# MakeItOurs — Mac setup script
#
# Installs the command-line tools MakeItOurs needs to manage projects locally:
# git, Python 3.12 or 3.13, Homebrew, and OpenCode. Safe to re-run — each
# step checks what's already installed and skips it.
#
# Review this script before running it, then from Terminal:
#   chmod +x install-mac.sh
#   ./install-mac.sh
#
# Or run it directly:
#   curl -fsSL https://bengesoftwarellc.com/makeitours-website/install-mac.sh | bash
