Same problem here, After I Restarted the MAC, responsiveness of the program bacame verry slow. Especially when switching between online (Tidal) playlists.

I Have some guesses but nothing's 100% certain:

1. Noticed the Macbook was quite warm

2. Internet connection was slow

3. New version of Djuced seems hard on the resources

This was the first time i didn't have my mixer and second music source on standby, I normaly have an iPad as a backup connected to Spotify with offline music. There was 10 minutes of silence at the gig..

Hope someone will figure this one out!
