Reader Dustin Flatt is flat out of ideas about connecting his MacBook to a projector. He writes:
My roommate has a MacBook Pro and I own a MacBook. The Pro can be hooked up to our projector and we watch movies. My laptop does not have a port for the projector. I was wondering if there is something I could buy to have a port for my MacBook. If so, what is it called? How much? And where can I get it?
If you want to connect your MacBook to the projector via VGA, you need Apple's Mini DVI to VGA Adapter. It costs US$19 and you can get it at any Apple Store or the online store, using the link I just provided. If that projector has a DVI port, you can use Apple's also-$19 Mini-DVI to DVI Adapter. A DVI connection will look better. The mini side of the cable plugs into the port sandwiched between the Ethernet and FireWire 400 ports.
Note that you'll also need a cable that runs from the adapter to the projector. It's possible that you'll be able to use the one your roommate uses with his or her MacBook Pro. Or there may be one in the projector box.
