Here is how to set up iPhone or iPad as a remote control for a presentation on a Mac. Your iPhone is the perfect Keynote remote control for speakers, students, teachers and lecturers. You can start the presentation, advance to the next slide, go back to previous slides, end the presentation right at your fingertips. In this way, you can deliver your presentation with confidence and have the freedom to move around without having to return back to your computer o laptop for Keynote control. If you need to give presentations using Keynote on Mac and you have an iOS device as well, you can link your iPhone to Mac in Keynote and transform your phone into a Keynote remote control.
