YES, and it woks fine, or should I say: it works with the same problems as it did with ML?!?
because the problem togehter with iTunes is still the same. So when you run iTunes at the same time just to hear music or to do playalongs with a loaded logic pro x (or logic pro 9) you will get all approx 10 minutes a very strange audio-behavior. It sounds for a couple of minutes that the audio doubles and repeads very loud. I spend some days with testing and did a complete new installation with ML and Maverics and only Logic Pro X (or 9) togehter with the apple support, but it is still there. Did anyone of you get the same problem? So just a clean installation of ML or Maverics with Logic Pro (9 or X doesn't matter) Load a small project in Logic and run in another window itunes. After a while, (1. time it takes about 20 minutes) you will got a very strange audio problem and it does not matter which kind of audio it is. I tried to use VLC instead, but it produces exactly the same behavior.
Would be great if someone could test this on his iMAC
