I’ve been experiencing some issues since the latest updates of macOS and Traktor. I’m using Traktor Pro 4 (version 4.0.5.0 7) with a Pioneer DJM-A9 and two XDJ-700s. Everything was working fine until the updates. I’ve noticed some sound glitches that sometimes force me to restart Traktor. Also, the waveform occasionally becomes blurry when I load a track onto a deck. The problem gets even worse when I’m playing with another DJ who is using a USB. Which is the best macOS to use?
