Hi. I'm thinking of upgrading from Snow Leopard to Mountain Lion but have a privacy concern around the iCloud functionality of Safari. Whilst I can see the advantages of having transparency of browsing history being made available across multiple devices, I can also see times when I don't want this to happen... eg. researching a present for my wife, sharing content on my childrens' devices intended for us etc etc. Can this be turned off (would prefer not to use the private browsing function as this limits the functionality of some websites) Thanks for your help.
