It included the Terminal, it was a feature that allowed access to Mac OS X's underpinnings, namely the Unix core Mac OS had previously had the distinction of being one of the few operating systems with no command line interface at all. The features of the release include the Dock which was a new way of organizing one's Mac OS X applications on a user interface, and a change from the classic method of Application launching in previous Mac OS systems. Briefly mention the backstory (searching for a replacement for the classic Mac OS), but otherwise mainly focus on details specific to Mac OS X 10.0's development (from Singh 2004 and other sources). This section needs expansion with: For inspiration, see Windows XP#Development. Six months after its release, Mac OS X 10.0 was succeeded by Mac OS X 10.1, code named Puma. This was important for compatibility reasons while many Mac OS 9 applications could be run under Mac OS X in the Classic environment, some, such as applications that directly accessed hardware, could only run under Mac OS 9. The core components of Mac OS X were open sourced as Darwin.īoxed releases of Mac OS X 10.0 also included a copy of Mac OS 9.1, which can be installed alongside with Mac OS X 10.0, through the means of dual booting (which meant that reboots are required for switching between the two OSes). Many technologies were ported from the classic Mac OS, including Sherlock and the QuickTime framework.

It introduced the Quartz graphics rendering engine for hardware-accelerated animations. It was derived from NeXTSTEP and FreeBSD, and featured a new user interface called Aqua, as well as improved stability and security due to its new Unix foundations. Mac OS X was Apple's long-awaited successor to the classic Mac OS. It was released on March 24, 2001, for a price of $129 after a public beta. Mac OS X 10.0 ( code named Cheetah) is the first major release of Mac OS X, Apple's desktop and server operating system.
