Apple just showed off how Notification Center is getting supercharged in OS X Mavericks.
Now in Mavericks, if your machine is sleeping, you’ll see all the Notifications that came in while you were away, all on the lock screen.
Mavericks will also update your apps in the background. And if you get an iMessage or an email, you can reply right from the Notification.
There’s also apparently a new kind of Notification, where apps can send Push Notifications to iOS devices.
Notification Center was notoriously underbaked in Mountain Lion: it’s nice seeing Mavericks getting this right.
