Total newbie here: I purchased then ran picard on my collection of 60k+ tracks. It ran for over 12 hrs, had already ‘seen’ all my tunes and was at 17k of the AcousticFP. I returned to find no app loaded in Dock, no dialogue showing that it had crashed. I looked for a log, nothing showed.
Perhaps it was a numbers [tracks] problem. Perhaps I shouldn’t have run Acoustic FP at same time??
