Most machines with a reasonable broadband connection will work reliably with ProtoSphere. If you are able to talk on Skype or watch videos online without buffering then you should be able to use ProtoSphere. At the moment you'll need to use Windows as there isn't a version for Mac OS yet. However, there will soon be a version that will run in a browser. Or you can run Windows on your Mac using Bootcamp. That's what we do!!
