Apple switches from Bing to Google as its default search partner for Siri, Search inside iOS (earlier called Spotlight) and Spotlight on the Mac. An Apple statement read, “Switching to Google as the web search provider for Siri, Search within iOS and Spotlight on Mac will allow these services to have a consistent web search experience with the default in Safari. We have strong relationships with Google and Microsoft and remain committed to delivering the best user experience possible.”
Google search is already the default provider for Safari on Mac and iOS. All Google searches on Apple will be encrypted and anonymized, quite opposite to the regular Google searches. Google has been Apple’s search partner earlier, though the stint was short and Google was replaced by Bing in 2013.
