Thanks for recommendation. I updated Macbook M3max to Sequoia 15 - Seems that the version 4.1 from Traktor Pro 4 DJ is working. But I have the following problem: I did a click "too fast" , means I did not allow Traktor to use my media library etc. when it asked me during the opening process on Sequoia. Now Traktor shows me my Playlists and all tracks of the track collection but is not able to play the tracks. I cannot find the button to solve this "problem". How can I allow Traktor now to access my tracks etc. Thank you for helping.
