How to Fix Mac Screen Sharing Not Working Issue

If you share screen on FaceTime Mac and the screen sharing option is not working, below are the five efficient methods to fix it immediately. Before diving into the details of each solution, look at this table for some know-how.

Method 1. Share Mac Screen by Recording

The leading method to overcome the problem of screen sharing not working on Mac is recording it before sharing. EaseUS RecExperts is a comprehensive and secure Mac screen recorder in the market to help you with this task.

Share Mac screen by recording

This software helps you record all your screen activities with a webcam if you want to capture yourself. You can flexibly capture the full screen or a custom region per your needs. Its advanced green screen technology allows you to create tutorials, gameplay videos, presentations, and more. Capturing your image from the webcam is also in your control. You can even record microphone voice, internal sound, or no audio at all.

In addition, it lets you adjust the output parameters, like format, frame rate, quality, etc. You can also adjust playback, extract audio, or trim your recorded videos with its editing toolkit. Lastly, you can capture videos without any time limit, and your recordings will be free of any watermark.

Method 2. Uncheck the Remote Management Feature

Besides screen sharing, remote management lets you access Macbooks from other devices. However, the problem is you can't activate both features simultaneously. You must deactivate the remote management to enable the screen-sharing function. Here are the steps to perform this task:

Step 1. Tap the "Apple" menu icon to unlock the "System Preferences" tab.

Step 1 to Uncheck Remote Management

Step 2. Next, you have to choose the "Sharing" button. Scroll down the list under the "Service" section.

Step 2 to Uncheck Remote Management

Step 3. Finally, uncheck the "Remote Management" option to disable this feature.

Method 3. Access the Administrator Account

Not using an admin account is one of the reasons behind the situation when you ask why I can't share the screen on Mac. Although you may have it on your Mac, you might not be using it because you are using the shared computer or for any other reason.

So whenever you face the issue of the Apple macOS Sonoma screen sharing not working, the solution is to log into the administrator account. Let's check it once by following the below tutorial.

Step 1. After going under the "System Preferences" section, press "Users & Groups."

Step 1 to Access Administrator Account

Step 2. Now, click the admin account username and type your password, and you will be ready to share the screen on Mac.

Method 4. Adjust your Mac Sleep Mode

Have you ever experienced a situation when your Macbook falls asleep, thus interrupting your screen share session? If yes, it's because one of your systems has fallen asleep. So, you must turn off all the screen-locking features before sharing your screen.

Step 1. Tap the "Battery" icon from the menu bar and press "Battery Preferences." You can also open this window by clicking "System Preferences"> "Battery."

Step 1 to Change Mac Sleep Mode

Step 2. Now, you have to increase the time duration to 30 minutes, 1 hour, or more by moving the slider from left to right.

Step 3. Press the "Power Adapter" button to extend the display timeout. You are all done!

Step 3 to Change Mac Sleep Mode

Method 5. Update your macOS

Updating any device is crucial for proper functioning; the same goes for Mac. Although you should have activated the feature of automatically keeping your Mac up to date, this needs to be checked before if you are facing the black screen while screen mirroring. It will help you get rid of the bugs and other issues, like Mac screen sharing not working.

Step 1. After connecting your Mac to the internet, open the Apple menu.

Step 2. Press the "System Preferences" tab > "Software Update."

Step 3. Finally, if available, hit the "Update Now" or "Upgrade Now" button. That's all!
