Yes. Things are now fine using 2.7.11. I just had to play a bit with the Apple Thunderbolt Display which was causing XQuartz to behave funny. Problem solved.

We did not have to downgrade to 2.7.8. CCP4i and Coot works perfectly fine with XQuartz 2.7.11 on multiple iMacs and MacBook Pros we have in the lab.

This was the last version where Xquartz behaved properly and it runs fine on High Sierra.

Essentially, X11 does not seem to understand touchpad actions (for example cannot close X11 windows, cannot drag them around, etc.). This problems also affects programs that rely on X11. Has anyone experienced (and ideally solved) this problem? Thanks in advance Roberto Roberto A.
