Mac OS X Panther, Version 10.3, was the fourth major release of the Mac OS X [ten] operating system, and the second to be referred to by its codename, “Panther,” in its product marketing. Previous versions were codenamed “Cheetah” (Version 10.0) and “Puma” (Version 10.1), but they were referred to only by their version numbers. Version 10.2 was publicly announced as “Jaguar,” and this version, 10.3, continued the “big cat” codenames with “Panther.”
According to Apple, “Panther delivers more than 150 breakthrough new features including a completely new Finder that provides one-click access to a user’s favorite files and folders; Exposé, a revolutionary new way to instantly see all open windows at once; and iChat AV, a complete desktop video conferencing solution for business, education and consumers.”
This set includes all installer CDs and a set of three 7.5 x 9-inch booklets, including installation directions, the software license, and a “Welcome to Panther” booklet describing the operating system’s main features. The set is packaged in a 8.25 x 9.25-inch clear plastic envelope.
When it was released on October 24, 2003, this Mac OS X upgrade cost US$129.
