History: The codename of this version of Mac OS X became publicly known long before the release of 10.2 and therefore Apple decided to officially refer to this version of Mac OS X as Jaguar. Jaguar improved the performance of Mac OS X by featuring Quartz Extreme, a new version of Quartz that took advantage of the graphics accelerator cards on the modern Macs. The Mail application now had a built-in Spam mail filter, which was considered to be one of the best available. Furthermore, Apple added handwriting recognition called Inkwell. Inkwell was based on Apple's Newton handwriting recognition. New applications were also introduced such as iChat, QuickTime 6 and Sherlock 3 (and also adding a classic-Mac OS-like quick search to the Finder). Apple also added Bluetooth support and introduced Rendezvous. Another feature that was included on the demand of the users were the spring-loading folders which were available under Mac OS 9, but were missing in the first two releases of Mac OS X. Jaguar was sold for $129 U.S.
