How to lock your Mac's screen

On Windows, it’s simple. WinKey + L is all you need to prevent unscrupulous people from taking over your computer when you’re away.

On a Mac, however, the lock feature is hidden within a utility called Keychain Access. Besides being able to lock your screen, Keychain also stores passwords that you use on the computer and online. To enable screen locking:

  1. Navigate to Keychain Access (Cmd+Space and typing in Keychain should do the trick)
  2. Go to Preferences,
  3. In the General Tab, check “Show keychain status in menu bar”. When that is done you should see a lock symbol in your menu bar, like this:
  4. Click the lock icon, then click Lock Screen. That’s all!
