Xcode
I have been running Fortran programs for many years. Now when I try to open a Fortran program I get a message telling me that I have to install supplementary Xcode software. When I hit the Install button in the window containing the message I, the installation process is interrupted by a second message informing me that an error of unknown origin has occurred. What has changed? How do I restore capability to run Fortran programs on my Mac?
