Nexus Mixer

Today I connected the nexus mixer with cdjs 2000 for the first time. Everything worked great I shutdown my mac and restarted. The first thing i checked is the utilty to see if the mixer is reconized and it wasnt at all. I tried 3x shutdown and restart, unplug the mixer and plug and nothing. So as for now for my show i am using the cdjs only as a aggrate card but this another problem with that which i will post in the CDj section
