mac_dotfiles

Personal macOS terminal bootstrap for:

• Homebrew
• iTerm2
• Oh My Zsh
• Oh My Posh (custom theme)
• JetBrains Mono Nerd Font
• zsh-autosuggestions
• zsh-syntax-highlighting
• Custom iTerm Dynamic Profile

Anything already installed (Homebrew, each formula/cask, Oh My Zsh, the zsh plugins) is detected and skipped, so re-running is safe.

Install on a new Mac

Install Apple Command Line Tools first (git may need them):

xcode-select --install

Then clone and install:

mkdir -p "$HOME/Documents/Development" && cd "$HOME/Documents/Development" \
  && git clone https://github.com/jonserr/mac_dotfiles.git mac_dotfiles \
  && cd mac_dotfiles && make install

After the script finishes, open iTerm2, select the Jon Custom dynamic profile, and confirm the font is: JetBrainsMono Nerd Font and make sure to enable use ligatures and also set as default for new window.

iTerm2 picks up the profile automatically from the Dynamic Profiles folder (~/Library/Application Support/iTerm2/DynamicProfiles). Restart iTerm2 if it does not appear immediately.

What make install does

scripts/bootstrap.sh:

1. Installs Homebrew if missing (supports /opt/homebrew on Apple Silicon and /usr/local on Intel).
2. Installs git, gh, oh-my-posh, the iterm2 cask, and the font-jetbrains-mono-nerd-font cask — skipping any already installed.
3. Installs Oh My Zsh unattended (only if ~/.oh-my-zsh is absent).
4. Clones/updates zsh-autosuggestions and zsh-syntax-highlighting.
5. Copies the Oh My Posh theme to ~/.config/oh-my-posh/themes/.
6. Copies the iTerm Dynamic Profile into the iTerm DynamicProfiles folder.
7. Backs up any existing ~/.zshrc, then installs this repo's zshrc.
8. Creates ~/.hushlogin to silence the macOS "Last login" banner.

The iTerm profile

iterm/custom_profile.json is a valid iTerm2 Dynamic Profile — a top-level Profiles array of profile objects, each with a Guid and Name:

{
  "Profiles": [
    { "Guid": "jon-custom-profile-0001", "Name": "Jon Custom" }
  ]
}

The bundled file is a starting point (JetBrains Mono Nerd Font, dark background). To use your own exported settings, replace it with your profile — but keep the top-level Profiles wrapper, or iTerm won't auto-load it. Verify before pushing:

grep -n '"Profiles"' iterm/custom_profile.json

If that prints nothing, the file is a raw profile object rather than a Dynamic Profile wrapper, and iTerm will not load it from the DynamicProfiles directory.
