Work with multiple devices
Your Mac works with your other Apple devices. Continuity lets you unlock powerful capabilities when you use Mac, iPad, iPhone, or Apple Watch together.
Before you begin. Make sure your Mac mini and iOS or iPadOS device have Wi-Fi and Bluetooth turned on and are signed in with the same Apple ID.
Use your iPhone with your Mac
Add iPhone widgets to your desktop. Put your iPhone widgets directly on your Mac desktop. Use the Widget Gallery to select iPhone widgets for your Mac or drop widgets from Notification Center onto your desktop. To open the Widget Gallery, Control-click the desktop, then select Edit Widgets.
Use your iPhone as a webcam. Continuity Camera on your Mac lets you use your iPhone as an additional camera for your Mac. You can use your iPhone camera to make video calls. After you set up Continuity Camera, your Mac can automatically switch to using iPhone as a camera when it is in range. You can also use a wired connection if you prefer. See Choose an external camera and Use your iPhone as a webcam in the macOS User Guide.
Note: To use Continuity Camera as a webcam requires an iPhone XR or newer. To use Continuity Camera to share photos, you need an iPhone or iPod touch with iOS 12 (or later) or an iPad with iPadOS 13.1 (or later) installed.
Use your iPhone microphone. With Countinuity Camera, you can use your iPhone as a microphone for your Mac. Use the Video menu in FaceTime to select your iPhone during a call, or use app settings to switch to your iPhone’s microphone during video calls. You can also use Audio settings in System Settings to select your iPhone as your system microphone.
Use iPhone apps on Mac. Many of your favorite iPhone and iPad apps work on your Mac. See Use iPhone and iPad apps on Mac with Apple silicon in the macOS User Guide.
Phone calls and text messages on Mac. With a Wi-Fi connection, you can take calls—and make them—right from your Mac mini. You can also receive and send text messages.
On your iPhone, go to Settings > Phone and enable Wi-Fi calling. Then, on your Mac, open FaceTime. Go to Settings, choose General, then click “Calls from iPhone.” See Set up your iPhone and Mac for phone calls in the FaceTime User Guide.
Use your iPhone as a Hotspot. Lost your Wi-Fi connection? With Instant Hotspot, you can use the Personal Hotspot on your iPhone or iPad to connect your Mac mini to the internet instantly—no password required. See Use an iPhone or iPad to connect to the Internet in the macOS User Guide.
Click the Wi-Fi status icon 
in the menu bar, then click 
next to your iPhone or iPad in the list (if you don’t see the list, click Other Networks). The Wi-Fi icon in the toolbar changes to . You don’t need to do anything on your device— Mac mini connects automatically. When you’re not using the hotspot, your Mac mini disconnects to save battery life.
Tip: If you’re asked for a password, make sure your devices are set up correctly. See the Apple Support article Use Instant Hotspot to connect to your Personal Hotspot without entering a password.
Use your iPad with your Mac
Get even more out of Mac mini by using it with your iPad. Sidecar lets you use your iPad as a second display for your Mac — giving you extra space to spread your work out and draw in your favorite Mac apps with Apple Pencil. With Universal Control, you can also control your iPad with your Mac keyboard and mouse or trackpad, making it easy to move content between iPadOS and macOS. Plus you can quickly markup screenshots, PDFs, and more.
Use your iPad as a second display for your Mac. With Sidecar, you can use your iPad wirelessly within 32 feet (ten meters) of your Mac, or you can connect your iPad to your Mac with a cable to keep it charged. To set up your iPad as a second display, go to Apple menu 
> System Settings, click Displays, then choose your iPad from the Add Display pop-up menu. Later, you can connect to your iPad in the Display section of Control Center 
. To disconnect your iPad from your Mac, click the Sidecar button 
in Control Center. You can also tap 
in the sidebar of your iPad.
Note: You can use Sidecar with iPad models that support Apple Pencil and run iPadOS 13.1 (or later). For more information, see the Apple Support article Apple Pencil compatibility.
Set Sidecar settings. Open System Settings, click Displays, then click the name of your iPad. You can then specify Sidecar settings for your iPad, such as whether it is the main display or mirrors your Mac, whether it shows the sidebar and where it is located, and if you can double-tap with Apple Pencil to access tools.
Note: If you haven’t set up your iPad, you don’t see these options in Display settings.
Use Apple Pencil. Precisely draw and create in your favorite pro apps. Just drag the window from your Mac to your iPad and start using Apple Pencil. Or use Apple Pencil to mark up PDFs, screenshots, and images. To learn more, see See Insert sketches with Continuity Sketch in the macOS User Guide and the Apple Support article Use Markup on your iPhone, iPad, or iPod touch.
Note: Pressure and tilt for Apple Pencil only work in apps with advanced stylus support.
Extend or mirror your desktop. When you connect your iPad, it automatically becomes an extension of your Mac desktop, so you can drag your apps and documents between your Mac and iPad. To show your Mac screen on both devices (mirror the display), move your mouse over the Sidecar button in Control Center, click the right arrow that appears above the button, then select Mirror Built-in Retina Display. To extend your desktop again, open the menu and choose Use As Separate Display.
Take advantage of sidebar shortcuts. Use the sidebar on your iPad to quickly reach commonly used buttons and controls. Tap the buttons to undo actions, use keyboard shortcuts, and display or hide the menu bar, Dock, and keyboard.
Tip: For quick access to the Sidecar options, you can set Display settings 
to always appear in the menu bar. Go to System Settings > Control Center, then use the pop-up menu next to Displays to select whether to show the Displays icon in the menu bar all the time or only when active. When Sidecar is on and your iPad is connected, the Display icon in the menu bar changes to .
Use a single keyboard and mouse or trackpad to control multiple devices. With Universal Control, you can use a single keyboard and a mouse or trackpad to control multiple devices. When you move the pointer to the edge of your Mac mini screen, the pointer moves to your iPad or another Mac, so you can work across up to three devices.
Note: To use Universal Control, you must have macOS version 12.3 or later on your Mac and iPadOS 15.4 or later on your iPad.
Check your connections. Universal Control on your Mac uses Bluetooth to detect another device and Wi-Fi to connect it. Make sure each device has Bluetooth turned on and is connected to Wi-Fi. Also make sure Handoff is turned on in the General settings on your Mac mini and in Settings > General > AirPlay & Handoff on your iPad. You must also be signed in with the same Apple ID on both devices, and have two-factor authentication turned on. When these settings are correct, you can use Control Center to connect your devices. On your Mac, click Control Center in the menu bar, click Screen Mirroring, then choose a device below Link Keyboard and Mouse.
Move between screens. On your Mac, use your mouse or trackpad to move the pointer to the right or left edge of the screen closest to your iPad, pause, then move the pointer slightly past the edge of the screen. When a border appears at the edge of the iPad screen, continue moving the pointer to the iPad screen.
Drag and drop. Select the text, image, or other object you want to move, then drag it to where you want it on your other device. For example, you can drag a sketch you drew with Apple Pencil from your iPad to the Keynote app on your Mac mini. You can also copy something on one device and paste it on the other.
Share a keyboard. When the pointer is in a document or anywhere that you can enter text and the insertion point is blinking, begin typing.
