Important for Mac users Compatibility with macOS Catalina

With the arrival of macOS Catalina comes stricter signing requirements for all applications as well as the removal of support for 32-bit code. These changes will affect Toon Boom's software, including Harmony 16, Storyboard Pro 6 and prior versions. These applications will not function with macOS Catalina.

To ensure the continued and efficient functionality of Harmony 16, Storyboard Pro 6, and previous versions of our software, we recommend that you remain on your current version of macOS.

Software adjustments have already been incorporated into Harmony 17 which will allow our software to run on macOS Catalina. These same improvements will be an integral part of all future releases, including our upcoming Storyboard Pro 7 (official launch date to be announced soon).

We apologize for this inconvenience. Should you have any questions or concerns, please contact

    If you are using Harmony 16 or Storyboard Pro 6 (or prior versions), you need to revert to the previous version of macOS.

    No. Catalina is a release of macOS, and will not affect users on Linux or Windows.
