UA-1X: Drivers for OSX
The UA-1X works with Apple's Core Audio driver. No manufacturer's driver is needed. Once installed, you should select USB AUDIO DRIVER in your System Preferences | Sound for Input and Output. The UA-1X will now act as your sound card, so plug headphones or powered speakers to your UA-1X output. You can play music or sounds through it as well as input audio from the UA-1X to a recording program.
