How to lock your Mac with a passcode

Before you can lock your Mac from your keyboard, you’ll have to set a passcode. This makes it so that you’ll have to use your passcode to unlock your Mac in the future, which also enhances your computer’s overall security.

Here's how to set it up:

1. Click the Apple logo in the top-left corner of the screen and select "System Preferences."

2. Choose "Security and Privacy."

3. Under "General," tick the box next to "Require password after sleep or screen saver begins" (you can change how soon this feature kicks in by selecting an option from the dropdown).

4. You'll be asked to set a password and a security hint. Make sure to come up with a password that you'll remember, but is hard to crack.

How to lock a Mac from your keyboard

Once your Mac has a password enabled, here are two ways to lock it using only your keyboard:

• Press and hold the Control, Shift and Power buttons, or Control + Shift + Eject if your Mac doesn't have a Power button.

When you use this keyboard shortcut, your background processes will continue to function. So, for example, if you have Spotify running, you'll still be able to hear the music or podcast, but your laptop will be locked and you'll have to log back in to use it.

• Press and hold Command, Option and Power, or Command + Option + Eject.

This keyboard shortcut will put your computer to sleep, which locks it and shuts down most background processes.
