In today's world, quickly securing your computer is essential. Whether you're stepping away from your desk at the office or from your MacBook at a coffee shop, knowing how to lock your screen instantly is a critical privacy habit.

Many users search for a dedicated hotkey to lock Mac, expecting a single key like on Windows. While macOS handles this a bit differently, it's just as powerful and customizable.

This guide will cover the essential keyboard shortcut to lock Mac screen and how to create your own.

What's the keyboard shortcut to lock Mac screen?

Contrary to popular belief, macOS does not have a single-key "Lock" shortcut enabled by default. However, there are two primary keyboard combinations that achieve the same result: instantly locking your screen and requiring your password to regain access.

The Standard Shortcut: Control + Command + Q

Pressing Control + Command + Q will immediately lock your screen. This shortcut triggers the same function as selecting "Lock Screen" from the Apple Menu () in the top-left corner of your menu bar. Your screen will fade to a login window, and all your applications and documents will remain open and untouched in the background.

The "Log Out" Confusion: Shift + Command + Q

Be careful not to use Shift + Command + Q. This shortcut will prompt you to log out of your user account, which will close all your running applications. Unless you want to save everything and fully sign out, stick with Control + Command + Q.

Mac Lock Screen PC Keyboard Shortcut / Windows Keyboard

If you use a non-Apple keyboard (a PC or Windows keyboard) with your Mac, the shortcuts remain the same. The Control, Command (which is the Windows key), and Q keys are in standard positions, so Ctrl + Windows Key + Q will perform the lock screen function perfectly. This is your true Mac lock screen shortcut Windows keyboard solution.
