Safari is used by 14.9% of all internet users, according to data from StatCounter. The tracking prevention system will also arrive on Apple’s computers 25 September, as part of the High Sierra update to macOS. It will include a new default feature for the Safari web browser dubbed “intelligent tracking prevention”, which prevents certain websites from tracking users around the net, in effect blocking those annoying ads that follow you everywhere you visit. IOS 11, the latest version of Apple’s operating system for mobile devices, will hit users’ phones and tablets on Tuesday. For the second time in as many years, internet advertisers are facing unprecedented disruption to their business model thanks to a new feature in a forthcoming Apple software update.
