Apple's development team also casually referred to it as 'iBrowse' prior to Safari being the chosen name. For over a year internally the browser was known as 'Alexander' as this name was used in the string for codes and resources. Prior to the name Safari being used, a couple others were drafted including 'Freedom'. Microsoft ultimately released a Mac OS X edition of Internet Explorer for Mac, which was included as the default browser in all Mac OS X releases from Mac OS X DP4 up to and including Mac OS X v10.2.
