On June 13, 2003, Microsoft announced that it was ceasing further development of Internet Explorer for Mac and the final update was released on July 11, 2003. Later versions diverged, particularly with the release of version 5, which included the cutting-edge, fault-tolerant and highly standards-compliant Tasman layout engine.Īs a result of the five-year agreement between Apple and Microsoft in 1997, it was the default browser on the classic Mac OS and Mac OS X from 1998 until it was superseded by Apple's own Safari web browser in 2003 with the release of Mac OS X 10.3 'Panther'. Initial versions were developed from the same code base as Internet Explorer for Windows. Internet Explorer for Mac OS X (also referred to as Internet Explorer for Macintosh, Internet Explorer Macintosh Edition, Internet Explorer:mac or IE:mac) is a proprietary web browser developed by Microsoft for the Macintosh platform to browse web pages.
