i have a home theatre system that I usually hook up to my PC that requires a SPDIF Coaxial Input from a computer.
Does the Macbook or MBP have a SPDIF Coaxial? If so is there like an adapter or something that will allow the macbook for the SPDIF Digital Coaxial Audio Input?
how exactly does that cable work? Where do I put it in? Where exactly do I put it in from the home theatre machine's coaxial input, the coaxial cable itself (which end?) or on my computer?
The gold tip end goes in the audio input port for your MacBook Pro if you are recording digital audio, and audio output (headphone) port for your MacBook Pro if you are playing digital audio.
You should be able to get a Toslink cable that hooks up to your SPDIF port
