Reverse Engineering on macOS

Some notes, tools, and techniques for reverse engineering macOS binaries.

How to Defang macOS System Protections

If you want to change things on the root drive of a Mac you will need to take some steps to disable the built in security of the system. Most of these steps are the same regardless if you are on Intel or Apple Silicon. If there is a difference it is noted.

Note that all of these things put a Mac into an unsupported and less secure state.

Make sure you either perform these steps in a VM or that you reset the protections after you are done poking around

Protections and Terms

(This list is not exahustive on the details of each. Check the links at the end for more info.)

All credits go to by Bryan Roessler for his original post that I followed on how to setup LetsEncrypt wildcard certificate auto-renewal with Namecheap. I highly recommend you read his tutorial first and if you bump into issues, check out this gist next.

Unfortunately the original article is not up-to-date and doesn't have the option to leave comments so I can't communicate with the author for updates so I decided to write the updates in a Gist. I highlighted the sections that required an updated with Correction #:. I managed to get the correct setup with the help of the amazing guys at LetsEncrypt community. Here's the help thread.
