I gave my parents my old iMac to use so they can start browsing the web. However, every time they start to type in a web address and safari butts in with its autocomplete history, it confuses the heck out of them and they don't know what to do. So basically I want to completely disable Safari's history, or at the very least, its autocomplete feature. I've looked everywhere and can't find the option for this. Could anyone assist?
