How to lock your screen on a Mac

Board policy 2022 recommends that staff with confidential files use a screen locker to help protect the privacy of information on the computer. Here’s how to set it up on your Mac:
Open System Preferences (from the Apple menu, or the Dock).


Click on Desktop & Screen Saver, then click the “Screen Saver” tab if it’s not already selected.

Pick any screen saver (you can preview them by clicking them once). Set a time for it to start
(10 minutes is usually good.)

Click on Show All in the Tool bar, to get back to the System Preferences.
Click on Security in the top row of System Preferences

Check the Box for “Require a password to wake this computer from sleep or screen saver.”
Optionally: you can make it so that the screen saver starts when you “park” your mouse in one corner of the screen. The lower left corner works well for this.
In system Preferences, click Desktop & Screen Saver

Click Hot Corners in the lower Left

Choose the drop down menu in the lower left, and select “Start Screen Saver”
Click OK to close
When you move your mouse and leave it in the lower left corner of your screen, the screen saver will start, and lock your screen.
