Fix File Sharing not working
Posted in
Some macOS users have found that file sharing between a Mac running macOS Ventura or Sonoma does not work reliably between such Mac and another Mac with older OS, iPhone, iPad, Windows PC, and even some NAS drives like Synology. For many users, file sharing setups that worked fine for years prior to updating to macOS Ventura or Sonoma are now no longer working at all or behaving in an inconsistent manner.
If you’re experiencing problems with file sharing not working in macOS Ventura or Sonoma, there is a fix to resolve the issue. This solution applies to SMB file sharing with macOS Ventura or Sonoma and devices connecting to or from the Mac, whether you’re experiencing connectivity failures, time outs, server unavailable, server may not exist, or other similar error messages.
• Open the "System Settings" on Mac from the Apple menu
• Go to "General" and then to "Sharing"
• Find the switch for "File Sharing" and toggle it Off
• Restart the Mac by going to the Apple menu and choosing Restart
• Upon reboot, return to the Sharing system settings panel and turn "File Sharing" back to the On position
• Resume file sharing as usual, it should work as expected
You may need to repeat this process after a few days, or at random, if file sharing suddenly stops working again between the macOS Ventura or Sonoma Mac and another Mac or device. Why you need to disable file sharing, reboot, then re-enable file sharing, is a bit of a mystery. Simply toggling file sharing off and on does not do the trick.
