How to Use Messages to Share Your Screen With Others in macOS

Messages App icon in macOS Big Sur

You can use Apple’s Messages app on your Mac to share your screen with another person who’s also using the app. Conversely, they can share their screen with you.


Start Screen Sharing

Launch the Messages app on your Mac and send a message to a person with whom you wish to share.

Then…

Invite to share screen in macOS Messages app
  • Click the details button information circle icon
    You can search for contacts and content in conversations by clicking in the Search field in the top-left corner and enter the name of a person. Or you can choose from the suggested contacts, links, photos, and more.
    (Note that you can’t send a message to anyone restricted by communication limits in Screen Time.)
  • Click the Share button
    Choose to share your screen (choose “Invite to Share my Screen”) or view the other person’s screen (choose “Ask to Share Screen”).

waiting for response

 

When the screen-sharing request is accepted, an audio call is launched (so you can talk with your screen share) and the Screen Sharing app launches.

You can pause screen sharing at any time by clicking in the menu bar and choosing Pause Screen Sharing. Choose it again to start sharing your screen again.


Stop Screen Sharing

You can stop screen sharing whenever you want.

  • Click in the menu bar
  • Choose End Screen Sharing.

If you’re viewing your friend’s screen: Choose “Screen Sharing > Quit Screen Sharing.”


Block Sharing Requests

If you’re getting screen sharing requests from someone you don’t wish to share your screen with, you can shut ‘em down. When they send you an invitation, hold the pointer over the Decline button, click, then click Block User.


Troubleshooting Screen Sharing

If you’re having problems implementing screen sharing, there are a couple of things you can try.

  • Make sure the person youʼre trying to share with is signed in to iCloud using the same Apple ID they used to sign in to Messages. (I’m assuming you’ve made sure that you’re doing the same.)
  • If they can’t sign in to iCloud and Messages using the same Apple ID, open your Contacts app, and make sure your contact card for the person includes both Apple IDs—the one they use to sign in to iCloud, and the one they use in Messages. Then try sharing again.

  • This just allows me to view the other person’s screen? I cannot control the other person’s computer, correct?

    Important distinction.

  • In my house I have 3 macs and use the built-in Screen Sharing app all the time (which is what using this technique in iMessage invokes), using the house’s networking, and it works fine. However, when I try to use this to screen-share with someone over the Internet the performance is so abysmal it borders on dangerous; it’s so slow you cannot accurately control or predict where you mouse is going and that can result in a disastrous mistake with drag ‘n drop, for example. However, programs like TeamViewer work great and are a much-preferred choice. TeamViewer is free if you are using it for non-commercial purposes to help family and friends. But I would prefer to have Apple’s builtin ScreenSharing as a workable backup resource.

    Can you comment on why Apple’s offering performs so poorly over the internet and what you can do to improve it ?
