Mac OS X v10.2

Mac OS X Jaguar (version 10.2) is the third major release of macOS, Apple's desktop and server operating system. It superseded Mac OS X 10.1 and preceded Mac OS X Panther. The operating system was released on August 23, 2002 either for single-computer installations, and in a "family pack," which allowed five installations on separate computers in one household. Jaguar was the first Mac OS X release to publicly use its code name in marketing and advertisements. Mac OS X Jaguar required a PowerPC G3 or G4 CPU and 128 MB of RAM. Special builds were released for the first PowerPC G5 systems released by Apple. Jaguar introduced many new features to Mac OS X, which are still supported to this day, including MPEG-4 support in QuickTime, Address Book, and Inkwell for handwriting recognition. It also included the first release of Apple's Zeroconf implementation, Rendezvous (later renamed to Bonjour), which allows devices on the same network to automatically discover each other and offer available services, such as , , and printers, to the user. Mac OS X Jaguar Server 10.2.2 added to HFS Plus, the native Macintosh file system, to add increased reliability and data recovery features. This was later added to the standard Mac OS X in version 10.3 Panther. Jaguar saw the debut of Quartz Extreme, a technology used to composite graphics directly on the video card, without the use of software to composite windows. The technology allotted the task of drawing the 3D surface of windows to the video card, rather than to the CPU, to increase interface responsiveness and performance. Universal Access was added to allow the Macintosh to be usable by disabled computer users. The user interface of Jaguar was also amended to add search features to the Finder using the updated Sherlock 3. Internally, Jaguar also added the Common Unix Printing System (also known as CUPS), a modular printing system for Unix-like operating systems, and improved support for Microsoft Windows networks using the open-source Samba as a server for the SMB remote file access protocol and a FreeBSD-derived module as a client for SMB.
