The Mac OS X Public Beta (internally codenamed "Kodiak") was an early beta version of Apple Computer's Mac OS X operating system Cheetah. It was released to the public on September 13, 2000 for US$29.95. It allowed software developers and early adopters to test a preview of the upcoming operating system and develop software for the forthcoming operating system before its final release. The US version had a build number of 1H39 and the international version had build number 2E14.
The Public Beta succeeded Mac OS X Server 1.0, the first public release of Apple's new NeXT OpenStep-based operating system, which used a variant of the classic Mac OS' "Platinum" user interface look and feel. The Public Beta introduced the Aqua user interface to the world. Fundamental user interface changes were revealed with respect to fonts, the Dock, the menu bar (with an Apple logo at the center which was later repositioned to the left of the menu bar and made an active interface element). System icons were much larger and more detailed, and new interface eye candy was prevalent.
With the Mac OS X Public Beta came fundamental technical changes, most courtesy of an open source Darwin 1.2.1 core, including two features that Mac users and developers had been anticipating for almost a decade: preemptive multitasking and protected memory. To illustrate the benefits of the latter, at the MacWorld Expo in June 2000, Apple CEO Steve Jobs demonstrated Bomb.app, a test application intended to crash.
The Public Beta included many of the standard apps bundled with Mac OS X today, such as TextEdit, Preview, Mail, Quicktime Player and Terminal. Also included with the Public Beta, but not in any subsequent versions of Mac OS X were a simple MP3 player (iTunes had not yet been introduced), Sketch, a basic vector drawing program demonstrating features of Quartz, and HTMLEdit, a WYSIWYG HTML editor inherited from WebObjects.
Native shrinkware applications were few and far between. Early adopters had to turn to open source or shareware alternatives, giving rise to an active homebrew software community around the new operating system. Many programs in use on early Mac OS X systems were inherited from OPENSTEP or Rhapsody developer releases (e.g. OmniWeb or Fire), or were simple wrapper apps that provided a graphical interface to a command-line Unix program.
Mac OS X Public Beta expired in Spring 2001. It will not run on current Macintosh hardware, which uses the x86 processor architecture, nor on later Power PC-based Macintosh computers. Using the Mac OS X Public Beta on compatible equipment today requires setting the hardware clock to a date prior to May 2001.
Only the Aqua GUI and related components of the Public Beta were subject to expiry. The underlying Darwin command-line based OS continued to function.
Mac OS X v10.0 was the first completed release of Mac OS X. It became available in March 2001. Owners of the Public Beta version were entitled to a $30 discount on the price of the first full version of Mac OS X 10.0.
