Jaguar

Mac OS X version 10.2 Jaguar is the third major release of Mac OS X, Apple's desktop and server operating system. The operating system was generally well received by most Mac users as a large step forward in the areas of stability, general speed enhancements, compatibility with other flavors of Unix and the lineup of both graphical and terminal applications available; however, many critics still claimed that significant user interface speed issues existed and that the operating system was still a big step down from Mac OS 9. Jaguar was the first Mac OS X release to publicly use its code name in marketing and advertisements, a practice that has continued in subsequent releases of the operating system.
