These applications are fully compatible with macOS Catalina.
With Avid releasing Pro Tools 2019.12 and qualified it to run with macOS Catalina (10.15.3) we tested our 64-bit applications on a system with these installed. All functions of our 64-bit applications performed as expected including how they interact with Pro Tools. See the Pro Tools File Type Limitations on macOS Catalina page and the Avid Pro Tools Operating System Compatibility Chart for more Avid compatibility information.
Note: To re-conform Pro Tools sessions with PT v2020.3+ when the session has a frame rate of 29.97 FPS, EdiLoad v4+ is required to work around a change in these versions of Pro Tools.
We will update this blog post as we release updates of our applications that are fully compatible with macOS Catalina, and include info on Pro Tools compatibility.
Application installers can be downloaded from our download page.
