We did very recently receive word from another Mac OS / Pro Tools user who starting having issues with Scaler 3 after installing the Pro Tools Speech to Text Engine. This was prompting Pro Tools to crash and want to move Scaler 3 to the unused plugins folder. We are currently looking into this report, but if you do have the Pro Tools Speech to Text Engine installed, you may like try removing it. Scaler 3 was reportedly working without issue in Pro Tools after removing this app.
