Ten years on, this hardware and software are still working. Using Yosemite, so I can't speak to El Capitan, but it's a way to listen to (and record) radio without streaming it through your Internet connection. Of course, it might be hard to find the hardware these days, but it's nice that the software still works. Reception is decent (I have a black one with included external antenna) but would probably be better with a better antenna. Software is dated, but still works, which is nice for a discontinued product.
