There is an issue with indirect (remote) rendering of GLX. It was
disabled in the most recent Xserver release by default.
I had to go through a bunch of painful hoops before I figured out how to
get it re-enabled on RHEL (6 and then differently for 7).
I don't know if it's your Linux box, or something in Xquartz is doing
(which also messed up its flat_namespace flag for libXt this most recent
release, which broke all Motif compiles...even though Xt is pretty much
only used for Motif these days, if at all).
Seems like there a general disregard for traditional use-cases (i.e.
legacy Unix) support in the latest group-think among developers.
If you need instruction for the RHEL fix(es), I can post them.

Hello
I have installed Quartz on my Mac. I use it to run graphics from remote linux
machine. So far Xeyes, edit… seem to work but when I run VMD, that requires
OpenGL it failes with “Unable to create OpenGL window”
I guess I may need to change some settings? Could anyone advise please?
Thanks

This was covered extensively on the mailing list back in May. XQuartz
2.7.9 ships with OpenGL disabled by default and with no easy way to enable
it. (Except by editing one of the startup scripts)
Bug 96260
<https://bugs.freedesktop.org/show_bug.cgi?id=96260>
covers this. This bug should be fixed in the latest 2.7.10 release
candidates, and an attachment to Bug 96260 also contains a patch that can
be applied to XQuartz 2.7.9 that will allow you to re-enable OpenGL
support in 2.7.9 by giving the
defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
command after the patch has been applied.
