Reply to Recommend a way to setup CDJ HID without owning a pair of CDJ's

Hi
I been DJing with my Traktor S2 for a few months now. I wanna start to DJ in clubs but I don't wanna drag my S2 along with me. I seen other DJ's just use usb wires that go from CDJ's to their Laptop. I currently use a Macbook and my Traktor version is 2.6.

Can anyone recommend a good way to setup my computer so it can easily and glitch free connect to a CDJ 2000 or 900 that is found at most clubs now a days. Is the setup the same whether the CDJ is a 900 or 2000? Or should I use them both incase one club is diff then the other? Any feedback on this is appreciated.

Oh and I looked over a few youtube videos related to this subject.
