I took handouts. Mine last year said "We have to rent the digital projectors so don't ask unless you honestly need them!" I mean, someone in your panel might have one already, but if you haven't asked they probably haven't made provision for you.

However, you would need the little cable that came with your mac notebook that has a standard video connection on one end and a mac-friendly video connection on the other. It will hook to the regular video cord of the projector.
