How to mirror your Mac to your iPhone
Every guide for this search is about the opposite direction. You want your Mac on your phone, and Apple has no button for it.
Short answer: Apple has no built-in way to mirror a Mac to an iPhone: iPhone Mirroring shows your iPhone on your Mac, and AirPlay sends your Mac to a TV or another Mac, not a phone. To see your Mac screen on your iPhone, turn on macOS Screen Sharing and connect with a VNC viewer app, or use MightyMouse, which shows the live screen in Safari after a QR scan and lets you drive the Mac too.
Search for this and most of what comes back is how to put your iPhone on your Mac. That is a real feature, but it is the wrong way round. If you are on the couch and want to watch a render, read a terminal or click a button on your desktop from your phone, you need the Mac on the iPhone. Here is why Apple does not cover it, and the two routes that do.
What Apple offers, and why it is the wrong direction
iPhone Mirroring lets you use your iPhone from your Mac: the Mac shows the iPhone screen and you control it with the Mac mouse and keyboard. Apple lists macOS Sequoia 15 or later, iOS 18 or later, the same Apple Account on both, and the iPhone locked and near the Mac (checked October 2026). Nothing in it sends the Mac screen to the phone.
AirPlay is the other name people reach for. Apple's AirPlay guide covers sending a Mac screen to an Apple TV, a smart TV or another Mac, checked October 2026. An iPhone is not on that list. Sidecar, Apple's second-display feature, is iPad only, which we cover in Sidecar for iPhone: does it work. So Apple ships three screen features and the iPhone is on the receiving end of none of them.
That leaves two routes: Apple's own Screen Sharing paired with a viewer app from the App Store, or an app that serves the screen to your phone for you.
Route 1: macOS Screen Sharing plus a VNC viewer
Your Mac already has a screen server built in. It speaks VNC, a long-standing standard for viewing and controlling a computer over a network. Per Apple's Screen Sharing page (checked October 2026), VNC viewers can connect when you allow them with a password. Apple does not name an iPhone app, so you pick one yourself.
- On the Mac, open System Settings, click General, then Sharing.
- If Remote Management is on, turn it off. Apple says it cannot run at the same time as Screen Sharing.
- Click the Info button next to Screen Sharing and turn Screen Sharing on.
- Turn on "VNC viewers may control screen with password" and set a password. Use "Allow access for" to choose who can connect.
- Click Done. Note your Mac's name (it ends in .local) or its IP address.
- On the iPhone, install a VNC viewer from the App Store. Jump Desktop is one we have written up; others exist.
- Add a new connection in the viewer using the Mac's name or IP address, enter the password, and connect while both devices are on the same Wi-Fi.
This is free on the Mac side and gives you the full desktop. The honest costs: the viewer app is often paid, you set up a password yourself, and it only works on your home network unless you add something like a VPN. Opening a VNC port to the internet directly is a bad idea, so the away-from-home version is a bigger project than the steps above.
Route 2: MightyMouse, a QR scan and no viewer app
MightyMouse shows your Mac screen live on your iPhone and lets you drive it with a trackpad, keyboard and mic. The Mac app serves a control page and your phone opens it in Safari, so there is no viewer to install on the phone.
- Install MightyMouse on the Mac and turn on Phone Remote.
- A QR code appears on the Mac. Point your iPhone camera at it and open the link in Safari.
- The phone pairs once with a short code carried in the QR, then keeps its own credential, so later connections need no new scan.
- On the phone, open Settings and find the Screen section.
- Turn on "Show my Mac screen". Leave "Show" on "Same screen" for a mirror.
- Under "Video", pick Smoother or Sharper. Turn on "Computer audio" if you want the Mac's sound on the phone.
The first time, macOS asks for Screen Recording permission on the Mac. It can only be granted on the Mac itself, and without it the phone shows an error instead of a picture. After that, the mirror starts from the phone. Nothing on the Mac side can start one for you, which also means nobody can switch your screen on remotely without your phone asking.
Unlike a read-only mirror, the same page has the trackpad, so a tap on the phone moves the cursor and clicks on the Mac. See using your iPhone as a trackpad for your Mac for the gestures, and controlling your Mac from your iPhone for the wider picture.
Quality and lag: what you should expect
The mirror is a live video stream, not a cloud screenshot. The Mac encodes its screen and sends it to the phone peer to peer when it can. In the code, Smoother caps the picture at 1280 by 800 pixels, 20 frames a second, and about 1.5 megabits a second. Sharper allows up to about 4 megabits a second. Pick Smoother when text is readable and motion matters, Sharper when you are reading small type on a good connection.
