macOS setup · terminal workflow · measured performance

dot-files

My working setup for Ghostty, zsh, Bash, Vim, tmux, Git, and repeatable machine configuration. Small tools, explicit trade-offs, and checks I can rerun.

Set up the dotfiles

On a Mac, clone the repository and run the setup script. It installs the command-line tools, Ghostty, Oh My Zsh, and pinned Vim plugins, links the configuration files, and checks that everything loads correctly.

git clone https://github.com/marianposaceanu/dot-files.git ~/dot-files
cd ~/dot-files
brew install borkdude/brew/babashka
bb bootstrap/install_macos.clj
Review before you run it The installer replaces supported configuration files with symlinks. If a file already exists, it moves it to a timestamped backup first. The script is safe to run again if setup is interrupted or the repository changes.
