May 02, 2017 About X11 for Mac. X11 is no longer included with Mac, but X11 server and client libraries are available from the XQuartz project. Apple created the XQuartz project as a community effort to further develop and support X11 on Mac. The XQuartz project was originally based on the version of X11 included in Mac OS X v10.5. Apr 15, 2017 X11 is an optional install on the Leopard install DVD. Using X11 in Mac OS X. EDIT: From: 'The X11 SDK headers are available as part of the Xcode Developer Tools.' Hope this helps.
I use it often to view the preferences for the apps I have installed on my Mac. This is a folder that Apple feels you shouldn’t need access to most of the the time, but occasionally, you may need it for specific things.

Export itunes library from mac to pc. XQuartz is an open-source version of the X.Org X server, a component of the X Window System (X11, or shortened to simply X, and sometimes informally X-Windows) that runs on macOS.[1] It formally replaced Apple's internal X11 app. The name 'XQuartz' derives from Quartz, part of the macOS Core Graphics framework, to which XQuartz connects these applications. XQuartz allows cross-platform applications using X11 for the GUI to run on macOS, many of which are not specifically designed for macOS. This includes numerous scientific and academic software projects.[2]
History[edit]
X11.app was initially available as a downloadable public beta for Mac OS X 10.2 Jaguar and later included as a standard package for Mac OS X 10.3 Panther. In Mac OS X 10.4 Tiger X11.app was an optional install included on the install DVD. Mac OS X 10.5 Leopard, Mac OS X 10.6 Snow Leopard, and Mac OS X 10.7 Lion installed X11.app by default, but from OS X 10.8 Mountain Lion on Apple dropped dedicated support for X11.app, with users being directed to the open source XQuartz project (to which Apple contributes) instead.[2]
In Mac OS X 10.4 Tiger, Apple's X11 implemented X11 protocol release 6.6 (X11R6.6). This implementation includes an XFree86 4.4 based X11 window server, Quartz rootless window manager, libraries, and basic utilities such as xterm.[3] '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 Leopard, X11 was updated to use X.Org Server (X11R7.2) rather than XFree86.[4] The source code for X11 is available from Apple. Some source code is available under the Apple Public Source License while the bulk is licensed under the MIT License.
Current version[edit]
The current version of XQuartz is a DDX (Device Dependent X[5]) included in the X.Org Server and implements support for hardware-accelerated 2D graphics (in versions prior to 2.1), hardware OpenGL acceleration and integration with Aqua, the macOS graphical user interface (GUI). As of version 2.7.11, XQuartz does not provide support for high-resolution Retina displays to X11 apps, which run in pixel-doubled mode on high-resolution displays.

Apple created the XQuartz project as a community effort to further develop and support X11 on Mac. The XQuartz project was originally based on the version of X11 included in Mac OS X v10.5. There have since been multiple releases of XQuartz with fixes, support for new features, and additional refinements to the X11 experience. Apple is a contributor to the XQuartz project and has worked to ensure that X11 works as expected with macOS and latest available versions of XQuartz.
