OS 10.13.6 + all updates
Quit CB 10.5.0, beachballs forever. you must force quit the app. ALWAYS save first before quitting.
interesting note - VST instruments are still active and external MIDI keys will play the instrument even though the apps is beach balled.
no high CPU activity , 133% on 12/24 core machine. Ram usage is 1.3 gb which is fine. App is simply stalled out in a loop.
