I have already found this thread, where it is explained how it runs on Sierra:
"to run WebRatio on your Mac OS Sierra please follow these steps:
- Select the WebRatio file stored into WebRatio.app/Contents/MacOS.
- Open the context menu (right click of mouse) and select Make Alias item.
- Move the alias in the "root" folder (at the same level of the WebRatio.app file).
- Double-click on the alias in order to run WebRatio."
I unfortunately cannot find this folder. I have downloaded it and got this file path:
Macintosh HD ▸ User ▸ Admin ▸ Downloads ▸ WebRatio_Platform_University_Student_Edition_7 ▸ WebRatio
When I run the app from this path, I get this warning from above.
I don't know how to get to that path (WebRatio.app/Contents/MacOS).
I have tried to make an Alias of this file but running this, brings the same error.
My Mac runs macOS Mojave 10.14.2
