2026 Guide to Claude Code on macOS: A Developer’s Pitfall-Avoiding Walkthrough

Recently, I wanted to try using Claude Code for coding, but the official setup requirements—like needing an overseas account and dealing with unstable network connections—were discouraging. As a regular developer, all I wanted was a step-by-step guide that I could follow directly to get it working. This article compiles my entire process from installation to usage on macOS, hoping to help fellow developers who want to use Claude Code without hassle.

1. Prepare the Environment: Install Node.js
Claude Code relies on Node.js, requiring at least version 18. We recommend installing the LTS version.
Method 1: Download from the official website (Recommended)
Visit the Node.js official site, download the LTS version for macOS, and follow the installation wizard.
Method 2: Install via Homebrew
For command-line users, run: brew install node
Verify installation: Open Terminal and enter node --version (e.g., output v20.11.0) and npm --version (e.g., output 10.2.4).

2. Install Claude Code
Once Node.js is ready, install Claude Code globally using npm: npm install -g @anthropic-ai/claude-code
Verify installation: Enter claude --version; a valid version number indicates success.

3. Configure API Connection: Get an API Key
To use Claude Code, you need an API key. I used a proxy service (https://api.88api.shop) which I found cost-effective and stable. Steps to get the key:
1. Register and log in to the service.
2. Click "API Token" and then "Add Token".
3. Create a token (name it anything) and submit.
4. Copy the generated API key and keep it secure—it’s equivalent to your account password, so don’t share it publicly.

4. Solve Login Issues: Configure with CC Switch
Claude Code’s default login requires an official account, which is inconvenient for domestic users. The open-source tool CC Switch helps manage configurations and switch models easily. Steps:
1. Download CC Switch from its GitHub releases page: https://github.com/farion1231/cc-switch/releases (choose the macOS version).
2. In the CC Switch main interface, click the "Claude code" icon and then the "+" button to add a configuration.
3. Select "Custom Configuration" and fill in:
- Vendor Name: Any name
- API Key: Paste the copied key
- API Request URL: https://api.88api.shop/v1
4. Click "Advanced Options" to set the model (e.g., claude-sonnet-4-6; find model names in the "Model Square" if unsure).
5. Save the configuration, enable it, and restart Claude Code.
Note: If you encounter connection issues, try changing the API URL to https://api.88api.shop (remove "/v1") and restart.

5. Start Using Claude Code
Launch Claude Code: Open Terminal and enter claude.
Test it: Type "Hello"—a response means it’s working.
Common commands:
- /model: Switch AI models
- /help: Show all available commands
- /clear: Clear current conversation
- /exit: Exit Claude Code
- /resume: Restore previous session
- /cost: Show session cost and duration

Conclusion
The process isn’t complicated—focus on three key steps: setting up Node.js, getting the API key, and configuring CC Switch. Follow these steps to avoid most pitfalls. Now, using Claude Code for coding or troubleshooting is much easier, and switching models only takes a quick config change. If you run into issues, feel free to leave a comment to discuss solutions.
