Query: Optical out on IMAC

Couldn't get an answer from Apple, but I will tell you this. I just bought these and if you own an IMAC this will output your sound into a digital format. This is a lot better than using the 3.5mm Stereo Plug / RCA Plug x 2 Y-Cable. I was disappointed at first with the sound quality using the 3.5 mm cable. After looking around a bit, I found this cable and my disappointment quickly faded and turned into joy. You will need an optical input on whatever device you are trying to run your sound through. Enjoy!!
