For what it's worth there are a few alternatives for Mac users wanting to make SD cards with the operation system on from "img" files.

I had trouble with a few but ApplePi-Baker seems to work best.

I did also look at Volumio as a high end audio dedicated OS. I loved the idea that it focussed on audio and didn't mess around with any wasted resources on video. However, it was pretty unstable for me (drop outs and pops). RaspBMC has worked flawlessly so far.
