making Mac powerpoint presentations compatible for windows

Having recently purchased a Mac for the first time, I'm struggling a bit with the fact that although I'm preparing powerpoint presentations (with music) on it, I can't play these presentations in a windows PC. I also received today a song in .m4 format, and it won't open on my Mac. Anyone know how I can do these things?

Apple Mac, Mac OS X (10.6.4)

Hi. I only tried one Powerpoint presentation. On Mac it saves as a 'pptx file, which doesn't play in windows. It said something like it wasn't recognised. Someone else says I need I-Work to do it properly. I'm not that computer literate, and as you can see by the time lapses of my entries, I don't have the time to devote to it. I'm really disappointed, because other Mac users swear by Apple, but it's all a bit bewildering to me. I think I'll have to sign up to a tutorial. I CAN go back to the Apple shop for some 1 to 1, but I haven't got around to it yet. It's 30 miles away, and I work, so it's tricky. I had no problems with the windows PC when I bought it first - the instructions were crystal clear. I don't know about the ones for the Mac - I find them rather obscure. I have a friend who used keynote, and that didn't play in windows either. She had to redo the whole thing on the windows pc.

Oops, this might be it. The pptx format is new with Office 2008 (Mac) and Office 2007 (Windows). For older versions, Microsoft provides a free update that will read these formats. I bet the Windows machines you are using are running an old version of PowerPoint without the proper updates.

Lizzie, yes you can do it! When you save your presentation, you have options under "save as" and one of those is the older version of power point (ppt). This will be the only step you need if you want to save a powerpoint without media files.

To save one with media files, choose "save as presentation." It will give you a handy little folder with both the powerpoint and the media file. In this option the power point automatically saves as pptx, however. So, open it, save it as older version. Presto problem solves. The issue is not mac 🙂
