Ten years ago today Apple released the first desktop version of its renowned operating system Mac OS X. Mac OS X 10.0 was the first Mac operating system named after a big cat (Cheetah) and it brought many changes to Apple computers.
Unlike the desktop OS used by Apple until that moment – versions 9 and earlier – Mac OS X is a Unix-like operating system based entirely on the OpenStep technology developed by NeXT, the computer company founded by Steve Jobs after he was forced to resign from Apple. Mac OS X had a completely new codebase, design, file system and hardware support.
After version 10.0 launched in March 24th 2001, succeeding releases of Apple’s operating system continued with the original cat-based naming pattern: Puma, Jaguar, Panther, Tiger, Leopard, Snow Leopard and soon, Lion.
Happy birthday, OS X!
