Well, not one person makes an OS. :) Steve Jobs left Apple many years ago (at about 1989 maybe, google is your friend if you want to know :) and created NeXT. NeXT first built hardware and software. Hardware was the very nice NeXT boxes and cubes. The OS was NEXTSTEP. NEXTSTEP was based on Mach Unix foundation. (Microkernel architecture, unlike Linux) The biggest difference to other UNIX flavours is the fact that NEXTSTEP doesn't have X11 as a graphical environment but 'Display Postscript'. Truely a wonderful system.. :) The other biggest difference (hehee) to other UNIX flavours is the fact that NEXTSTEP provides a complete object-oriented application framework layer. All the things the Java guys do today (like remote method invocation etc etc) are techonogies which are more than 12 years old. :) A bit later NeXT stopped producing hardware and cleaned up the object oriented framework a bit, and renamed it to 'OpenStep'. OpenStep was available for 4 platforms: NeXT, Sparc, HP and.. sheesh.. Intel. :p Meanwhile Apple was not that successful and they needed a new CEO, so they bought NeXT. (which was probably the best thing that could have happened to NeXT - at least their technology was not 'lost') Apple needed longer than expected to adopt NeXT's technology in the new operating system and changed the general direction more than once. (one direction was Rhapsody on their way) Finally they had something: OSX! :) All the OSX community needs now is a commercial chess engine. :) >ps, what program can read postscipt file under windows? Get a NEXTSTEP machine and send the PS file to the window server. HTH! :) Sargon
