Remote won't work with PowerPoint

That may well be the case, particularly with the older product. If you have Keynote, why not import the PP presentation and run it from there?

You can download a program called "Remote Buddy" and it extends the use of the mac remote. Its about $20, but I figure its that or I have to go buy another remote that works! Below is the website. I haven't used it yet, so I can't review how well it works, but tonight I am giving a presentation and will find out!

I use "Sofa Control" which has incredible functionality and is only $15
It is produced by "Gravityapps"
