Put your Mac to sleep or wake it
When you’re not using your Mac, you can save energy by putting it to sleep. When your Mac is in sleep, it’s turned on but consumes much less power. It takes your Mac less time to wake from sleep than it does to start up after being turned off.
Put your Mac to sleep
To put your Mac to sleep, do any of the following:
Choose Apple menu
On a Mac laptop, close the display.
If you have the option on your keyboard, press Option-Command-Media Eject key
.Tip: If your Mac has a Touch Bar, you can add the Sleep button to the Control Strip. Choose Apple menu
in the sidebar. (You may need to scroll down.) Click Touch Bar Settings on the right, click Customize Control Strip, then drag the Sleep button onto the Touch Bar.
Wake your Mac from sleep
To wake your Mac, do any of the following:
Press a key on the keyboard, or click the mouse or trackpad.
On a Mac laptop, open the display.
For security, you can set an option to require a password after waking your Mac. You may be able to unlock your Mac with your Apple Watch or use Touch ID instead of entering your password.
