I can see the app in die activity manager only a few seconds. After then it disappears. Of course I pushed the app in die app folder. When I try to start the app out of the DMG, I got the "damaged" message. But starting the app out of die application folder, it does nothing.
I gave it a new try now. I deleted the app, pushed it a new time in die app folder und it started with the "damaged" app. Then I run the script and after completing the script I started the app again. It's the same behavior as mentioned above.
