Modify Lock Screen Timeout on University-Managed macOS Devices

Objective

On University-managed macOS endpoints, baseline security controls are applied to each device. This baseline affects device settings that trigger the lock screen, which may be noticed by users when their computer locks after a brief period of inactivity, typically around 2 minutes by default. While the managed settings require a Mac's screen saver to activate after 15 minutes of inactivity and require a password upon its activation or when the display turns off after 5 seconds, users can still modify display power settings from their original settings and extend the length of inactivity.

Users

Any user of a University-managed one-to-one macOS device.

Steps

If a Mac is locking and requiring a password after less than 15 minutes of inactivity:

  1. Open System Settings.
  2. Navigate to the Lock Screen settings pane, or search for Turn off display when inactive.
  3. Modify both the Turn display off on battery when inactive and Turn display off on power adapter when inactive settings to a length of time longer than 15 minutes.

You may be asked to enter administrative credentials to make this change. Once these settings are modified, your screen will begin to lock when the screen saver becomes active after 15 minutes of inactivity.
