Yep ,Traktor won't recognize z2

so what’s the deal with the z2. Only had it a week, having trouble connecting to my MacBook Pro . It’s like you have to leave it on for 10 minutes to warm up. Looks like it’s going back . I’ve read all the online fixes, which none work. looks like it’s a hardware problem.

 

Looks like we have the same problem. TL;DR you are right, you have to leave it WARM UP for a while, then shut it off and on and the Z2 will work.

I have a video showing the problem on youtube and the description of my contact with NI about this (it's a know issue) and my solution for years:



Since I bought my Kontrol Z2 last year I'm experiencing some issues. First I thought it was a software problem. Then I updated everything and the problem was still there. And now it got worse. My Kontrol Z2 never connected to my Macbook Pro at first try. I always have to turn the Kontrol Z2 on/off several times and restart my Macbook to get it to work. It's really annoying, but I kept doing so, thinking Native Instruments would fix it soon. Then I updated everything as soon as I could and the problem was still there. This by itself is a big problem, mostly now that I'm getting bigger parties to play and things are getting even more professional. I looked around in the forum for a fix, and the only positive answer that I got (from the several posts with the same issue) was a replacement. Here is a video of me trying to get the Kontrol Z2 to connect to my Retina Macbook Pro, with no success. Sometimes I do the same and got it working, sometimes I have to try it for over 10 minutes.

### UPDATE: NATIVE INSTRUMENTS SUPPORT ANSWER ###

Regardind USB connection: after a few e-mails and, when the e-mails didn't solve the problem, I called NI support in the USA (I live in Brazil) and they told me that my Kontrol Z2 has a factory problem in the logic board (or something like that, so a hardware problem) and I'd have to take it to the shop that I bought it (in Hungary), because they don't have international warranty. Basically, I'm stuck with a crappy product and the company doesn't give a s*** about their clients.
