@lauren Using a Mac without Homebrew is a non-starter, full stop. It can be tetchy at times, but having access to things like a modern Python interpreter, an S3 command line, wget, ffmpeg, etc., is a necessity. I don't share @cstross dislike of the Terminal app so I can't speak to what iTerm2 offers in lieu, but macOS is definitely a way better *nix than any of the also-rans out there.
