Art is trying to rip a vinyl album to his computer. He uses a USB turntable and it's not capturing. Leo says that using a USB turntable is the best way to do it, but since Art is using a Mac, it's likely that the software he's using doesn't support Mac. But it also means he may not need that software. Leo advises opening the sound preference pane in the Mac, and see if you can see the turntable. If you do, then you can probably use Garage Band or Amadeus to capture with it. There's also one called Twisted Wave.
Art can't use iTunes? Leo says no, iTunes doesn't support live capture, and you wouldn't want it to.
