How to show a Keynote presentation on other platforms?
Solution 1:
From your Keynote document select:
File > Export > PPT...
or better (to avoid most problems with PowerPoint format):
File > Export > PDF...
This last format will work perfectly on any Unix and any Windows.
Warning: test these formats on the target system before a serious presentation.
With both formats, video, animation, transitions and presenter notes will be lost.
If your projector is of the VGA era (see https://www.google.fr/search?q=vga&source=lnms&tbm=isch) then I would advise you to:
- Stay with Keynote (this software is still many years ahead of many others and mostly of PowerPoint).
- Buy a Mini DisplayPort to VGA adapter.
Solution 2:
No - all the features require a Mac. You can get a large subset of most features if you transfer a Mac keynote to iOS and use it for presenting, but you'll have to dumb down your presentation substantially or render it as a movie to have it play on Windows.
Your best bet is getting the connector you need to have the Mac connect to the projector. Other than someone preventing me from physically accessing the projector cables, I've not seen a projector where a Mac couldn't be connected and a PC could be connected. Perhaps you have some strange situation, but most likely you can get connected with an inexpensive adapter.
