Apple releases Mac OS X 10.2, code-named Jaguar. For the first time, the “Happy Mac” icon is not part of a Mac operating system’s startup process, replaced instead by the gray Apple logo that is still in use today. Jaguar was also the first Mac operating system where Apple publicly used the code name to reference the operating system and for marketing purposes. All Mac OS releases since Jaguar have been referred to by its big cat-themed code name.

From my perspective, Mac OS X 10.2 was the first Mac OS X release that was truly usable. The previous releases (10.0 and 10.1) felt more like transitional stages from Mac OS 9. But Jaguar tied up a lot of loose ends from a usability standpoint and introduced many of the underlying technologies that are now standard parts of modern Mac operating systems.
