State of the art? LOL! Anyway, you should make sure you have the latest Windows Media Player for the MAC installed on that maching, go here to download:

It should work with every CJ broadcast except those that use the ShoutCast server. When those are streaming, you might want to try and see if you can use iTunes to listen to that broadcast.
I'm not sure what you're referring to when you say "tabs." The windows media player doesn't have tabs and that's what you should be using to tune in.
