If you are trying to launch an app on OS X and simply get the error “The application XXX can’t be opened”, the problem could be the actual executable file in the app bundle does not have corresponding permissions.
To fix the issue:
- Open a Terminal and enter into your app bundle. You can just type “cd ”
and then drag the app into the Terminal and then hit the enter.
- cd Contents/MacOS
- chmod +x * or chmod +x <FILENAME> if you know which one is the actual executable.
- sudo !! may be needed if you don’t have permissions to execute step 3.
Now try to launch the app again, and the problem should be solved.
