Hi I'm no good with Mac... I'm a Windows guy through and through, let's just get that one out of the way Anyway. My gf's mum wants to find a way of blocking the ability to clear the browsing history/cache in Safari on their Mac, so that my gf's brother can't look at dodgy sites and then clear the browser history. I know options exist but I wonder what would be best? They've just got the one iMac and they only have one user account and just leave it turned on/logged in the whole time. I assume you would have to create more user accounts and make them limited users, password protect the main "admin" account and then do something to disable the option(s) in Safari? OR alternatively get parental control software or some kind of monitoring software... HOWEVER he's one of those young teens who's jailbroken his iPod before the age of 14 and will probably find a way around it so does anyone have any suggestions for something that's hard to crack and easy enough to set up for a Mac novice such as myself? :$ Any help appreciated. Thanks!!
