Version 10.2, code-named Jaguar, was released on August 23, 2002. It was the first truly mature version of Mac OS X, and it was subsequently at this time that users seriously began the migration from Mac OS to Mac OS X. Mac OS, ending with 9.2.2, was dead, as it turned out that no more resources were to be dedicated to the development of this operating system. Mac OS X 10.2 was fast, had a pleasant user interface, and many so-called killer applications (key software packages ported from Mac OS) were available at this time.
The following product description seen at various sellers lists the main features in 10.2:
Referred to by its code name, Jaguar, Mac OS X 10.2 contains more than 150 new features and provides significant enhancements to its modern, Unix-based foundation. From AOL-compatible instant messaging to advanced junk mail filtering and a revolutionary Web search tool, Jaguar is as innovative as the computers that run it.
With iChat, the AOL-compatible instant messenger, you can chat with your AOL and Mac.com buddies through a fun, easy-to-use interface. Sherlock 3, the new Web search tool, delivers stock quotes, maps, restaurants, and more without a browser. QuickTime 6 supports MPEG-4, the new worldwide standard for playing and viewing pro-quality audio and video over the Internet. This new version also includes Rendezvous, a revolutionary networking technology that lets you link computers and devices instantly without any configuration.
Another cool new feature is Inkwell, which lets you write on a graphics tablet, and Jaguar turns your handwriting into typed text at the cursor in any application. And with new compatibility built into Mac OS X 10.2, sharing files, using Windows documents, and connecting to a Windows network have never been easier. And it easily runs Microsoft Office. For business users, Jaguar comes with Active Directory interoperability, and with a PPTP-based VPN (virtual private network) client that allows Mac users to connect remotely to Windows corporate networks.
Jaguar's complete suite of professional-quality developer tools now features GCC 3.1, which radically improves C++ build times and standards compliance. The updated Interface Builder makes it easier to group, lock, and drag Aqua controls between windows for rapid user-interface creation. And, perhaps best of all, these professional tools are still included with every copy of Jaguar, empowering Java, C, and AppleScript Studio developers to do their best work on the Macintosh platform.
Version 10.3, code-named Panther, was released on October 25, 2003. Panther took Mac OS X a solid step farther than Jaguar by optimizing many operations under the hood and by offering many visible enhancements and features.
