Mac OS X 10.0 was a radical departure from the previous "classic" Macintosh operating system. Mac OS X was Apple's answer to the long awaited call for a next generation Macintosh operating system. Mac OS X 10.0 introduced a brand new code base, completely separate from Mac OS 9's code base, and all other previous Apple operating systems. Mac OS X introduced a new Darwin Unix-like core, as well as introducing a totally new system of memory management. Mac OS X is widely regarded to be the best operating system Apple has ever produced; however, Mac OS X 10.0 was a rocky start to the Mac OS X line, plagued with missing features and performance issues -- although it was praised for being a good start to a brand new operating system in terms of completeness and overall operating system stability.

System Requirements

The System Requirements for Mac OS X 10.0 were not well received by the Macintosh community, as at the time the amount of RAM standard with Macintosh computers was 64 megabytes of RAM, while the Mac OS X 10.0 requirements called for 128 megabytes of RAM. As well, processor upgrade cards, which were quite popular for obsolete Power Mac G3 computers, were not supported (and never officially have been, but can be made to work through third-party utility programs).

Limitations

• File-Sharing as a client. The System can only use TCP/IP ^[1] , not AppleTalk, to connect to servers sharing the Apple Filing Protocol. The System cannot use smb to connect to Windows or Samba servers.

• File-Sharing as a server. As a server, the system is set up to share only the afp (over TCP/IP), http, ssh and ftp protocols.

• Shortage of Native Applications. While the System can run Classic Mac applications (in the Classic environment), and has some support for Java applications and ported UNIX applications, there are few if any native Mac OS X applications available for this version of Mac OS X. Most applications for Cheetah were ported using the Carbon libraries.

The Apple Filing Protocol (AFP) is a layer 6 (presentation layer) network protocol that offers file services for Mac OS X and Classic Mac OS. In Mac OS X, AFP is one of several file services supported including Server Message Block (SMB), Network File System (NFS), File Transfer Protocol (FTP...

Criticisms

While the first Mac OS X release was a great operating system in terms of its technical underpinnings, and in relation to its brand new code-base, Mac OS X 10.0 was heavily criticized. There were three main reasons for criticism:

• Interface Responsiveness - The brand-new Aqua interface was sluggish at best. It was heavily criticized for its slow application launch speed and user interface response speed. The interface response times compared to earlier Apple operating systems showed that Mac OS X still had a long way to go in terms of interface design.
• Stability - While 'theoretical' stability in Mac OS X was much better than stability in Mac OS 9, Mac OS X 10.0 was riddled with fatal bugs that caused kernel panics, especially in complex hardware setups.
• Missing Features and Hardware Compatibility Issues - Another reason for criticism were the missing features most especially DVD playback, as well as CD burning, both of which were still available in OS 9. There were also several issues in respect to missing printer drivers and other hardware drivers.

Supersession / Succession

The heavy criticism of Mac OS X 10.0 ultimately resulted in Apple offering a free upgrade to Mac OS X v10.1 to all Mac OS X 10.0 users. Mac OS X version 10. ...

Multilingual snags

With Mac OS X version 10.0.0 began a short era (that ended with Mac OS X version 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 v10.0.3 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 confusion ended with the release of Mac OS X v10.1, and came to a real end for good with Mac OS X v10.2. Currently, all Mac OS X installer CDs and preinstallations include the full set of 15 languages and full multilingual compatibility.
