12) Provide as much detail of the issue here:

I can perfectly use rekordbox when no Pro DJ Link devices are connected to my Mac. My pair of CDJ-900 and my DJM-900nexus are connected to a D-Link DES-1008A hub which is connected to a D-Link DI-604 hub and then to my Mac through a Belkin Thunderbolt Express Dock (because my MacBook Pro doesn't have ethernet port). I can use rekordbox normally only if I don't have my DJM and CDJs connected. As I connect them and enter the Link mode, in about 30 seconds my Mac simply restarts and an Apple log report shows up.
