2001 – Apple released the Mac OS X Server, based on Rhapsody, which was a hybrid of NeXT OPENSTEP. The server ran file services, Macintosh Manager, Quicktime Streaming Server, WebObjects, NetBoot and more.
Each new version of OS X Server then coincided with the desktop release name – Jaguar, Panther, Leopard, etc.
“Built on Mac OS X’s incredibly stable and robust foundation, Mac OS X Server has the power of UNIX, yet is simple and easy to install, administer and maintain,” said Philip Schiller, Apple’s vice president of Worldwide Product Marketing. “Mac OS X Server is Apple’s most powerful server ever and can easily integrate into Mac, Windows and UNIX networks.”
