If you're like me and present a lot via Microsoft PowerPoint 2011 on your Mac remotely, you have no doubt run into challenges when displaying presentations while either connected to a projector or web based meeting. If you simply want to mirror your presentation so you see what remote viewers see, this can be a little tricky. There's an option called Mirror Show and it's only available via the Ribbon toolbar, not in the SlideShow drop down menu. If your Mac adjusts to a low resolution due to the projector, this toolbar actually gets hidden. So, what do you do? Set this option prior to connecting to anything (projector or remote).
