The wireless Magic Keyboard with Touch ID and the Magic Keyboard with Touch ID and Numeric Keypad (shown below) have built-in features that make it easy to enter emoji, switch keyboard languages, lock your Macmini, and perform many system functions with the touch of a key. You can also use a fingerprint to sign in and make purchases using Apple Pay.
To connect your Magic Keyboard with Touch ID to your Macmini, see Connect accessories to your Macmini.
Turn the keyboard on or off. Slide the on/off switch on the back edge of the keyboard to turn it on (so green is visible) or off. If your keyboard isn’t recognized by your Mac, connect it to your Mac with a USB-C Charge Cable or USB-C to Lightning cable to pair it, then disconnect the cable to use it wirelessly. Use the same cable to charge your keyboard.
Lock your Macmini. Quickly press Touch ID. To unlock your Macmini, lightly touch Touch ID, or press any key and type your password.
Set up Touch ID. You can use your fingerprint to unlock your Mac and make purchases from the AppStore, AppleTV app, and AppleBooks, and on websites using ApplePay. If you don’t set up Touch ID when you set up your Mac, you can do it later in the Touch ID & Password settings in System Settings. For more information about Touch ID, see Set up your Macmini. For information about ApplePay, see Use Wallet and Apple Pay.
Use Touch ID. Place your finger lightly on Touch ID. When you first start up or restart your Mac, you need to type your password to log in to your Macmini. After that, whenever you’re asked for your password to unlock the screen or make purchases, you can use Touch ID. If you set up fast user switching with your Macmini, you can also use your fingerprint to switch from another user’s account to your own. For more information, see Use Touch ID on Mac.
Set keyboard settings. To specify options for your keyboard and the Function (Fn)/Globe key , open System Settings, click Keyboard in the sidebar, and choose options to change your keyboard or input source, show emoji and symbols, start dictation, or define functions.
Use your keyboard to right-click. Use the new Contextual Menu key to open a shortcut menu with your keyboard. See Right-click on Mac.
Use emoji or switch keyboard languages. Press to switch to a different keyboard. Press repeatedly to cycle through emoji options or other languages you specify in Keyboard settings, or press twice quickly to start dictation (if you set that preference). On Magic Keyboard with Touch ID, the key is in the bottom-left corner.
Use function keys. The function keys on the top row provide shortcuts for these common system functions:
Brightness (F1, F2): Press or to decrease or increase the brightness of the screen.
MissionControl (F3): Press to view what’s running on your Mac, including all your spaces and open windows.
Spotlight Search (F4): Press to open Spotlight and search for something on your Mac.
Dictation/Siri (F5): Press to activate dictation—you can dictate text wherever you can type (for example, in Messages, Mail, Pages, and other apps). Press and hold to activate Siri, then immediately speak your request.
Do Not Disturb (F6): Press to turn Do Not Disturb on or off. When Do Not Disturb is on, you won’t see or hear notifications on your Mac, but you can view them in Notification Center.
Media (F7, F8, F9): Press to rewind, to play or pause, or to fast-forward a song, movie, or slideshow.
Mute (F10): Press to mute the sound.
Volume (F11, F12): Press or to decrease or increase the sound volume.
Use alternate functions. Function keys may perform actions for specific apps or may have alternative functions—for example, the F11 key can also hide all open windows and show the desktop. To trigger the alternative function associated with the key, press and hold the Function (Fn)/Globe key while you press a function key.
Use keyboard shortcuts. You can press two or more keys at the same time to quickly do things on your Mac that you’d normally do with a trackpad, mouse, or other device. For example, press Command-C to copy selected text, then click where you want to paste the text and press Command-V.
