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 Computer'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 (noticeably those related with DVDs) but was usable and stable. It featured the Aqua interface, the Dock, and everything else that started Mac OS X from the very beginning.

Lacked features were eventually delivered with successive system updates.

It was priced at USD 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.
