Turnkey setup for Ubuntu or macOS

Usage:

./machine-fresh-install.sh

After Setup

Both Platforms

• Install Tmux plugins: Prefix (Ctrl + Space) + I
• Install Vim plugins: :PluginInstall

Ubuntu

• Set ZSH as default shell:
  • Terminal → Preferences → New Profile → Command → use /usr/bin/zsh

macOS

• Use iTerm2 (installed by the script):
  • Open iTerm2 and go to iTerm2 → Settings → Profiles
  • Select "JetBrains Darcula" from the list (automatically installed)
  • Click Other Actions... → Set as Default
• Fix Ctrl+Space conflict with tmux prefix:
  • macOS uses Ctrl+Space for input source switching (you'll see an "A" icon toggling)
  • Go to System Settings → Keyboard → Keyboard Shortcuts... → Input Sources
  • Uncheck "Select the previous input source" and "Select next source in input menu"
  • This allows Ctrl+Space to pass through to tmux
• Grant clipboard access to iTerm2:
  • Go to System Settings → Privacy & Security → Accessibility
  • Add and enable iTerm2
  • This allows tmux-yank and other tools to access the system clipboard

Notes

• On Ubuntu the script uses apt to install prerequisites.
• On macOS the script relies on Homebrew (it will be installed automatically if missing).
