They released Mac OS X Server in 1999, followed a year later by the almost unrecognisable OS X Public Beta.Ĭheck out these screenshots, which (in order from top to bottom) show the gradual progression from NeXTstep's multi-column Browser to Mac OS X 10.3's Finder*.Īccording to the license you cant run the OS on an emulator because its not 'Apple hardware'.

About a year later Apple announced the name change from Rhapsody to Mac OS X. Steve Jobs became Interim CEO after Amelio's departure in 1997 and killed the cross platform versions of Rhapsody along with the Mac 'clone' industry. There was no equivalent to the Carbon frameworks in those early days, which was the subject of much debate. At that stage, the name for Cocoa was YellowBox, and the Classic environment was called BlueBox IIRC. Apple also had a version of the Rhapsody frameworks that ran in NT, which they inherited from NeXT. Rhapsody was the name of the OS developed under the leadership of Gil Amelio, it was heavily based on OpenStep (moreso than OS X), hence it's cross platform capabilities. There have been numerous aborted attempts at creating a next generation Mac OS under a variety of strange code names like Pink, Taligent and Copland.
