Personal checklist for setting up a new Mac's dev environment.
Mark Otto's personal dotfiles and Mac setup checklist — git config, bash profile, and a shell script to bootstrap a new machine. Aimed at Ruby/Jekyll developers, specifically those working in the GitHub ecosystem.
The .gitconfig includes aliases and color settings that are actually useful rather than toy examples. Using rbenv for Ruby instead of system Ruby is the right call and the readme explains why. The bash profile with git branch display in the prompt is a practical starting point people can build on.
Last touched in 2021 and shows it — references Atom (dead editor), Ruby 2.5.1 (EOL in 2023), and xcode-select workflows that have changed. The shell script is marked WIP and largely just opens URLs rather than automating anything. No zsh support despite zsh being macOS default since Catalina (2019). This is a personal config dropped on GitHub, not something designed for others to adopt.
