Universal Control is one of the most useful Apple features almost nobody turns on. With it, a single keyboard and mouse (or trackpad) control your Mac and your iPad at the same time — you slide your cursor off the edge of your Mac screen and it appears on the iPad. You can even drag and drop files straight across. No cables, no menus, no separate app to install.
This is different from Sidecar, which turns your iPad into a second display that mirrors macOS. With Universal Control, the iPad keeps running iPadOS and its own apps — you're just borrowing one keyboard and mouse to drive both machines. Many people use both together.
What you need first
Universal Control has a specific checklist. If one item is off, the cursor simply won't cross over — so run through all of these:
- macOS Monterey 12.3 or later on the Mac and iPadOS 15.4 or later on the iPad. (It shipped in spring 2022; any Mac on a current macOS is fine.)
- Both devices signed in to the same Apple Account (Apple ID) with two-factor authentication turned on.
- Wi-Fi and Bluetooth on for both. They don't have to be on the same Wi-Fi network, but both radios must be on.
- Handoff enabled: on the Mac, System Settings > General > AirDrop & Handoff; on the iPad, Settings > General > AirPlay & Handoff.
- The devices within about 30 feet (10 m) of each other.
- The iPad is not sharing its cellular connection and the Mac is not sharing its internet connection.
Which Macs and iPads support it
Macs: MacBook and MacBook Pro (2016 and later), MacBook Air (2018 and later), iMac (2017 and later) plus the iMac (5K, 2015), iMac Pro, Mac mini (2018 and later), Mac Studio, and Mac Pro (2019 and later).
iPads: iPad Pro (all models), iPad Air (3rd generation and later), iPad (6th generation and later), and iPad mini (5th generation and later).
Nearly every Mac we sell — from the M1 MacBook Air (from $450) up through the 14-inch MacBook Pro — supports Universal Control out of the box. If you're pairing it with a newer iPad, you're covered.
How to turn it on (there's no on switch — it just works)
This surprises people: there is no big "Enable Universal Control" button to hunt for. Once the checklist above is met, it's on by default. To use it:
- Wake both devices and unlock them. Put the iPad next to your Mac.
- On your Mac, move your cursor to the edge of the screen that faces the iPad, and keep pushing past the edge.
- You'll see a bar appear on the edge of the iPad screen where the cursor is trying to enter. Push through it and the cursor pops onto the iPad.
- Start typing or clicking — your Mac's keyboard and mouse now drive the iPad.
To confirm the toggle exists, go to System Settings > Displays > Advanced… (or the + / Add Display menu) on the Mac — you'll see options like "Allow your pointer and keyboard to move between any nearby Mac or iPad" and "Push through the edge of a display to connect a nearby Mac or iPad." Leave both checked.
Rearranging which side the iPad is on
If the iPad is on your left but macOS thinks it's on your right, the cursor will cross the wrong edge. Open System Settings > Displays, and you'll see your Mac screen and the iPad as boxes. Drag the iPad box to the correct side (and correct height) so it matches where the iPad physically sits. Now the cursor crosses at the right edge.
Dragging files between Mac and iPad
This is the killer feature. Grab a file, image, or block of text on your Mac, drag it to the screen edge, keep dragging onto the iPad, and drop it into a compatible app (Files, Notes, Photos, an email). It copies across using the same engine as AirDrop — no extra steps. It works both directions.
When the cursor won't cross over: fixes in order
- Recheck the Apple Account. Both devices must be on the same Apple Account with two-factor on. A second family account on the iPad is the #1 reason it fails.
- Toggle Handoff off and back on on both devices, then try again.
- Turn Bluetooth and Wi-Fi off and on on both. Both radios must be active even if you never join the same network.
- Turn off Personal Hotspot on the iPhone/iPad and any "Share internet" setting on the Mac.
- Move them closer — within a few feet while testing.
- Lock and unlock both devices, or restart both. A fresh boot clears most stuck states.
- Check the models. An older Intel Mac or a first-gen iPad may not qualify — see the model list above.
If you've been through all seven and it still won't connect, the most common culprit is a mismatched Apple Account or an unsupported model rather than a hardware fault.
Universal Control vs. Sidecar — which do you want?
Universal Control = one keyboard/mouse driving two separate machines (Mac + iPad each running their own apps). Sidecar = your iPad becomes an extra macOS display you can drag Mac windows onto. They aren't rivals — many people leave both on and pick whichever fits the moment: Sidecar for extra Mac screen space, Universal Control for shuffling files between iPadOS and macOS.
Frequently Asked Questions
Do I need to install anything for Universal Control?
No. It's built into macOS Monterey 12.3+ and iPadOS 15.4+. There's no app to download and no real "on" switch — meet the requirements and slide your cursor to the screen edge.
Does Universal Control need Wi-Fi internet?
Both devices need Wi-Fi and Bluetooth turned on, but they don't have to be on the same Wi-Fi network or even online. The link is a direct peer-to-peer connection.
Can I connect two iPads or a second Mac?
Yes — Universal Control supports up to three devices in a chain (for example, one Mac plus two iPads, or two Macs and one iPad), all driven by the one keyboard and mouse.
Will it work on an older Intel MacBook?
Only on the models Apple lists — MacBook/MacBook Pro from 2016 and MacBook Air from 2018 forward, on macOS Monterey 12.3 or later. Very old Intel Macs are excluded. If yours doesn't qualify, an M1 MacBook Air from $450 is the cheapest way onto a Mac that fully supports it — and it's a great Apple clearance pick.
Is Universal Control the same as using my iPad as a second monitor?
No — that's Sidecar. Universal Control keeps the iPad running iPadOS and just shares your keyboard and mouse; Sidecar turns the iPad into a Mac display.
