Safari utilizes Apple's brushed metal user interface, a bookmark management scheme that functions like the iTunes jukebox software, is integrated with Apple's QuickTime multimedia technology and features a tabbed-browsing interface similar to that of Mozilla. A Google search box is a standard component of the Safari interface, as are software services which automatically fill out Web forms and which spellcheck entries into web page text fields.
Safari Beta 1 was released at the 2003 Macworld conference, and was refreshed in the spring of 2003. Version 1.0 was released in June 2003, and was compatible with Mac OS X 10.2 Jaguar and later. Safari version 1.1 was included with Mac OS X 10.3 Panther, which was released on October 24, 2003. Version 1.1 included several rendering improvements, and was the first version of Safari to be set as the Mac's default browser.
Prior to 1997, Apple Macintosh computers had shipped with Netscape Navigator. Microsoft's Internet Explorer was included as the default web browser since then. In June 2003, Microsoft announced it would discontinue development of Internet Explorer for Macintosh. Internet Explorer is included with OS X 10.3, but is no longer the default browser.
