macOS 10.14.6 Mojave specific issue

If you’re trying to run the current version of Tubulator in macOS 10.14.6 Mojave (or the coming Catalina), you will see the following complaint in a macOS dialog:

“Tubulator” can’t be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information.

The complaint is due to a security hardening in the newest Mojave version (and Catalina). I will fix the required changes in the coming release — the app needs to be “notarized” apart from the code signing it’s already going through..

In the meantime, there’s a workaround.

  1. Right click on the application icon.
  2. Select “Open”
  3. You’ll see the same dialog as before, but this time you have the option to “Open” or “Cancel”. Click “Open”.
  4. The app launches.
