Is there a keyboard shortcut to lock the screen on macOS 10.14 Mojave like Command + L or something easy without setting up Hot Corners/Spaces etc.

The app Lock Me Now used to work fine till maOS High Sierra, but isn't starting up on macOS Mojave. It is showing this popup as soon as I try to run it:

Is there an app that works on Mojave which helps to customize the lock keyboard shortcut to Command+L? I am used to using Command+L on windows and older Mac OS (using "Lock me now" app).

You can use the built-in keyboard shortcut Control + Command + Q to lock the screen.

The command is also accessible via  → Lock Screen in the Menu bar.


If you are using the windows keyboard, try the below shortcut to lock MAC machine, which is worked for me. Cmd+Ctrl+Q = To lock the Mac machine using windows keyboard.

    This keyboard shortcut also works on Apple keyboards. :)
