I have created a Microsoft PowerPoint 2003 presentation (a .ppt file) using Windows XP. My colleague has a Mac computer and PowerPoint for Mac. I would like to share my presentation -- including animations -- with my colleague. Is there a way that I can save my .ppt file to a form that PowerPoint for Mac can open, and retaining all animations?
Your file should be viewable on the Mac without issues, though there are some things you need to avoid. Motion path animations isn't a feature that exists on the Mac version, but it will play those animations in files created on windows. You just won't be able to edit that animation on the Mac.
You should also avoid embedding linked content and anything windows specific, such as WMV video. If you need to link to content, it may work if you put the file in the same directory before embedding, and then send both files to the recipient.
There is a lot of platform compatibility links, such as http://office.microsoft.com/en-us/powerpoint-help/cross-platform-powerpoint-compatibility-HA010287268.aspx and http://www.pptfaq.com/FAQ00281_PC_to_Mac_and_Back.htm
