Answer 1

It works, but you must

1. Code sign your application;
2. Set alert string value for NSUserNotificationAlertStyle key in your app info.plist file;
3. Make sure they are not turned off in Notifications tab of System Preferences.

If you already experiment with notifications it will be better to perform it from scratch. Here how you can remove app from User Notification Center.
