macOS Sierra 10.12.3/Traktor 2.10.0.3 - Track in Deck A hung, new track still hung

First time I've ever seen this happen. See youtube clip to observe the problem.



Song stopped playing in deck A and could not clear or reset deck A by reloading a new track. You can hear deck B still playing. See video for example. Load new track, click play, BPM goes to 0 and the offset is saying -100%? weird. Clicking 'sync' or adjusting the Tempo fader had no effect. Had to reboot / restart Traktor to clear. Had been playing for about an hour.

Wifi may have been on?

Hello, did someone found a solution ? I had this problem 2 days ago on a gig in front of 600 person and I had to stay on 1 track for 2 hours and switch songs without any transition ! Worst experience in my life, I can't get this to happen again so I need a solution...

 

Hey! I'm running exactly the same MBP as you.

I was having some issues similar to this. I have since installed the Supplementary Update for MacOS, reinstalled Traktor with the latest version, and re-imported my Traktor settings. I've not had an issue since.

I've also cleaned my laptop up and deleted a lot of unnecessary files like photos, and other things, and optimised it for DJing. Whilst it's a tad inefficient having a laptop just for DJing, it's been great in terms of performance and reliability.
