OS X: When a notification is closed in one computer why it is still present in another computer? Got two computers with the same OS X version, with the same account name and Apple ID, I will call these two equipments A and B.

When a notification pops-out from Calendar app in A the same goes for B, when closed the notification in A, B still shows the notification. The same is true if closed first in B then A keeps showing the notification.

This means that while using A and closing these notifications if you go back to B the same notifications need to be closed again.

Is there a way to make OS X aware that some notifications in B were already viewed and closed in A (sync)?
The only way to remove notifications, at the time of writing, is to take action on the notification. For example, closing a message notification doesn't close it anywhere else, but tapping the message notification and opening Messages does.
