Don't know whether this is a Rekordbox/DDJ/Laptop error so i will post in both threads. Basically i have the DDj RZ & DDJ RX. I recently bought a new laptop which is the Macbook Pro El Capitan 10.11.5. While im mixing generally or recording aswell, the sound completely cuts off, so you cannot hear anything. my rekordbox is still running and doesnt freeze along with the controller but there is literally no sound. when i playback the recording it will be playing fine then when the sound cuts out the recording will just loop like if a CD Skips. I need this sorted as i am dj'ing my event on friday and have a festival next week and can't have the sound cutting out as i will look like a right t**t. I have installed the firmware on the RZ, updated the drivers, uninstalled and reinstalled, updated my lapotop but still no luck. Both my Decks work fine on my windows 10 PC.
