Any way to prevent a notification from appearing in Notification Center? I'm writing a simple AppleScript to create periodic notifications, but I don't want those notifications to accumulate in Notification Center. Is there any way to keep them from appearing there, or to expire them, or to delete them?
Open the notification centre
Press the little cog icon on the bottom right
Find your application in the list
Select your application and unselect "Show in notification center".
