During an active FaceTime call, screen sharing is enabled by tapping the call controls, choosing Screen Sharing, then Share My Screen — a three-second countdown runs before your iPhone or iPad display appears for everyone on the call.
One wrong tap opens the wrong menu, and screen sharing hides behind a control most people never touch until they need it. The feature arrived with iOS 15.1 and iPadOS 15.1, and it’s built into every current iPhone, iPad, and Mac — no subscription, no extra app, just a call that’s already connected. Whether you’re helping a parent navigate settings or walking a coworker through a document, the route is the same: start the call, find the More button, and tap Screen Sharing.
Why FaceTime Screen Sharing Might Be Missing From Your Controls
If the Screen Sharing option doesn’t appear during your FaceTime call, the device almost certainly isn’t running a current-enough operating system. FaceTime screen sharing requires iOS 15.1 or iPadOS 15.1 on mobile devices and a matching version of macOS on a Mac. Devices still on iOS 15.0 or older won’t show the option at all — the feature was added in the 15.1 update, not the initial iOS 15 release.
The fix is a simple software update: open Settings → General → Software Update and install the latest available version before starting the call. Once updated, the Screen Sharing option appears inside the active call’s control panel, no additional setup required.
How To Share Your Screen On iPhone During A FaceTime Call
The actual sharing step takes about five seconds total, and you’ll see exactly what the other person sees after a brief countdown. Here’s the exact sequence on an iPhone or iPad running iOS 15.1 or later:
- Start or join a FaceTime call as usual.
- Tap the screen to reveal the call controls if they aren’t visible.
- Tap the More button — the three dots inside a circle icon.
- Tap Screen Sharing from the menu that appears.
- Tap Share My Screen.
- A countdown runs from 3 to 1, then your screen becomes visible to everyone on the call.
A blue bar appears at the top of your display reading “Screen Sharing” in white text, and the call participant list shows a small screen icon next to your name.
To stop sharing, tap More again, then tap Stop next to Screen Sharing. Ending the FaceTime call also ends screen sharing automatically. Apple’s official iPhone guide documents the same steps under the Screen Sharing section of the FaceTime controls.Apple’s FaceTime screen sharing guide provides the full walkthrough.
How Screen Sharing Works On A Mac
On a Mac running a modern version of macOS, the feature works similarly but adds a useful choice: you can share just one window instead of your entire desktop. During an active FaceTime call, the screen-sharing option lives in the FaceTime menu bar or the call controls panel.
Apple’s macOS documentation gives you two options after selecting Screen Sharing:
- Share This Window — shares only the specific app window you select; everything else stays private.
- Share This Screen — shares your full display, including the menu bar and desktop.
The same countdown runs before sharing begins, and the stop process mirrors iPhone: locate the screen-sharing indicator in the menu bar or FaceTime window and click Stop. PopSci’s guide on FaceTime screen sharing notes that the window-versus-full-screen distinction is the main difference between Mac and iPhone workflows.Macworld’s FaceTime screen-sharing breakdown covers the interface choices in more detail.
| Device | Sharing Options | How To Start |
|---|---|---|
| iPhone / iPad (iOS 15.1+) | Full screen only | More → Screen Sharing → Share My Screen |
| Mac (macOS 12+) | Window or full screen | Call controls → Screen Sharing → choose window or screen |
| Receiving end (any) | Can ask to share their own screen | More → Screen Sharing → Ask to Share Screen |
| Required OS version | iOS 15.1 / iPadOS 15.1 / macOS 12+ | Check in Settings → General → Software Update |
| Availability during call? | Yes — feature only appears after call starts | Tap screen to show controls if hidden |
| Stopping method | More → Stop next to Screen Sharing, or end call | Blue bar at screen top confirms active sharing |
| Audio continues during share? | Yes — regular FaceTime audio stays active | Call continues normally; sharing is visual only |
What To Do When Screen Sharing Won’t Start
When the Screen Sharing option is grayed out or missing entirely, the problem almost always traces back to one of three causes — and each has a straightforward fix.
- Device needs updating: If the Screen Sharing option doesn’t show up, open Settings → General → Software Update. iOS 15.1 or later is required; devices on 15.0 or earlier simply lack the feature.
- Not in an active call: Screen sharing only appears inside the call controls while a FaceTime call is connected. There is no way to start sharing from the FaceTime main screen or from Settings.
- Looking at the wrong UI: Older versions of FaceTime had a Share button or a different menu layout. The current interface uses the More button (three dots) → Screen Sharing → Share My Screen. If you’re looking for a three-dot menu or a share icon alone, the option has been reorganized.

Can Someone On The Call Share Their Screen Instead?
Yes — anyone on an active FaceTime call can share their own screen, not just the person who started the call. Apple’s controls include an Ask to Share Screen option that lets another participant request control of the shared view. The person currently sharing sees the request and can accept or decline.
This is particularly useful when troubleshooting or collaborating: one person can share their screen to show a problem, then the other can ask to share theirs to demonstrate the fix. The feature works identically on iPhone, iPad, and Mac — the Ask to Share option appears under the same Screen Sharing menu inside the call controls. OS version requirements apply to all participants; if one person’s device isn’t updated, that participant may see the Ask option grayed out.
| Issue | Likely Cause | Quick Fix |
|---|---|---|
| Screen Sharing option missing | iOS or iPadOS below 15.1 | Update via Settings → General → Software Update |
| Option grayed out | Not in an active FaceTime call | Start or join a call first, then check controls |
| Looked for a different button | Old interface memory | Tap More (three dots) → Screen Sharing → Share My Screen |
| Sharing stops unexpectedly | Call dropped or ended | Rejoin call and restart screen sharing |
| Other person can’t see screen | Their device not updated | Ask them to update to iOS 15.1 or later |
| “Ask to Share” no response | Current sharer hasn’t accepted | Wait for the Accept prompt on the sharer’s device |
Checklist For Your First FaceTime Screen Share
Before you tap Share My Screen for the first time, run through these four checks so nothing surprises you mid-call. The whole sequence takes under ten seconds once the call is connected, and the countdown gives you a moment to confirm everything looks right before sharing begins.
- Your iPhone, iPad, or Mac is running iOS 15.1 / iPadOS 15.1 / macOS 12 or later — check in Settings → General → Software Update.
- The FaceTime call is already connected and active — the Screen Sharing option won’t appear before the call starts.
- You know which device you’re sharing from — iPhone shares the entire screen; Mac lets you share one window or the full display.
- The person you’re calling also has FaceTime screen sharing support on their device — otherwise, they’ll see a static notification or the call won’t let sharing activate.
Final tip: The most common first-time mistake is tapping the screen once and looking for a share icon rather than the More button. Tap firmly enough to wake the controls, look for the three dots, and the Screen Sharing option is right there — no buried settings, no special permissions, just a working feature that takes a count of three to start.
