It is recommended to install and manage the additional compilers and
utilities needed for building and running MOLPRO using the
Homebrew system. Visit
and copy the installation command into a terminal window. On an empty
system, you will be prompted to install command line tools; do this
first. Then accept all prompts from the Homebrew installation script.
The following will install all utilities that might be needed for building and
running MOLPRO for development in serial; for production
calculations in parallel, a binary can be downloaded.
brew install Caskroom/cask/xquartz homebrew/x11/grace \
