Securing Your Mac Sharing Settings

Step by step

   Open the Sharing system settings

   Click the Apple menu in the top-left corner of your screen and select System Settings. Navigate to General in the sidebar, then click Sharing to view your current network exposure.

   Disable inactive sharing services

   Scan the list of services such as File Sharing, Screen Sharing, and Media Sharing. Click the toggle switch next to every service that is not currently required for your daily workflow to turn it off.

   Note: Turning off unused services immediately hides your Mac from local network discovery.

   Restrict File Sharing permissions

   If File Sharing must remain active, click the Info (i) button next to it. Review the Shared Folders list and the Users assigned access, ensuring no unauthorized accounts have Read & Write permissions.

   Audit Screen Sharing access

   Select the Info (i) button for Screen Sharing. Ensure 'Allow access for' is set to 'Only these users' rather than 'All users' to prevent unauthorized remote connections.
