Safari

Hi Phil. Your question is a little confused, so if I haven't answered what you meant to ask do tell me. I assume you are talking about Safari on Mac? Safari is the default web browser on Mac, however you can use other browsers such as Chrome if you wish. Within Safari, the default search engine is Google, but if you prefer you can change this to Yahoo or Bing. This option can be found by pressing Command+Option+M to go to the menu bar, then navigate right to Safari and go down to Preferences. Or while in Safari simply press Command+Comma. In the Preferences window, you can change the search engine in the General tab. I would say that there is no answer to which of these search engines works best with Safari, they all work in the same way. It simply depends which search engine you prefer to get your search results from. As I said, if this isn't helpful do let me know.
