Safari User Guide
Safari has been Apple's Web browser for many years, and the company keeps making improvements to it at regular intervals. Originally designed to be a Web browser with the Mac OS look and feel. In Safari on your Mac, clear cookies and website data for some or all websites. Control which cookies and website data you allow. Safari 2.0.4 was the last version to be released exclusively on Mac OS X. On January 9, 2007, at Macworld SF, Jobs announced the iPhone. The device's operating system (later called iPhone OS and subsequently renamed to iOS) used a mobile version of the Safari browser and was able to display full, desktop-class websites. Before you start, check the version of Safari running on your Mac. To display the version number, choose Safari About Safari. If your Safari version is 11.0 or later, follow the steps in For Mac OS X 10.11, macOS 10.12, and later. If your Safari version is 10.0 or later, follow the steps in For Mac OS X 10.10. Music, TV, and podcasts take center stage. ITunes forever changed the way people experienced.
