Will all the templates work on PowerPoint for Mac?
Absolutely! All PowerPoint for Mac users can also use these templates -- and since all downloads are actually ZIP files, you should have no problems at all.
Remember -- all new Macs now include in-built ZIP support -- so all you need to do now is double-click a downloaded ZIP file, and within seconds, you'll see a folder of the same name.
Inside the folder is a POT file that you can open in PowerPoint 98, 2001, X, and 2004.
