Mouse Control Not Working During Screen Sharing on MacOS

Mouse control not working during screen sharing on macOS is usually caused by missing permissions for Remote Management or Screen Recording, or incorrect settings in the Sharing preferences. Ensuring the host Mac allows remote control and granting the necessary access rights to the controlling application typically resolves this connectivity issue immediately.

Verify Remote Control Permissions

The most common reason you cannot move the mouse or type on a shared Mac is that the system has blocked remote input for security reasons. macOS requires explicit permission for other users or applications to control the computer remotely. You must enable this feature in the Sharing settings before attempting a connection. Open System Settings and navigate to General, then click on Sharing. Locate the Remote Management option in the list of services. If it is not already active, toggle the switch to turn it on. Once enabled, click on the Computer Settings button located next to the toggle. A dialog box will appear asking who can control the computer. Select "All Users" if you want anyone with valid credentials to have full control, or choose "Only these users" if you prefer to restrict access to specific accounts. Ensure that the checkbox for "Allow remote control" is checked. This setting is critical because without it, the remote user can see the screen but cannot interact with it.

Check Screen Recording Access

While Remote Management handles input, some screen sharing tools also require Screen Recording permissions to function correctly, especially if they rely on accessibility features to simulate clicks. macOS isolates applications that need to monitor screen activity, so you must grant this privilege manually. Go to System Settings again and select Privacy & Security from the sidebar. Click on Screen Recording in the list of privacy categories. You will see a list of applications that have requested this permission. Look for the application you are using to initiate the screen share, such as Zoom, Teams, or VNC clients like RealVNC or TightVNC. If the app is not listed, click the plus button and add it from your Applications folder. Toggle the switch next to the app name to enable it. Restart the screen sharing application after making this change to ensure the new permissions take effect. Without this access, the remote session may be blacked out or unresponsive.

Review Network and Firewall Settings

Sometimes the permissions are correct, but the firewall blocks the incoming connection required for mouse control. macOS includes a built-in firewall that can interfere with remote management protocols. Navigate to System Settings > Network > Firewall. If the firewall is turned off, consider turning it on for better security, but ensure it is configured to allow incoming connections. Click on Options to view detailed settings. Make sure that "Automatically allow signed software to receive incoming connections" is selected. More importantly, look for entries related to Remote Management or VNC Server. These should be set to Allow Incoming Connections. If you are using a third-party router or network configuration, verify that ports 5900 (VNC) or 5901+ are open.

Test with a Simple Connection

To isolate whether the issue is with the specific application or the system-wide settings, try using the native Screen Sharing app provided by Apple. This eliminates variables introduced by third-party software. On the host Mac, ensure Remote Management is still enabled as described in the first section. On the client Mac, open Finder and go to Go > Connect to Server. Enter the address vnc://. When prompted, enter the username and password of an account on the host Mac that has been granted remote control permissions. Attempt to control the mouse. If this works, the issue lies with the third-party application's configuration. If it fails, the problem is likely at the OS level, possibly requiring a restart of the sharing service or a reboot of the host machine.

Update macOS and Software

Outdated software can contain bugs that affect peripheral handling and remote sessions. Apple frequently releases patches for stability and security in newer versions of macOS. Check for updates by going to System Settings > General > Software Update. Install any available updates for your operating system. Similarly, ensure that the screen sharing application on both the host and client machines is updated to its latest version. Developers often fix compatibility issues in major releases. After updating, log out and back into your user accounts on both devices to refresh the permission caches.

Frequently Asked Questions

Why can I see the screen but not move the mouse?

This indicates that the video stream is active, but the input channel is blocked. Check the Remote Management settings to ensure "Allow remote control" is enabled for the user account being used. Also, verify that the controlling application has Screen Recording permissions in Privacy & Security.

Does Screen Sharing work over Wi-Fi?

Yes, screen sharing works over Wi-Fi, but latency may be higher than on a wired Ethernet connection. High latency can make mouse movements feel sluggish or unresponsive. For critical tasks, a direct cable connection is recommended to minimize lag and packet loss.

What if I forgot the password for the host Mac?

You cannot regain mouse control without valid credentials. You will need to reset the password using Apple ID recovery, Recovery Mode, or an administrator account on the same network. Without access to an admin account, remote control remains impossible until authentication is restored.

Can I use Bluetooth mice for remote control?

Remote control sends input signals digitally, so it does not depend on the physical type of mouse connected to the host Mac. Whether the host uses a trackpad, USB mouse, or Bluetooth mouse, the remote user’s inputs are translated directly into cursor movements regardless of the hardware.

Is it safe to allow all users remote control?

Allowing all users increases the attack surface if unauthorized individuals obtain login credentials. It is safer to select "Only these users" and add only trusted accounts. Regularly review this list to remove former employees or unused accounts to maintain security hygiene.
