Since this is the primary question today and after a quarter million views, decided it was time for a new & easier thread.
This will be just a down and dirty:
"You want the audio and video on your TV, you have 'x' Mac, then you need 'y' cable(s)".
For those that don't care about the why and just want to know what to buy.
Specific adapter/cable types are provided for all notebook Intel Macs (beginning in 2006 thru 2013).
For PPC Macs, you can still have a read through the original thread - here
For all troubleshooting issues,
more extensive research, or
connecting your Mac to something other than HDMI;
you should read through the first 4 posts in the original thread - here
Find your Mac in one of the lists below and read through that particular post.
Don't know what Mac you have:
Click on the Apple - left side of the menu bar - About this Mac
Or head to everymac.com
to find your specific model.
Once you've found your Mac in the lists and know what cable(s) you need, go on down and also read post # 6.
