Editing Mac OS X Public Beta (section)

==Expiration==
The Mac OS X Public Beta expired on May 14, 2001; approximately two months after the release of [[Mac OS X 10.0]], the completed version of the operating system released in March 2001.<ref>{{cite web|url=http://www.macobserver.com/tmo/article/Mac_OS_X_Public_Beta_Expires_Today|title=Mac OS X Public Beta Expires Today|access-date=March 4, 2015|archive-date=January 15, 2015|archive-url=https://web.archive.org/web/20150115011114/http://www.macobserver.com/tmo/article/Mac_OS_X_Public_Beta_Expires_Today|url-status=live}}</ref> As a result, it will not run on later [[PowerPC]]-based Macintosh computers released after early 2001, nor on current Macintosh hardware, which uses the [[x86]] or [[ARM64]] processor architectures. Using the Mac OS X Public Beta on compatible equipment today requires setting the hardware clock to a date prior to the expiration date.

The expiration date forced users to purchase a copy of the final release rather than continuing to use the Public Beta, as well as reassured industry observers skeptical after the Copland and Rhapsody failures that Apple would actually release a next-generation operating system this time. 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.<ref>{{cite web|url=http://www.macworld.com/article/154036/2010/09/osxorigins.html|title=Looking back at OS X's origins|date=September 13, 2010|first=Benj|last=Edwards|work=[[Macworld]]|access-date=September 29, 2011|archive-date=November 18, 2012|archive-url=https://web.archive.org/web/20121118024028/http://www.macworld.com/article/1154036/osxorigins.html|url-status=live}}</ref> 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.<ref>{{cite web|url=http://www.giac.org/paper/gcfa/19/analysis-unknown-mac-os-public-beta-system-mac-os-102/102125|title=Analysis unknown Mac OS Public Beta system|access-date=September 12, 2014|archive-date=September 12, 2014|archive-url=https://web.archive.org/web/20140912205559/http://www.giac.org/paper/gcfa/19/analysis-unknown-mac-os-public-beta-system-mac-os-102/102125|url-status=live}}</ref>
