MacBook Pro Magic Keyboard with Touch Bar and Touch ID
The Touch Bar at the top of the Magic Keyboard displays a set of tools that changes based on what you’re doing. Touch ID (the power button) is located on the right side of the Touch Bar. After you set up Touch ID, you can use your fingerprint to unlock MacBook Pro, quickly lock your screen, or make purchases from the App Store, Apple TV app, and Book Store, and on websites using Apple Pay.
You can set up Touch ID during setup, or later in the Touch ID pane of System Preferences. To set keyboard and Touch Bar preferences, open System Preferences, click Keyboard, then click the buttons at the top to see the available options.
Use Touch ID (the power button). Press to turn on your MacBook Pro (or just lift the lid or press any key). When you first start up or restart the computer, you need to log in by typing your password. After setup and initial login, whenever youʼre asked for your password, you can just place your finger lightly on the Touch ID sensor to authenticate.
Press the Touch ID sensor to quickly lock your MacBook Pro screen.
You can also use Touch ID to make secure online purchases with Apple Pay. For more information about Touch ID, see Set up your MacBook Pro. For more information about Apple Pay, see Use Apple Pay on your Mac.
