Marketing
In October 2002, Apple offered free copies of Jaguar to all U.S K-12 teachers in the "X For Teachers" program. Teachers who wanted a copy simply had to fill out a form and a packet containing Mac OS X discs and manuals was shipped to the school where they worked.
Jaguar marked the first Mac OS X release which publicly used its code name as both a marketing ploy and as an official reference to the operating system. To that effect, Apple replaced their standard Mac OS X box with a new Jaguar-themed box.
Mac OS X v10.2 was never officially referred to as Jaguar in the United Kingdom due to an agreement with the car manufacturer Jaguar, although boxes and CDs still bore the Jaguar-fur logo.
Today, all Mac OS X releases are given a feline-related name upon announcement, and Mac OS X releases are now referred to by their code name, in addition to version numbers.
