Apple released OS X in March, amid considerable hype and speculation. Built on an entirely new software base, the Unix-based OS X was considered the most important upgrade of the Mac operating system since the first version came out in 1984.
The initial OS X release attracted some criticism, however, for lacking key technologies, such as support for CD burners and DVD playback.
Those functions and numerous others were included when Apple released in October the first major update to the software: OS X version 10.1. The update boosted consumer confidence in the OS and prompted major software developers to show increased interest in creating OS X applications.
The release turned somewhat sour for Apple, however, when some Mac enthusiasts found a way to convert the free upgrade into a full version of the operating system.
