Most people do not know their Mac can be an AirPlay receiver. Turn it on and you can put an iPhone, an iPad, or another Mac right on its screen, with no cables and no extra apps. It has been built into macOS since Monterey, and you can even use that second Mac as a real extended display.
It is genuinely useful, but it is not a replacement for a wired monitor. There are hardware requirements, and there are two tradeoffs that decide whether this works for what you actually want to do. Here is the full setup, and the honest limits.
A quiet, cable-free way to throw an iPhone, iPad, or second Mac onto another Mac's screen. Great for casual mirroring and presentations, not for pixel-perfect work.
- No cables and no apps, built into macOS since Monterey
- Mirror, share one window, or extend as a real second display
- Route audio to either Mac, and control both with one keyboard and mouse
- Capped at 1080p, so text looks softer than native
- Runs over Wi-Fi, so there is some lag
- Older Macs are not supported
What AirPlay to Mac actually does
AirPlay itself is old news. You have been able to send music to speakers or throw your phone onto an Apple TV for years. The newer part is that a Mac can now be the receiver. So whether you want to mirror an iPhone, an iPad, or another MacBook, you can drop any of them onto a Mac’s screen.
The reason it is worth setting up: no cables, no third-party software, and on another Mac you can use it as a full extended display rather than a simple mirror.
Which Macs actually support it
Before you touch any settings, check the hardware, because this is not available on every Mac. As a rule it works on most Macs from 2018 or newer, but the cutoff is different by model. The receiving Mac also needs macOS Monterey or newer, and both devices have to be on the same Wi-Fi network.
If you are on an iMac older than 2019, you cannot use it as an AirPlay receiver.
| Mac model | Minimum year to receive AirPlay |
|---|---|
| MacBook, MacBook Air, MacBook Pro | 2018 or newer |
| iMac | 2019 or newer |
| Mac mini | 2020 or newer |
| Mac Pro | 2019 or newer |
| Mac Studio | Any model |
Turning on AirPlay Receiver
Start on the Mac you want to be the receiver. Open System Settings, click General, go to AirDrop & Handoff, then scroll down to the AirPlay section and make sure AirPlay Receiver is checked.
Then decide who is allowed to connect:
- Current User locks it to devices signed in to the same Apple ID.
- Anyone on the same network allows anyone already on your Wi-Fi.
- Everyone opens it up the widest. At home, stick with same-network.
You can also require a password. A one-time password stays the same each time, or you can have a code pop up on the receiving Mac’s screen, which means someone has to physically see that screen to connect.
Connecting from an iPhone, iPad, or another Mac
From an iPhone or iPad, swipe down from the top right to open Control Center, tap Screen Mirroring, and the receiving Mac shows up in the list.
From another Mac, click Control Center in the top right, go to the Screen Mirroring section, and pick the Mac you want. Once it connects you will either get a prompt or you can click the purple AirPlay icon in the menu bar to open the options.
Mirror, share one window, or extend
Click Choose Content and you get three ways to use the second screen:
- Entire screen mirrors everything on the display.
- Window or app sends just one specific application.
- Extended display treats the second computer as another monitor, so you get two Mac screens out of one.
Extended display is the one that turns a spare Mac into real extra desk space instead of a duplicate.
Fixing the display arrangement
Depending on where each machine physically sits, the direction you scroll between screens can be backwards. In my setup the second computer is on the left of the MacBook Air, but I had to scroll right to reach it.
To fix it, open System Settings, go to Displays, and click Arrange. Drag the second display to the correct side and the cursor will slide across the way you expect.
The two tradeoffs to know first
There are two real costs to this setup, and they are the whole reason it is not a full monitor replacement.
It caps at 1080p. Even if the receiver is one of Apple’s 5K iMacs, AirPlay compresses everything down to 1080p, so text and fine detail look softer than they would natively.
It runs over Wi-Fi, so there is lag. This is not instant. Typing and quick interactions on the mirrored screen feel behind, and a crowded network or weak signal makes both problems worse. If you have the option, running the two Macs hardwired to the network always feels snappier than Wi-Fi. None of this makes it useless, it just means this is best for casual mirroring or presentations, not for anything where pixel-perfect detail or instant response matters.
A few extras worth knowing
Once you are connected, a few smaller features make this a lot more usable:
- Send the audio where you want. In Control Center under Sound, choose whether the audio plays through the Mac you are on or the second computer. That is handy if the second machine is wired to speakers or a sound system.
- Watch video on the side. Push a full-screen video window onto the second screen and keep working on your main display.
- One keyboard and mouse across both. There is a related feature called Continuity. In Control Center click Display, then Link Keyboard and Mouse to, and pick the other Mac. The difference: with Continuity each Mac stays its own computer, so you cannot drag a window across, you open apps on each machine separately. AirPlay’s extended display is the better pick when you actually want to move windows between screens.
Is it worth using?
AirPlay to Mac is one of those quiet Apple features most people do not know exists. If your hardware supports it, it is a genuinely useful, cable-free way to get an iPhone, iPad, or another Mac onto a second screen in seconds.
Just go in knowing the limits. The 1080p cap and the Wi-Fi lag mean this shines for casual mirroring, watching something on the side, and presentations, and it struggles for detailed or fast work. Set expectations there and it is a great free trick. Push it as your main monitor and the tradeoffs will show.
