XQuartz 2.8.0 was released for macOS 10.9 or later a couple of weeks ago.
I've now upgraded two machines (one Big Sur the other Catalina) and so far I've not had any issues.
This release also supports Apple Silicon.
How To Use Xquartz
XQuartz 2.8.0 has been released for macOS 10.9 or later. I've been in touch with a couple of users and they report no issues so far. This is the first version with Apple Silicon support.
The XQuartz project is an open-source effort to develop a version of the X.Org X Window System that runs on OS X. Together with supporting libraries and applications, it forms the X11.app that Apple shipped with OS X versions 10.5 through 10.7.
Changes in 2.8.0
- Adds native support for Apple Silicon Macs.
- Removes support for versions of macOS older than 10.9
- Uses system libXplugin
- Removes build-time support for deprecated X11 libraries:
- Removes deprecated commands:
- Removes xpyb
- Removes older libpng

- XQuartz became the default X11 implementation for many OS X users after the 10.8 iteration, when Apple decided to completely remove the X11 server and client libraries from the default OS X installation. Moreover, XQuartz is an Apple and community supported project, designed to keep improving support for X11 apps on the OS X platform.
The plugin runs local copies of several executable programs from the Richardson Lab at Duke University, authors of the MolProbity software, parses the output, and displays the results in the PyMOL viewport. There are both a graphical user interface (GUI) for general point-and-click use, and a command-line interface (CLI) suitable for scripting.

The Reduce, Probe, and Prekin executables are only available for Linux and MacOS, PYMOL is available from Schrödinger and also available via Homebrew, you will need to install XQuartz first.
There are detailed instructions on how to install a variety of chemistry/cheminfomatics/biology packages on a Mac here.
Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO 4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. This directory contains binaries for a base distribution and packages to run on Mac OS X (release 10.6 and above). Mac OS 8.6 to 9.2 (and Mac OS X 10.1) are no longer supported but you can find the last supported release of R for these systems (which is R 1.7.1) here.
XQuartz 2.7.11 is available for download.

- Fix font caching (#97546)
- Plug a memory leak
- Plus fixes for a memory leak and improved error handling
Xquartz Keeps Opening

An update from X11.org

Hello, I recently heard on the Apple x11-users mailing list that remote OpenGLrendering (IGLX) is being phased out of XOrg and not being replaced. Isthis really the case or am I misunderstanding?
You have heard incorrectly. It is disabled by default for securityreasons, as it's been a repeated source of exploitable bugs, but thefeature itself isn't going away.
One caveat is there's no easy way to enable it other than the commandline, and not all display managers give you a mechanism to pass arbitraryoptions in (which is reasonable enough). I've added an xorg.conf option toenable IGLX in master, and I'll be backporting that to the various stablebranches as well.
There is an important discussion taking place on the X11 users list regarding the support of indirect GLX (iGLX) in XQuartz.
Indirect GLX is an extension offered by X11 that enables the transmission of OpenGL commands from an X11 client on a remote machine to an X11 server on your desktop over the network. For example, when your OpenGL science application running on a remote host tries to draw images using OpenGL and display on your local XOrg (XQuartz) desktop, IGLX (red line below) is used to send the commands to your local X server, which then uses OpenGL locally to draw the commands.
In seems in the latest version of XQuartz (2.7.9) this is turned off by default and there appears to be a move to deprecate this protocol. This seems to have been prompted by security concerns but I know nothing of the details. Zotero tutorial.
However many scientific applications use this capability and it seems there is no alternative. If this is likely to be an issue for you I suggest you subscribe to the X11 list and make your views known.
