NSDistributedNotificationCenter is a way to send a notification out across the
system. Only processes that are listening for the notification will receive it
and have a chance to do something with it. It’s like yelling out in a crowded
room to tell a single person something. Everyone will hear your message, but
only one will be listening. Make sense?

But what it really sounds like you want to use XPC (Cross Process
Communication) for a more targeted messaging (possibly with payloads) between
your app and menuling.
