macOS Terminal Installation Guide

I need a clear, beginner-friendly installation guide that walks macOS users through setting up my software entirely from the terminal/command line. The guide should start with any prerequisites (e.g., required versions of macOS, developer tools, Homebrew if relevant), then move into the exact commands to download, verify, install, and launch the application. Please explain each command briefly so users understand what it does, and include tips for common errors they might encounter along the way.

Because the focus is macOS only, you can ignore Windows and Linux paths, but feel free to note where a command would differ if it helps clarify why we do something a particular way. I’m looking for a polished document—Markdown preferred—with simple formatting, inline code blocks, and optional screenshots or terminal captures where it adds clarity.

Deliverables:
• A Markdown file (ready to drop into our GitHub repo)
• A PDF export of the same content for download

Acceptance criteria:
• Every command has been tested on the latest macOS release.
• The guide completes without manual intervention beyond what you document.
• Readers can confirm a successful install via a final verification step you specify.
