How do I disable all notifications from the lock screen on Mavericks? I want to receive notifications while using my computer, but don’t want anything to show publicly when I lock my screen and walk away.
I’ve already gone in to the Notification System Preferences and disabled the “show notification on lock screen” option for every app. But when I install a new app I have to remember to go in there and change that settings, and there are other things built-in to Mavericks that show notifications on the lock screen anyway without any apparent option to hide: the App Store notifying about new updates, a system warning when a USB key is unplugged without ejecting it first, and so on.
How do I globally disable all notifications on the lock screen?
