Thank you. I finally found a path through Finder and the Media Center shows all the Albums/FLAC files etc. However, I can only play them on my Mac. How do I get the Media Center and the Bluesound Node to communicate. The Node is connected to my Integrated amp. and I have a good wi fi signal from the node but where will the Node be found in the JRiver program? I've spent a lot of time in the knowledge base and now I suspect that this question is too basic (or stupid) to be covered there. Please remember I am new to computer audio and digital music files. It's still bewildering to me. Any suggestions will be helpful since my personal knowledge base is nearly nonexistent. Thanks Bill
