    A usable mcs should be in /Applications/Unity/Unity.app/Contents/Frameworks/MonoBleedingEdge/bin/.

    It'll be easiest to add this dir to your $PATH, paste this in the terminal that you want to use (or to your startup scripts).

    PATH=$PATH:/Applications/Unity/Unity.app/Contents/Frameworks/MonoBleedingEdge/bin/

    You should then have a working msc command:

    $ mcs --version
Mono C# compiler version 3.4.0.0

    For other Unity versions:

    Open a terminal and type find /Applications/Unity/ -name 'mcs' - this will give you a list of msc compilers in your unity installation, for example my list looks like this:

    /Applications/Unity/MonoDevelop.app/Contents/Frameworks/Mono.framework/Versions/2.10.12/bin/mcs
/Applications/Unity/Unity.app/Contents/Frameworks/Mono/bin/mcs
/Applications/Unity/Unity.app/Contents/Frameworks/MonoBleedingEdge/bin/mcs

    Check if any of these runs and pick that one. For 5.2, only the last one works without fixing paths inside the mcs script.
