macOS is a Unix, and not built on Linux. This can bite you when trying to write scripts which support both platforms. I think most of us realize that macOS isn’t a Linux OS, but what that also means is that instead of shipping with the GNU flavor of command line tools, it ships with the FreeBSD flavor.

Credentials and other secrets (including your various system passwords) are stored inside your system keychain. They are encrypted, and cannot easily be stolen by a rogue script or application.

Only a tiny fraction of the code your application runs was written by you or your team. How do you know you can trust the code that was written by other people? Where would you even start? This piece is part of a larger series on Engineering for Site Reliability, specifically balancing stability against the edge of technology. What do I mean by “trust”? Movies and TV shows have given us a version of trust which essentially boils down to “Do you trust me?
