Currently I have a Nokia 6300 and a Mac with Mountain Lion installed. Calendar and Contacts sync through iSync via Bluetooth without a problem.
I'm thinking of upgrading to Mavericks or Yosemite, but as these newer OS'es miss the syncing services necessary for iSync to work I wouldn't be able to connect my Nokia anymore.
I don't want to buy a smartphone just so it will sync with my Mac, so therefore I'm looking for a "dumbphone" that can sync with my Mac on Mavericks or Yosemite.
So my question is:
Does a dumbphone exist that will be able to sync contacts and calendars with a Mac on Mavericks or Yosemite? It's fine if a third-party application is needed.
