Change Siri's default search engine on macOS I recently upgraded my MacBook Pro to macOS Sierra and now have access to Siri. Whenever Siri searches the internet, it uses Bing, although I would prefer to use Google.

I changed Safari's default search engine to Google, but that did not affect Siri's searches.

How can I change Siri's default search engine?
At this time, there's no way to change the default macOS Siri search engine.

I would recommend letting Apple know you'd like the ability to change the search engine using the macOS Feedback page.
