device seems the most universal of all the methods. If someone
has technical knowledge of the Mac and can comment on suitability of any of
the homebrew circuits, that would be great.

If the comments are of a technical nature, let's continue this on SD3D...
