I just noticed that running IE5 (Classic) in OSX I can see viewpoint content. This wasn't the case previously. Anyone else noticed?

You can, in fact, view most content in Classic mode on OS X. Future versions of the Mac VMP will improve upon the content that can be viewed. Eventually, we will have an OS X specific version of the player.

This solution is not for the consumer, but useful for developers. It's obviously not ideal to tell your user to boot a "classic" browser in OS X when they have carbonized browsers they use daily.

It is possible, but not supported by Viewpoint.
