Case 1: Common error:

  • Can not open "The App" [19659004]
  • and more … (19659006) Case 2: Common error:

    • "Can not open because there are unknown developers. [19659008] "The App" is corrupt and can not be opened. You need to move it to the trash.

    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 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 /*
    chmod+x *
