Bests & Worsts Reviews from Amazon

This cable is well built and a great deal. Prior to ordering this cable however, you need to check a few things. First verify that your Mac actually outputs sound through the mini-display port. You can verify your specific model here- [...] Sorry, Amazon will not allow me to put in a direct link. Just go to the Apple support web site and enter "About Mini DisplayPort to HDMI adapters" in search. You'll be taken to a page that lists all Macs and whether or not they output sound from their mini-display port. If you don't know what model and year your Mac is, follow these directions- Click Apple icon (upper left of your screen), click "About This Mac", click "More Info". On this screen you'll see the model and year (13 Inch, Mid 2009). If your Mac supports sound through the mini-display port, you're done. Go ahead and order the cable. If not, read further. If your model does not support sound output you can easily get around this by hooking up additional cabling (via the headphone jack or optical port dependent upon model). In either case you should also verify that your TV will accept both sound and audio through discrete sources. Even if your TV doesn't accept separate audio and video sources, if you planned to play sound through a separate receiver, you're okay. If you will not be using a separate audio source for sound and your TV does not support separate inputs for audio and sound (or maybe you're not sure) you may be better off purchasing an alternative device that combines sound and audio via cabling . One such device is the Kanex iAdapt51 for around $35 here at Amazon.
