Mac OS X Jaguar, or Mac OS X 10.2, is the third major release of Mac OS X, Apple’s desktop and server operating system. It superseded Mac OSX Puma and preceded Mac OS X Panther. The operating system was initially available on 23 August 2002 either for single-computer installations, and in a “family pack”, which allowed five installations on separate computers in one household. Most builds of Jaguar were compiled for PPC (for public use) and x86 (for testing purposes for the upcoming partnership with Intel, which would continue until the announcement in 2005). Excellent vintage operating system works like a charm on most PowerPC powered Apple computers since its launch in 2003.
