Binary releases for MacOSX expects an official python installation (the packages you get from python.org). It is highly suggested to have a python system wide installation (by default the official python distributions are installed in user's home directory) with the PATH environment variable including it (if you change the PATH variable remember to reboot the system before running the build procedure, this is not strictly required but will ensure the PATH is updated). If you want to have an idea of what the plugin can do, jump here: https://github.com/20tab/UnrealEnginePython/blob/master/tutorials/YourFirstAutomatedPipeline.md. create a new unreal engine blank c++ project (NOT a blueprint one, otherwise XCode will not be initialized), create a Plugins directory in the project directory, move to the Plugins directory and clone the plugin repository. move to the Plugins directory in the project directory and use git pull, move to UnrealEnginePython/Binaries/Mac from the Plugin directory, remove the plugin libraries to warn UnrealEngine to recompile the plugin, Create a new C++ project and close the editor once the project is fully started, go to the just created project directory and create the Plugins folder. It is meant to contain only functions that can be executed in script (but are also allowed in C++).
