Hi Saleem, in my own experience with the yosemite update, after the update, i have had to do that :
1) Xcode via apple store (itunes) you have to create or use you apple ID etc... 2) Install XQuartz : http://xquartz.macosforge.org/downloads/SL/XQuartz-2.7.7.dmg 3) Install ccp4 : http://www.ccp4.ac.uk/download/index.php#os=mac In my case it was sufficient for ccp4, ADXV and some other.

Since then I am unable to open CCP4. I have tried to reinstall the CCP4 but still the problem is there. Anyone have any information how to fix this issue. I have attached the screen shot of error message. regards Saleem
