3. Mac Mini and Network Attached Storage Issues

Listener: Bruce

Bruce shares his experience after switching from a 2019 27-inch iMac to a new M4 Mac Mini equipped with 16GB RAM and a 1TB SSD. Connected to a Synology DS120J NAS for Time Machine backups, he encounters frequent disconnections requiring re-entry of credentials upon logging back in or waking the Mac Mini from sleep.

Micah's Suggestions:

• Credential Management:

  • Keychain Access: Bruce should inspect and reset the NAS credentials in Keychain Access to ensure they're stored correctly. Deleting and re-entering the credentials can resolve authentication issues.

• System Settings Adjustments:

  • Energy Settings: Ensure that "Wake for Network Access" is enabled in the Energy settings to allow the Mac Mini to maintain network connections during sleep.
  • AutoMounter Configuration: Verify that AutoMounter is set to reconnect automatically upon system wake or login.

• Advanced Troubleshooting:

  • Reset Network Preferences: If issues persist, resetting network preferences by deleting specific plist files can resolve corrupted network configurations.
  • Console Logs: Utilizing the Console app to monitor system logs can help identify underlying issues related to network disconnections or AutoMounter failures.