We do not publish a latency number because we have not measured one we would stand behind. Every mirror has a round trip: your tap travels to the Mac and the picture travels back. On the same Wi-Fi it is small. On a weak cell signal it is noticeable. A 13 inch or 27 inch desktop squeezed onto a 6 inch phone is also small by nature, so this is for checking and nudging, not for a full day of work.
If the picture stops arriving, the phone shows a stalled notice and the Mac tries to recover on its own. If the connection cannot be made at all, it gives up after about 20 seconds rather than hanging.
Away from home
On your own Wi-Fi the phone and Mac connect directly and it is free and unlimited on every plan. Away from home the video needs a relay, because most cellular networks block a direct line to your Mac. MightyMouse fetches relay credentials for you, with no router setup or port forwarding. Free accounts get a monthly allowance of relay time (as of October 2026: 15 minutes a day, 45 a week and 90 a month), and Pro removes the limit. When the allowance runs out the mirror falls back to the direct path, which still works at home.
Which display, and a few hard limits
- One display at a time. There is no picker for which monitor the phone shows. If you have several displays, the Mac chooses, and it may not be the one you want. If you want the phone to be its own extra screen instead, that is the "Second screen" option, covered in using your iPhone as a second monitor for your Mac.
- Only the phone starts a mirror. You cannot press a button on the Mac to push its screen to the phone.
- A sleeping Mac cannot be mirrored. macOS turns the display off when it sleeps, and no remote tool reaches past that. MightyMouse can keep the Mac awake while the remote is on if you turn on Keep this Mac awake in Settings (it is off by default), and Away Mode holds it awake while your phone is connected, but neither can get past a lock screen that is already up. See waking a Mac remotely.
- No monitor? Plan for a dummy plug. A Mac mini with nothing plugged in may give macOS no screen to capture. We have not tested that case, so add a small HDMI dummy plug if the mirror comes up blank. See using a Mac mini without a monitor.
- Pinch to zoom is off. Do not expect to pinch the Mac screen bigger on the phone.
- macOS only for the Mac side.
What this costs you
Route 1 costs a viewer app, a password you manage, and no good way to reach the Mac away from home. Route 2 costs a Mac app install, a Screen Recording permission, and the relay allowance when you are off Wi-Fi. Both need the Mac awake and signed in, both show a desktop on a small screen, and neither is a replacement for sitting at the computer. If the Mac is in the same room and you can already see it, you do not need any of this; a trackpad alone is enough.
Which one to pick
- Want a free, one-off look at the screen on your home Wi-Fi and do not mind setup? Screen Sharing plus a VNC viewer.
- Want to scan once, see and steer the Mac, and reach it from outside the house? MightyMouse.
- Want a real second monitor? An iPad with Sidecar is built for that; see Sidecar for iPhone.

Common questions
Can you mirror a Mac to an iPhone?
Not with anything built in. Apple's iPhone Mirroring shows your iPhone on your Mac, and AirPlay sends to TVs and Macs. To see a Mac on an iPhone you need a VNC viewer app with macOS Screen Sharing, or an app like MightyMouse.
How do I mirror my MacBook to my iPhone?
Install MightyMouse on the MacBook, scan the QR code with your iPhone camera, then turn on Show my Mac screen in the phone Settings. The other route is turning on Screen Sharing in System Settings and connecting with a VNC viewer app.
Can I mirror a Mac mini to an iPhone?
Yes, while it is awake and signed in. We have not tested a Mac mini with nothing plugged in, and it may give macOS no screen to capture. A small HDMI dummy plug is the safe setup. It cannot be mirrored while asleep.
Does mirroring my Mac to my iPhone work away from home?
It can. MightyMouse uses a relay when you are off your own Wi-Fi, with a free monthly allowance and no router setup. A plain VNC connection needs a VPN or similar set up by you.
Can I choose which Mac monitor shows on my iPhone?
No. MightyMouse shows one display and has no monitor picker. If you want the phone to act as its own extra screen instead, it has a Second screen option.
Does the Mac need to stay awake to mirror to my iPhone?
Yes. A sleeping Mac has no screen to capture, and no remote tool can wake it through a lock screen that is already engaged. MightyMouse can keep it awake while the remote is on if you turn on Keep this Mac awake in Settings, which is off by default.
To see your Mac screen on your phone and steer it too: MightyMouse shows your Mac screen live on your iPhone with a trackpad, keyboard and mic, paired in one QR scan.
