Dear Freesurfers, i am a brand new user of a Mac Pro without any experience of that system. I am trying to include in the bash file the startup commands for Freesurfer, but i could find a way to save the changes in the bash file. I already tried to change the permission status of the bashrc file with chmod +w bashrc, but it is not possible, just says "Operation not permitted". Could somebody help me with this? Thanks a lot, Cheers, Thomas
