Mac loses tone signal in the middle of the session

[GDJ]

This is happening to me sometimes. I can play for hours with no problem. In my case, sometimes I hear audio in one channel. Resync always gets me back in. I'm not convinced this is something going on with my gear since I'm using a dedicated boot disk with JK and my Audio interface software. A very vanilla setup. I think this is a JK app issue and yes, possibly for Mac users. The only place I will start looking is in the JK audio BOOSTER. I often tinker around in this section?

Do you guys also make changes in Audio Booster?
