If you use Stereo 3D on Mac OS X and are happily running Tiger, please do
not upgrade to Leopard yet. It seems that stereo 3D visualization is still
broken under Leopard 10.5.3.
If you are presently considering purchase of a Mac Workstation for Stereo 3D
Graphics visualization, then you may wish to defer your purchase for the
time being or go with Linux unless you can confirm for certain that Tiger
will indeed run on the machine you are buying, since you can't necessarily
expect older operating systems to install on newer hardware.
I have reconfirmed with my developer relations at Apple that they are aware
of the severity of the problem and have the issue appropriately prioritized.
Unfortunately, there is just a bit too much good stuff going on with Apple
