Execute App (Apps Authorization Revoked) Hello there I am trying to start an app (downloaded from the Internet) on macOS Mojave 10.14.5 though when I double click I get the following pop up message:


  “Ascabart” can’t be opened. You should move it to the Trash.


There is also a question mark button that gives me more info:


  The app’s authorisation has been revoked
  
  There may be a problem with this app. Although the app was signed by
  an identified developer, the certificate for the app has been revoked
  and it cannot be opened.
  
  Check with the Mac App Store or the software developer to see whether
  there is an updated version of this app.


Now I still want to execute the app since I myself know I can trust it. How can I do so?

In my Security System Preferences I already have:


  Allow Apps downloaded from anywhere


selected

If there is no easy way can I modify the certificate or app profile?

Thanks a lot!
Something tells me you have upgraded to Catalina and have run into Apple's heightened security around apps.

As is often the case, Apple has hidden how to get around this in plain sight, in a completely non-discoverable way:

Right or Control click on the App and select Open from that contextual menu. the resultant dialog box will then allow you to open the app.
