Are you encountering issues with screen sharing on your MacBook running macOS Sonoma?
Screen sharing is a valuable feature that allows users to remotely access and control another Mac over a network.
However, it can be frustrating when it doesn’t work as expected.
In this blog, we will provide you with comprehensive troubleshooting steps to get your MacBook screen sharing back on track.
How To Fix MacBook Screen Sharing Not Working On MacOS Sonoma?
To fix MacBook screen sharing not working on macOS Sonoma, you can verify network connections, disable remote management, restart your Mac. Additionally, you can ensure screen sharing is enabled and permissions are correct and adjust sleep settings.
1. Verify Network Connection
A stable network connection is crucial for screen sharing. Both Macs must be on the same network to communicate with each other.
- On each Mac, click the Apple menu and select “System Settings.“
- Scroll down and click “Network” in the sidebar.
- Check that the indicator next to your network connection type (e.g., Ethernet or Wi-Fi) is green, indicating a good connection.
- If you’re using Wi-Fi, ensure both Macs are connected to the same network by clicking “Wi-Fi” and verifying the network name.
- With both Macs on the same network and connected properly, try to share the screen again.
2. Disable Remote Management
When Screen Sharing is not functioning as expected on macOS Sonoma, it may be due to Remote Management settings interfering with Screen Sharing preferences.
Disabling Remote Management can eliminate this conflict, allowing Screen Sharing to work properly.
- Click on the Apple logo at the top left corner of your screen.
- Select “System Preferences” from the drop-down menu.
- Navigate to “Sharing” settings.
- Uncheck “Remote Management” if it is selected.
- Try initiating Screen Sharing again to see if the issue has been resolved.
3. Restart Your Mac
A simple restart can often resolve underlying issues by refreshing the system’s processes. Restarting your Mac can clear temporary glitches affecting Screen Sharing.
- Click the Apple logo at the top left corner of the screen.
- Select Restart from the drop-down menu.
- Wait for your Mac to reboot completely.
- Once restarted, attempt to use Screen Sharing again.
4. Ensure Screen Sharing Is Enabled And Permissions Are Correct
If Screen Sharing or Remote Management isn’t turned on, or if the sharing permissions aren’t set up correctly on the Mac whose screen you want to share, it won’t be possible to share screens between Macs.
- On the Mac you want to share, click the Apple menu and select “System Settings.“
- Click “General” in the sidebar, then click “Sharing” on the right.
- Click the Info button next to Screen Sharing.
- Ensure that Screen Sharing is toggled on.
- In the Screen Sharing settings, add your user to the list of allowed users if it’s not already there.
- After adjusting these settings, try to initiate a screen sharing session again.
5. Adjust Sleep Settings
If either Mac goes into sleep mode, it can disrupt the ability to share screens.
Adjusting sleep settings ensures that both Macs remain awake and available for screen sharing.
- On each Mac, go to the Apple menu and select “System Settings.“
- Search for “Energy Saver,” “Battery,” or “Power Adapter” settings, depending on your macOS version.
- Adjust the settings to prevent the Mac from going to sleep too quickly or choose an option that keeps the Mac awake when necessary.
- Once both Macs are configured to stay awake, attempt to share the screen again.
6. Disable And Re-enable Screen Sharing
Toggling Screen Sharing off and on can sometimes resolve temporary glitches or connectivity issues.
- Go to “System Preferences” and select “Sharing.“
- Uncheck “Screen Sharing” to turn it off.
- Wait a few seconds and then recheck “Screen Sharing” to turn it back on.
- Attempt to initiate a Screen Sharing session once again.
7. Change Or Turn Off The Firewall
The Firewall might be blocking incoming connections for Screen Sharing, preventing it from working properly.
- Open “System Preferences” and click on “Security & Privacy.“
- Go to the “Firewall” tab and unlock the padlock if necessary by entering your admin password.
- Click “Firewall Options” and ensure that “Block all incoming connections” is not selected.
- Make sure “Screen Sharing” (or “Remote Management“) is allowed in the list of applications.
- If you’ve made changes, click “OK” and try Screen Sharing again.
8. Contact Apple Support
If none of the previous fixes resolve the issue with Screen Sharing on your Mac, there may be a more complex problem at hand.
Contacting Apple Support can provide you with professional assistance and potentially uncover deeper system issues or bugs that are not easily resolved through standard troubleshooting.
