Compatibility of Ergonis Software products with macOS / Mac OS X versions

On this page, we give you all the information you need about the compatibility of our products with Apple's latest macOS version. Read through this page to prepare for a painless upgrade to new macOS versions as far as our products PopChar X, Typinator, and KeyCue are concerned.

Important information for early testers of Catalina


The latest versions of our products have been tested successfully on current preview versions of macOS Catalina (10.15). However, some additional care is required during installation:

Typinator only

  • When you double-click the downloaded Typinator disk image, the Finder complains that the disk image "can't be opened because it is from an unidentified developer". The message is incorrect and is caused by a bug in Catalina. You may also see such messages when you try to open disk images from other software companies. As a workaround, control-click or right-click the disk image icon and select "Open". You will then see a similar incorrect warning, but now you can click the "Open" button to mount the disk image.
  • After mounting the disk image, do NOT follow the instructions in the window. Instead of double-clicking the icon, rather perform a manual installation: Make sure Typinator is not running (if it is, quit Typinator), then drag the Typinator icon from the disk image to the Applications folder to install Typinator. Finally, find Typinator in the Applications folder and launch it with a double-click.

PopChar and KeyCue

  • You can mount the disk image on Catalina and install the applications by double-clicking their icons in the disk image window. At the end of the installation, the rotating activity indicator in the bottom right of the window will not stop. Just wait a few seconds, then quit the installer.

All Products

  • Catalina is more restrictive than Mojave with respect to certain permissions. All our products need special permissions to perform their tasks (Typinator: watching keystrokes and inserting expansions; PopChar: inserting characters in documents; KeyCue: finding menu shortcuts and executing menu commands). When you launch the applications the first time, you will be asked to give them permissions to "control your computer", to automate other applications, and to monitor input from the keyboard, mouse or trackpad. You need to activate these permissions to allow the applications to do what they have been designed for.
