Mac OS X 10.0


 * See also: Mac OS X 10.0.0



Mac OS X 10.0, code-named Cheetah, is the first official release of Apple Inc.'s operating system Mac OS X after Mac OS X Public Beta and before Mac OS X 10.1.

Features
Mac OS X 10.0, and all updates in the 10.0.x series, lacked in some features (notably DVD support) but was usable and stable. Mac OS X 10.0 contained the following features:


 * The Dock. The Dock was a brand new way to organize OS X's applications.
 * The Mail application. The Mail application is a way to receive and send emails.
 * The Address Book. It is a virtual address book for the Mac.
 * The Aqua interface. It is the visual interface theme of the Mac OS X operating system.
 * AppleScript. It is a scripting language for the Mac.
 * Preview: Support for viewing PDFs.



Other features present in OS 9 but lacking in OS X 10.0 were eventually delivered with successive system updates.

It was priced at $129.

Multilingual snags
With Mac OS X 10.0.0 began a short era (that practically ended with Mac OS X 10.2 Jaguar's release) where Apple offered two types of installation CDs: 1Z and 2Z CDs. The difference in the two lay in the extent of multilingual support.

Input of simplified Chinese, traditional Chinese, and Korean were only included with the 2Z CDs. They also came with more languages (the full set of 15 languages), whereas the 1Z CDs came only with about eight languages and in version 10.0.x, could not actually display simplified Chinese, traditional Chinese and Korean (except for the Chinese characters present in Japanese Kanji).

A variant of 2Z CDs began when Mac OS X 10.0.3 was released to the Asian market. However, it could not be upgraded to version 10.0.4 of the operating system.

The brief period of multilingual unhappiness ended with the release of Mac OS X 10.1, and came to a real end for good with Mac OS X 10.2. Today, all Mac OS X CDs and Mac OS X Macs come preinstalled with the full set of 15 languages and full multilingual compatibility.

Criticism
Mac OS X 10.0 was heavity critizied for of many reasons.
 * Slow response - Mac OS X 10.0's Aqua UI was very slow responding to commands given by the user. Previous OSs by Apple were significantly more responsive.
 * Stability - Mac OS X 10.0 contained a lot of kernel panics, due mostly to minimal hardware support in the kernel drivers.
 * Lack of features - OS X 10.0 lacked features that were standard in Mac OS 9, such as DVD playback and CD burning.
