MacOS Support?

Hello all, I followed the instructions for building Octopus on MacOS Sierra here: https://octopus-code.org/wiki/Compiling_octopus_in_OS_X with the necessary substitutions to compile against Homebrew's gcc, and have run into some issues; this isn't blocking my work right now, but it would be nice to be able to prototype things locally. Is MacOS "officially" a supported configuration (in which case I would be happy to give more details in this report and help debug) or is it not a priority? As an aside, I also created configurations to build Octopus on Gitlab CI and Travis (on which the above error can be reproduced) in case they would be useful.
