Locking your MacBook screen is a simple but important habit. Whether you are stepping away from your desk at home working in a shared office or carrying your laptop around on campus locking your screen helps protect your files and personal information from unauthorised access.
In this guide you will learn how to quickly and effectively lock your MacBook screen using built-in shortcuts settings and system preferences. These methods work across most versions of macOS including the latest ones found on newer MacBook Air and MacBook Pro models.
Why Locking Your MacBook Matters
A locked screen acts as the first line of defence if someone tries to use your MacBook without your permission. It prevents access to emails documents messages and any open apps. Even if you are only away from your screen for a minute it is still worth locking it. It is particularly important if you use your device for work or share a household.
Locking the screen does not shut the computer down or log you out. Everything stays open in the background until you return and unlock it with your password Touch ID or Apple Watch.
Use a Keyboard Shortcut
The quickest way to lock the screen is by using a keyboard shortcut. Press Control + Command + Q and your Mac will immediately return to the lock screen.
This method is fast reliable and works no matter which app or window you are currently using. Once you return you will see the login window ready for your password or biometric ID.
Use the Apple Menu
You can also lock the screen through the Apple menu. Click the Apple logo in the top-left corner of the screen then select Lock Screen. This has the same effect as the keyboard shortcut and is useful if you are not a fan of keyboard commands.
Set Your Mac to Lock Automatically
You can set your MacBook to lock the screen automatically after a period of inactivity. To do this open System Settings then select Lock Screen or Displays depending on your macOS version.
Choose a time interval for when the display turns off then enable Require password after sleep or screen saver begins. You can adjust how soon the password is required from instantly to several minutes. Setting it to immediately gives the highest level of protection.
Use Hot Corners to Lock Quickly
Hot Corners is a feature that lets you assign actions to the corners of your screen. You can set one corner to trigger the screen saver which then locks your screen if password protection is enabled.
To enable this open System Settings go to Desktop & Dock then click Hot Corners. Choose a corner and set it to Start Screen Saver. Once you move your mouse to that corner the screen saver will activate and your screen will lock if the password requirement is turned on.
Locking with Touch Bar or Apple Watch
If you have a MacBook Pro with a Touch Bar you can customise the Control Strip to include a Lock Screen button for even faster access.
If you own an Apple Watch and it is paired with your Mac you can use it to unlock the screen once it is locked. This adds both security and convenience without needing to type your password.
