Please read the Update Guide to check the firmware version of your CDJ-850 and how to update the firmware.
For connecting multiple CDJs to a Mac, as well as designating them as audio output device targets for your supporting DJ software, you will first need to set up an aggregated device. This can normally be accomplished by using Audio MIDI Setup, a utility which comes bundled with Mac OS X. We have provided an alternative program called CDJ/XDJ Aggregator, which simplifies this procedure to a single click.
Please also download the instruction manual and read through it before installing the tool.
This tool is not necessary for Windows users because Windows CDJ/XDJ drivers support audio output to multiple devices. Please be sure to install and use the Windows drivers corresponding to your CDJ device.
Verification of OS X Yosemite v10.10 support application software was completed.
