Apple makes it easy to share your screen with other Mac users. You might expect this screen-sharing feature to live in FaceTime—the video-calling app on your Mac—but you’ll actually find it in the Messages app instead.
In short, screen sharing allows another person to view or use your computer with you. Your desktop shows up on that person’s screen so you can both see the same content. If you want, you can let that person take control of your computer as well.
Share screen using Facetime iMessages
There is a built in messaging application present in your Mac device i.e. the iMessage application.
The person, whom you want to give full control or want to share your screen with, must be a trustworthy individual.

So if you want to share Mac screen or want to show something in your friend’s Mac device, you can do so easily by the following the below steps:
The first step that you need to follow is to open the messages app on your device.
You first need to make sure Messages is set up to use your Apple ID. You almost certainly did this when you created an account on your Mac, but to double-check, open up Messages and go to Messages > Preferences > iMessage from the menu bar.
If you aren’t signed in, Messages asks for your Apple ID and password. If you are signed in, make sure Messages shows the correct account at the top of the window.

Once you have opened it, you now have to locate the conversation with the recipient. If you do not have a conversation, then you need to start one by sending a message to the recipient.

On the upper right corner of your screen, you will see an option of “details”, you need to click on that option to proceed.
Once done, you need to tap the double-screen option.

You will now get an option where you have to choose who takes over whose screen. If you want to choose their screen, you need to select that and if you want them to take over your screen, you need to select that.

The other person will see a request on his screen. To proceed, he has to either accept or decline.
With that, you can share your screen on FaceTime.
How To Take Control Of Other Facetime Screen During An Active Mac Screen Share Session ?
During the screen sharing session, you may ask for full control to other participant and vice versa. Thus Mac allows Screen controls with permissions. For this, the other person needs to click the Screen Sharing icon (click in the menu bar) and choose ” Allow [person] to control my screen ”. Then the person need to accept one notification .
Thus you can now have full control of the other person’s Mac device. Now if you want to add someone else also in the call, just follow the above steps (step 4 to 8) and start a screen sharing session right away. (again select contact, click on screen sharing option, then you can see a check mark for the contacts you selected )

Now you’ll need to choose who to share your screen with, you can choose All Users or Only these users. All Users is great if, for example, your Mac is connected to a network server at work or school and you’d like to screen share with anyone on that server. Only these users is the right choice for someone who’d like to share with just a few select people.
If you can’t share facetime screen
In the Messages app on your Mac, if the Screen Share button is dimmed, try the following:
- 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.
- 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.
