-   * Create and display a prompt to enter some text.
-   * @static
-   * @method promptMacOS
-   * @param title The dialog's title.
-   * @param message An optional message that appears above the text
-   *    input.
-   * @param callbackOrButtons This optional argument should
-   *    be either a single-argument function or an array of buttons. If passed
-   *    a function, it will be called with the prompt's value when the user
-   *    taps 'OK'.
-   *
-   *    If passed an array of button configurations, each button should include
-   *    a `text` key, as well as optional `onPress` key (see
-   *    example).
-   * @param type This configures the text input. One of 'plain-text',
-   *    'secure-text' or 'login-password'.
-   * @param defaultInputs This optional argument should be an array of couple
-   *    default value - placeholder for the input fields.
-   * @param modal The alert can be optionally run as an app-modal dialog, instead
-   *    of the default presentation as a sheet.
-   * @param critical This optional argument should be used when it's needed to
-   *    warn the user about severe consequences of an impending event
-   *    (such as deleting a file).
