How to Make Safari Your Default Browser. If you have multiple Web browsers installed on your computer, you will need to specify which one you want to use as your default Web browser. Since Safari is Apple's newest and most sophisticated Web browser, Macintosh users will often choose to download Safari and make it their default Web browser. Choosing Safari as your default Web browser will make it so that Safari is the first program that opens every time you access the Web. There are two ways in which to set up Safari as your default browser. You can either change it through your computer's 'Preferences' window, or directly within Safari itself.
Go to Apple's main Web site (see Resources below).
