Right, the old ones are better!
So yeah, I got me a new one (with yosemite) and i have problems
Traktor runs OK, but the problem are the controllers...
Normally I use an Xone K2 and a mapping.
At first it all works, but then, after a few hours, problems are starting...
Faders dissapear, decks stop working etc.
So after a while, you don't have any control anymore, it all fails one after another.
The only controller that works is my old NI Z1...
I read that all problems start because of some drivers in the Yosemite-version:
Anyone has done that (i guess not because all of you smart asses have an old MBP )
