Does authorstream/powerpoint work with Mac?

If I upload my powerpoints with narration to Authorstream.com will my students who use a Mac be able to access them? I would ideally like to just embed them into my own website. If so will they still have the narration/animations? If I convert them to flash will that allow them to see them? If not how can I give access to my powerpoints to students who use a Mac in the simpliest way possible.
