See and control your Mac’s screen on your iPhone
Once connected, your iPhone shows your Mac’s screen live. It is more than a mirror: you can drive that Mac with the trackpad, by tapping directly, or with a game controller.
Why macOS can’t do this on its own
The Mac’s built-in Screen Mirroring only sends to an Apple TV, an AirPlay-capable TV or another Mac; an iPhone can’t receive it. macOS’s iPhone Mirroring goes the other way, putting your iPhone’s screen on the Mac. To see your Mac on your iPhone, you need an app like TouchNow.
Choosing which display to see
If your Mac has more than one display, tap “⋯” → “Choose Display” to switch between them. The same menu can also turn your iPhone into an extended display for the Mac.
Showing just one app
When you don’t want the whole desktop on screen, “⋯” → “Choose App” lets you pick one window and streams only that window; nothing else appears on your iPhone.
How smooth it is
On the same Wi-Fi it streams at up to 60 frames per second. If the picture stutters or looks soft, adjust it in the “Quality” menu; the trade-offs are explained in the latency and picture quality guide.
It keeps going when you switch apps
Go back to the Home Screen and your Mac’s screen shrinks into Picture in Picture and keeps playing; the Lock Screen also shows a live card while you’re connected.
Does it cost anything?
No. On the same Wi-Fi it is free, like every other feature. A subscription is only needed to reach your Mac from outside your home network.
