Hi Logan, Thanks for this useful information. Didn't know it was possible to rejig binaries in that way! I'm taking the liberty of cc:ing your answer to the list. I forgot to say that this problem affected both the CCP4-distributed Coot and an old stand-alone from Bill Scott that I had in /Library/Coot/bin. It seems from your experience that it doesn't affect the latest compiled versions from Bill. Regarding the contents of /opt/X11/lib, I have:
lrwxr-xr-x 1 root wheel 26 Sep 27 17:19 /opt/X11/lib/libXt.6.dylib -> /opt/X11/lib/libXt.7.dylib -rwxr-xr-x 1 root wheel 698896 Sep 27 07:45 /opt/X11/lib/libXt.7.dylib lrwxr-xr-x 1 501 wheel 13 Sep 27 10:43 /opt/X11/lib/libXt.dylib -> libXt.7.dylib -rwxr-xr-x 1 root wheel 71104 Sep 27 07:45 /opt/X11/lib/libXtst.6.dylib lrwxr-xr-x 1 501 wheel 15 Sep 27 10:43 /opt/X11/lib/libXtst.dylib -> libXtst.6.dylib where the first line is the link I made myself. So libXt.6.dylib seems to have been removed in the latest release. /Derek On 28 Sep 2016, at 13:16, Logan Donaldson <logan.donald...@icloud.com<mailto:logan.donald...@icloud.com>> wrote: I’m running 10.12.1b2 but not the newest X11 yet.
