• Open the UTILITY menu by pressing and holding the INFO / UTILITY button
• Select WLAN SETTING

• Select OFF
• Select YES (to apply changes)
• Power off the AERO, unplug the power supply for 30 seconds, then reconnect it and power the AERO back on
• Open the UTILITY menu by pressing and holding the INFO / UTILITY button
• Select WLAN SETTING
• Select MODE
• Select ACCESS POINT(AP)
• Select YES (to apply changes)
• Press BACK
• Select NETWORK SETTING

On your Mac, open the System Preferences and go to the Network item. Select Wi-Fi and then click the Network Name drop-down list. Find the name of your AERO and select it. Verify that your Status shows as Connected and you have an IP address; it should be one digit higher than the number showing on the screen of your AERO.

Your AERO is now connected. Next, open rekordbox. If you have rekordbox DJ, be sure to switch from PERFORMANCE mode to EXPORT mode.

Press the blue rekordbox button(s) on your AERO, and you should see the LINK button appear at the bottom left of the screen in rekordbox. You need to CLICK that Link button; an icon showing your AERO will appear in the middle of the bottom section (to the right of the LINK button, which will now change to show a Wi-Fi symbol. The screen of your AERO should show rekordbox Control and the name of your rekordbox library. Press the rotary knob to select the library, the display will say Control with Rotary and now you're able to navigate rekordbox and load tracks wirelessly!

Let me know if any of those steps didn't work for you, or if you need further assistance.
