The Mac is changing. We’ve long had a platform where out-of-the-box we were able to compile and run tools in a variety of languages. Over the years the evolving security posture has us moving from a POSIX-compliant platform capable of being used for widespread security research to a sandboxed operating system. And yet we need to be able to perform basic security research on a machine in an unaltered state.

Many applications now use a web or rest-based exchange of information. However, legacy tools and others still rely on socket comms. Thus we need to be able to interrogate, establish communications, and test the security of those using native Apple technologies. These tools are meant to provide ways for security researchers to borrow components for use in their own tools.
