Universal Access was added to allow the Macintosh to be usable by disabled computer users. 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. 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. This was later added to the standard Mac OS X in version 10.3 Panther. Mac OS X Jaguar Server 10.2.2 added journaling to HFS Plus, the native Macintosh file system, to add increased reliability and data recovery features. 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 file sharing, shared scanners, and printers, to the user.

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. Special builds were released for the first PowerPC G5 systems released by Apple. Mac OS X Jaguar required a PowerPC G3 or G4 CPU and 128 MB of RAM. Jaguar was the first Mac OS X release to publicly use its code name in marketing and advertisements. The operating system was released on Augeither for single-computer installations, and in a 'family pack', which allowed five installations on separate computers in one household.

It superseded Mac OS X 10.1 and preceded Mac OS X Panther. The kernel supports the important file systems (ext2/ext3/ext4, ReiserFS, Reiser4, Btrfs, XFS, JFS, VFAT, NTFS, iso9660), as well as network file systems (Samba and NFS).Mac OS X Jaguar (version 10.2) is the third major release of macOS, Apple's desktop and server operating system.

It can be used on Linux servers, Linux desktops, or Windows boxes. It comes with many Linux software such as system tools (parted, partimage, fstools, etc.) and basic tools (editors, Midnight Commander, network tools, etc.). It provides you with an easy way to carry out admin tasks on your computer, such as creating and editing the hard disk partitions. SystemRescueCd is a Linux system rescue disk available as a bootable CD-ROM or USB stick to administrate or repair your system and data after a crash.
