When you type a phrase into the address bar or search box of a web browser, the term is sent to the browser’s default search engine. The search engine can be Google, Bing, Yahoo, or many others, depending on the configuration of the browser you’re using on your Mac. It’s easy to change the default search engine to another search engine.
