Reply to Recording with traktor/audio4

Hi!
I made a couple of search about it but i found nothing who can help me.
So, i want to know if its possiible to record with my audio4.
I'm running 2 cdj 200, an old numark dxm 09, tsp 2.6.1 and a macbook pro.
On an old setup i was using the Line In of a PC, but now on my macbook pro, there's no line in.. So i really dont know what to do.. Someone can help me?
Thanks a lot

Carl
