FaceTime screen sharing fails when SharePlay is off, software is outdated, restrictions apply, or web joiners are used; update and enable SharePlay.
FaceTime screen sharing should be simple: tap the button, show your screen, and carry on. When the button is missing, grayed out, or nothing shows to the other side, the cause is usually small and fixable. This guide walks you through quick checks, proven fixes, and safe ways to share from iPhone, iPad, and Mac.
Quick Checks Before You Start
Run through these fast checks first. They clear most hiccups in minutes and save you from chasing rare edge cases.
- Everyone uses an Apple device signed in with Apple ID. Web guests on Android or Windows can join a call but can’t start or share a screen.
- All devices meet the minimum versions for SharePlay. Update iOS, iPadOS, or macOS if in doubt.
- SharePlay is on in Settings > FaceTime (iPhone or iPad) or FaceTime > Settings > SharePlay (Mac).
- Screen Time or parental controls aren’t blocking FaceTime or SharePlay.
- Wi-Fi or cellular data is stable. If video stutters, switch networks or move closer to the router.
Fast Diagnosis Table
| Symptom | Likely Cause | Quick Fix |
|---|---|---|
| “Share My Screen” missing | Old system or calling from web link on non-Apple device | Update the Apple device; join from iPhone, iPad, or Mac |
| Button is grayed out | SharePlay off or Screen Time limits | Enable SharePlay; allow FaceTime and SharePlay in Screen Time |
| Other side sees black screen | DRM content or app blocks capture | Share a different app or use the app’s own SharePlay support |
| Share starts, then drops | Weak connection or low device resources | Close heavy apps; try Wi-Fi; plug in the device |
| Audio blasts or echoes | Media audio mixing with call | Lower app volume; use headphones; pause background media |

Facetime Can’t Share Screen: Fixes That Work
1) Confirm Device And Version Support
Screen sharing runs through SharePlay. It arrived on iPhone and iPad with iOS 15.1 and on Mac with macOS 12.1. If anyone in the call is on an older system, the Share button may vanish or fail. Open Settings > General > Software Update on iPhone or iPad, or System Settings > General > Software Update on Mac, and install pending updates. After updating, restart the device for a clean start.
2) Turn On SharePlay Where It Lives
On iPhone or iPad, go to Settings > FaceTime > SharePlay and switch it on. On Mac, open FaceTime, choose Settings, then SharePlay. Some apps can start SharePlay automatically; toggling the setting off and back on refreshes permissions and resolves stuck controls.
3) Check Who’s In The Call
Only Apple devices can share a screen in FaceTime. Friends joining from a browser on Android or Windows can watch and talk, yet they can’t share their own screen or host a SharePlay session. If the presenter is on the web, ask them to switch to an iPhone, iPad, or Mac.
4) Lift Screen Time And Parental Limits
Screen Time can hide or disable FaceTime and SharePlay. On the device, open Settings > Screen Time. Look under Content & Privacy Restrictions, then Allowed Apps and App & Feature Restrictions. Make sure FaceTime and SharePlay are allowed. On a managed child device, the parent may need to adjust settings first.
5) Know App And Content Limits
Some apps block capture to protect content. If the other side sees a blank player while audio keeps flowing, the app likely forbids screen capture. Switch to sharing the app’s interface, use a built-in SharePlay integration, or pick different content that allows sharing.
6) Steady The Connection
Screen sharing needs bandwidth and low latency. If video or taps lag, move to a stronger Wi-Fi band, toggle Airplane Mode off and on, or reboot the router. Close downloads, cloud backups, and VPNs that chew through bandwidth. On mobile data, check that FaceTime is allowed to use cellular.
7) Restart FaceTime Services
Small service glitches can break the Share sheet. Turn FaceTime off and back on in Settings > FaceTime. Sign out, then sign in again with the same Apple ID. Force-quit FaceTime and reopen it. A full device restart helps clear cached states that mute screen capture.
8) Tidy Power And Focus Settings
Low Power Mode can throttle background tasks. Turn it off while presenting. If Focus silences calls or hides alerts, people may miss the SharePlay prompt. Switch to a Focus that allows FaceTime, or turn Focus off during the session.
9) Share A Window Instead Of The Whole Screen (Mac)
On Mac, you can share one window or the entire screen. If a single app fails, share a specific window for that app. If the viewer needs to follow across apps, share the full screen and keep private items closed.
10) Use The App’s Own SharePlay
Music and video apps with SharePlay support keep streams in sync and hide protected video from the raw screen share. Start the media in the app and pick SharePlay when prompted, or add content through the FaceTime controls if the app advertises SharePlay.
11) Reset Network Settings (Last Resort)
If nothing else works, reset network settings on iPhone or iPad: Settings > General > Transfer or Reset > Reset > Reset Network Settings. Reconnect to Wi-Fi and try again. On Mac, remove and re-add the Wi-Fi service in Network settings, then reboot.

Version And Settings Cheat Sheet
| Device | Minimum Version For SharePlay | Where To Check |
|---|---|---|

| Mac | macOS 12.1 or later | System Settings > General > Software Update |
Troubleshooting By Scenario
When Only One Person Can Share
If only one person can share, the other is likely on a web link, on old software, or blocked by Screen Time. Move that person to an Apple device, update, and allow SharePlay. If a managed profile is in place from school or work, the admin may need to allow FaceTime features.
When The Screen Goes Black During Streaming
Premium video apps often block screen capture. Use the app’s SharePlay tile so everyone can watch with synced controls. If the app doesn’t list SharePlay, pick content that allows sharing or switch to a quick demo without protected video.
When You Need Hands-On Help
In a one-to-one call, you can let a trusted person point or even control your screen for a moment. Accept the prompt only from people you trust, and end control as soon as the task is done.
Clean Setup Checklist
- Update each device to the version listed in the table above.
- Turn on SharePlay in FaceTime settings.
- Confirm no Screen Time blocks for FaceTime or SharePlay.
- Ask web guests to rejoin from an Apple device.
- Test with a simple app first, then try media with SharePlay.
- Close downloads, VPNs, and heavy apps; switch to stable Wi-Fi.
- Restart devices if controls still misbehave.
Still Stuck? Try A Fresh Session
Create a new FaceTime link, invite one person first, and verify the Share button appears. Add others after the share starts. If it breaks as the group grows, one member’s device or settings are blocking SharePlay. Remove guests one by one until it stabilizes, then coach the affected person to update, enable SharePlay, and lift any limits.
Smart Habits For Smooth Shares
- Plug in while sharing on battery to avoid throttling.
- Keep a tidy Home Screen page with the apps you plan to demo.
- Use headphones to keep call audio clear for everyone.
- When teaching, zoom the screen for readability and speak your taps.
