I have enjoyed XM on my Mac thanks to MacXM since October. Now with no ads and only $10.00 a month and no load on Internet, XM is a great music bargain. MacXM is fully in sync with develpments that have made Mac the best platform for enjoying music. I have never enjoyed music more with instant channel changes! Outstanding digital quality with direct link to iTunes to buy tracks and to Google for song and artist info. 5.0 quality and support and continued development. Congratulations to Nick Sayer for his work for those in the Mac community who enjoy music in its diverse formats. MeersWorld, Dayton, OH.
