How to fix Case 1
When the application fails to run, the error "Application can not be opened" appears.
To work around this problem, run the following command line through the chmod terminal (found in / Applications / Utilities /) to make it executable:
chmod + x TheAppName.app/Contents/MacOS/*TheAppName is the application name. To avoid complications, you should change the name of the original application name without "space" and no special characters. For example, the following error occurred: The "Call of Duty 4: Modern Warfare" application can not be opened like the screenshot above . How did you fix it? I first changed the name from "Call of Duty 4: Modern Warfare" to "Call of Duty-4-Modern-Warfare"
chmod + x / Applications /Call-of-Duty-4-Modern-Warfare.app/Contents/MacOS/*chmod+x SomeApp.app/Contents/MacOS/ *
