Hello, I am having some issues with the Athena software. After upgrading the OS of the macbook pro to "El Capitan" Version 10.11.3, Athena stopped working properly. Once the iXAFS icon was clicked nothing happened. I decided to do a bit of research and installed the latest verion of XQuartz version 2.7.8. I was able to launch athena by executting "athena" from the terminal. Up to that point, I figured that everything was running smoothly until I realized that I could prompt any plots. Something in the software or operating system was not allowing Athena to display plots. I would be really grateful if you could provide me with a solution to this problem (if there is any) or any advice that would allow me to process XAS data again. Thank you Regards, Manuel Cossio
