Warning Notifications

Power Manager can perform actions that affect active users. These actions should never be a surprise to the active users. To help ensure users are informed, Power Manager issues a notification well in advanced of the pending event.

When an action that affects users is about to begin, Power Manager displays a second warning notification. This warning notification appears for a brief period before the action performs.

The aim of this second warning notification is to provide the user with a reason for the Mac’s automatically logging out, going to sleep, shutting down, restarting, or other notable action. If the user is not provided with a reason, then the action’s behaviour may be misinterpreted and cause confusion.

Hopefully the combination of notifications will avoid surprises.
