Installing Claude Code on macOS.
Five minutes from zero to a working Claude Code install on macOS. Tested on Sonoma and Sequoia.
Overview
Claude Code is an npm package. The install is one command if you have Node.js; about 10 minutes if you don't. macOS is the smoothest path.
Step 1 — install Node.js (if you don't have it)
Open Terminal. Check if you have Node:
node -v. If you see a version number above 18, skip to step 2.
If not, install Homebrew first (/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"), then brew install node.Step 2 — install Claude Code
npm install -g @anthropic-ai/claude-code. Wait ~30 seconds.
Verify: claude --version. You should see a version number.Step 3 — authenticate
Run
claude. It opens your browser to sign in with your Anthropic account. Approve. Return to the terminal — you're in.Want to Apply This to Your Business?
