Want to hook up your new Mac directly to an HDMI-equipped HDTV? You’ll need an adapter. Apple isn’t selling them, but that doesn’t mean they don’t exist.
Amazon and through its partners are now selling the adapter cables for $19 plus $4.99 shipping. Gizmodo ran some tests on the Mini DisplayPort-HDMI adapter and found it worked better than Apple’s solution of Mini DisplayPort-DVI Adapter to DVI-HDMI adapter. Plus this one is cheaper.
Monoprice has them for less but they are currently on backorder.
