  4. Click on the Aggregate Device name once to rename it, you will need to change it to the exact name and spelling of your device. In this example, we are using the MixTrack Platinum. If you are unsure of the exact device name, you should see it listed already on the left-hand side as an available USB audio device.

  6. Launch Serato DJ, make sure computer volume is turned up. You will also need to make sure the master volume of the DJ controller in use is turned up. You will now be able to play using the Mac computer's built-in output, instead of having to connect speakers to the RCA outputs.
