Editing XQuartz (section)

== History ==

X11.app was initially available as a downloadable public [[Development stage|beta]] for [[Mac OS X v10.2|Mac OS X 10.2 Jaguar]] and later included as a standard package for [[Mac OS X v10.3|Mac OS X 10.3 Panther]]. In [[Mac OS X v10.4|Mac OS X 10.4 Tiger]] X11.app was an optional install included on the install DVD. [[Mac OS X v10.5|Mac OS X 10.5 Leopard]], [[Mac OS X v10.6|Mac OS X 10.6 Snow Leopard]], and [[Mac OS X v10.7|Mac OS X 10.7 Lion]] installed X11.app by default, but from [[OS X Mountain Lion|OS X 10.8 Mountain Lion]] on Apple dropped dedicated support for X11.app, with users being directed to the [[Open-source software|open source]] XQuartz project (to which Apple contributes) instead.<ref name=":0">{{Cite news|url=http://www.macrumors.com/2012/02/17/apple-removes-x11-in-os-x-mountain-lion-shifts-support-to-open-source-xquartz/|title=Apple Removes X11 in OS X 10.8 Mountain Lion, Shifts Support to Open Source XQuartz|access-date=2016-09-14}}</ref>

In [[Mac OS X v10.4|Mac OS X 10.4 Tiger]], Apple's X11 implemented [[X protocol|X11 protocol]] release 6.6 (X11R6.6). This implementation includes an XFree86 4.4 based X11 window server, [[Quartz (graphics layer)|Quartz]] rootless window manager, libraries, and basic utilities such as [[xterm]].<ref>{{Cite web |url=https://developer.apple.com/opensource/tools/X11.html |title=XQuartz |date=2016-10-21 |archive-url=https://web.archive.org/web/20161021001147/https://developer.apple.com/opensource/tools/X11.html |archive-date=21 October 2016 |url-status=dead}}</ref> "Rootless" means that X window applications show up on the Quartz desktop, appearing like any other windowed Quartz application (that is, not in a virtual desktop contained within another window). In [[Mac OS X v10.5|Mac OS X Leopard]], X11 was updated to use [[X.Org Server]] (X11R7.2) rather than [[XFree86]].<ref>{{Cite web|url=https://www.macworld.com/article/1060811/leopard_terminal_x11.html?page=2|title=Inside Leopard: Under-the-hood, Page 2|date=2007-11-02|access-date=2020-06-30|website=[[Macworld]]}}</ref> The source code for X11 is available from Apple.
