remote = False not working on Mac

I was trying to run on my mac remote = False and was receiving this error. I installed gfortran as it seemed like that may have been the problem but was still getting this error. gcc is installed but redirects to clang. Any suggestions?

Does this solution work? https://stackoverflow.com/questions/57207357/dyld-library-not-loaded-usr-local-gfortran-lib-libgfortran-3-dylib-reason-im

What is your MacOS version? You may need gcc in addition to gfortran.

I am running macOS Mojave version 10.14.6

Yes! That helped solve the problem. MacOS defaults to clang and so I had to brew install gcc to get around it. Unfortunately I am now running into

Try installing gfortran with brew as well: brew install gfortran

The issue for me was having gcc 8 installed instead of gcc 9. Using brew install gcc worked for me. This should install gfortran as well, though if you already have it installed you might need to run rm /usr/local/bin/gfortran and then brew link gcc so everything works correctly.

Maybe it's worth adding these instructions to the installation docs?

I probably just need to link any dependencies in the executable so there isn't a dependency on gfortran shared libraries. I'll try to link the .a (static) libraries on the next release. It will make the apm_mac executable larger but it will hopefully eliminate this extra step.

Added gcc 9+ dependency information to the documentation.
