External Email - Use Caution        

I would downloaded and install the latest Xquartz (X-Windows for MacOS) which is version 2.8.3 from MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.xquartz.org/   This was updated only a week ago and contains universal binaries.

After you install Xquartz open a new terminal window and type “glxgears”.  An X-Window should pop up showing the spinning gears.

% which glxgears
/opt/X11/bin/glxgears
% glxgears
303 frames in 5.0 seconds = 60.564 FPS
309 frames in 5.0 seconds = 61.607 FPS
..
.
… close glxgears window to exit ....

Then at least your X-Windows graphics will be up to date (which might affect the GUI).  Then try your image again.

Do you see any warnings, error, info, etc., listed in the terminal window after the freeview command?   If so, please send that along.

Maybe you could send along a screenshot of what “about this mac” displays.  That would tell us if you are using a graphics card or the built-in graphics - and also a screenshot of the freeview window.
