Using a Mac alongside an iPad offers incredible versatility for productivity, creative illustration, and reference reading. However, constantly switching between an external mouse or trackpad for your computer and tapping the iPad touchscreen disrupts your workflow. While Sidecar turns your iPad into an extended secondary display for macOS, Universal Control provides a fundamentally different and superior multi-device experience: it lets you control both independent operating systems simultaneously using a single Mac mouse, trackpad, and keyboard.
Universal Control vs Sidecar: Understanding the Difference
Before configuring settings, it is vital to distinguish between Apple’s two multi-device features:
- Sidecar: Mirrors or extends your Mac desktop onto the iPad screen. The iPad ceases running iPadOS apps and behaves purely as an external monitor for macOS windows.
- Universal Control: Both devices continue running their respective operating systems independently. Your Mac pointer glides across the edge of your monitor directly into iPadOS, allowing you to launch iPad apps, type into iPad documents, and drag files between macOS and iPadOS seamlessly.
Hardware and Account Prerequisites
Universal Control requires strict hardware and software compatibility across both Apple devices:
- macOS Monterey 12.4 or Later: Compatible with MacBook Pro (2016+), MacBook Air (2018+), iMac (2017+), Mac mini (2018+), and Mac Studio.
- iPadOS 15.4 or Later: Compatible with iPad Pro (all models), iPad Air (3rd gen+), iPad (6th gen+), and iPad mini (5th gen+).
- Same Apple ID: Both devices must be signed in to the identical Apple ID using two-factor authentication.
- Connectivity: Wi-Fi, Bluetooth, and Handoff must be switched on on both devices, and they must remain within 10 metres (30 feet) of each other. Cellular connection sharing must be switched off.
Step 1: Enabling Universal Control on Mac
To enable peripheral sharing on macOS:
- Open the Apple menu () and click System Settings (or System Preferences on older versions).
- Click on Displays in the left sidebar.
- Click the Advanced… button at the bottom of the Displays window.
- Toggle on all three Universal Control options:
- Allow your pointer and keyboard to move between any nearby Mac or iPad.
- Push through the edge of a display to connect a nearby Mac or iPad.
- Automatically reconnect to any nearby Mac or iPad.
- Click Done.
Step 2: Enabling Handoff and Cursor Sharing on iPad
Next, ensure your iPad is configured to accept inputs from external Apple hardware:
- Open Settings on your iPad.
- Tap on General.
- Select AirPlay & Handoff.
- Toggle on Cursor and Keyboard (also ensure Handoff is enabled).
Step 3: Arranging Display Edges for Intuitive Navigation
To ensure your Mac cursor crosses over naturally based on where your iPad physically sits on your desk:
- On your Mac, return to System Settings > Displays.
- In the display arrangement preview, you will see your Mac monitor and your iPad screen.
- Drag the iPad display thumbnail to match its physical position (e.g. to the left, right, or beneath your Mac display).
- Now, push your mouse cursor firmly past the chosen edge of your Mac screen. A subtle grey bar will pulse on the iPad edge, and your cursor will emerge on iPadOS as a circular touch pointer.
Practical Universal Control Workflows
Once connected, you can harness powerful cross-platform interactions:
- Unified Keyboard Typing: Wherever your cursor currently rests is where keystrokes are directed. Click into an iPad Notes document or Procreate search bar, and your Mac mechanical keyboard types directly into iPadOS.
- Cross-Platform Drag and Drop: Click and hold an image or PDF in Mac Finder, drag it off the edge of your screen onto your iPad, and release it directly into the iPad Files app or an active email draft.
- Trackpad Gestures: Two-finger scrolling, pinch-to-zoom, and three-finger swipe-up for the iPad App Switcher function seamlessly using your Mac Magic Trackpad.
Universal Control vs Sidecar Comparison
| Feature | Universal Control | Sidecar |
|---|---|---|
| Operating Environment | Mac and iPad run native OS independently | iPad becomes a secondary Mac display |
| App Execution | Runs native iPadOS apps | Runs macOS windows only |
| Apple Pencil Support | Operates normally inside iPad apps | Works as stylus input for Mac applications |
| File Transfer | Direct drag-and-drop between OS filesystems | N/A (files remain in macOS filesystem) |
Troubleshooting Disconnected or Unresponsive Pointers
If pushing your cursor against the display edge fails to connect to your iPad:
- Toggle Bluetooth and Wi-Fi: Toggle Wi-Fi and Bluetooth off and on across both devices to refresh Apple Continuity handshakes.
- Check Distance and Interference: Keep devices within 1 metre of each other on your desk to prevent 2.4GHz Wi-Fi interference from dropping the peer-to-peer connection.
- Force Display Recognition: In Mac System Settings > Displays, click the + (Add Display) dropdown at the top right and manually select your iPad under Link Keyboard and Mouse.
Universal Control bridges the gap between macOS and iPadOS, letting you leverage the tactile precision of the Apple Pencil alongside the typing speed of your Mac desktop keyboard.
