In the latest versions we upgraded the main framework we use to the latest available version to support our new equation to speech functionality. This will have have no impact for most users.

The only affected users are anyone using MacOS Mojave (2018) or Catalina (2019). The new version of the framework is incompatible with these older versions of MacOS.

If you are affected, please consider updating your copy of MacOS to a later version. Alternatively, we have made a version that runs on Mojave and Catalina available on the Obsolete Versions section of our downloads page (http://www.efofex.com/Downloads.php)
