Good morning. I recently upgraded to Sierra from Mavericks. Now, my 2013 MacBook Pro is no longer recognizing my Seagate Personal Cloud drive. There were no problems previously In Finder is shows "?" on the side panel, next to the name "Personal Cloud". When I attempt to connect, I get the error message "Network Connection failed. There was a problem connecting to personalcloud. The server may not exist or is unavailable at this time. Check your connection and try again." I can access the Personal Cloud via iOS and Windows 10, but not via my MacBook. Any assistance would be appreciated.
