what is the purpose of "back to my mac"? doesn't icloud already sync information from my other devices to my computer?
What is the purpose of selecting "back to my mac" on icloud? My husband and I share an IMac and an IPad and each of us has a new IPhone. I thought that ICloud automatically synced whatevever is entered into whatever device is being used (in our cases contacts and calendars) to our IMac and other devices.
