How to install Social Engineering Toolkit in mac I want to install SET from this link: https://github.com/trustedsec/social-engineer-toolkit. If I am right this is the github repository. I have brew installed can't I grab it with homebrew and then use all the tools like I do in Kali? 

Or the other method downloading the zip file and compiling it....but I don't know either. Basically, teach me some way with which I can install and repository from github.

Thanks.
You don't need to compile the SET afaik, the install is:

    git clone https://github.com/trustedsec/social-engineer-toolkit
    cd social-engineer-toolkit
    python setup.py


now to start the setoolkit run

    ./setoolkit
