I have recently upgraded my mac to run the new OS X Mountain Lion and in the process noticed that apple no longer supports or includes X11. They instead have moved to XQuartz
http://xquartz.macosforge.org. I downloaded the new XQuartz to my computer and obviously still cannot access iXAFS. I was wondering if someone could offer some advice for me so that I can still run iXAFS on my macbook (Macbook pro OS X version 10.8, 2.3 GHz intel core i5).
