MacXM is working great for me since I installed two days ago. I bought the $49 antenna and receiver from the XM site and installed the MaxMX software-- and importantly the separate driver you can get from the link on the MacXM website-- and I am enjoying the many channels of high quality music. Thanks to Nick for making this great music resource available to the Mac community. Highly recommended to all. At $10 a month, the XM service is a bargain and MacXM gets a 4 plus from me with a sure 5 as development continues.
