macOS has a similar mechanism to LD_PRELOAD in Linux called DYLD_INSERT_LIBRARIES. Our current macOS binaries honor this environment variable, while the Linux ones do not. It is a good security practice to prevent usage of said environment variable to avoid preloading of arbitrary dynamic libraries.

To harden our binaries we can follow this StackOverflow answer advice.
