Everything you need to get your Mac ready for vibe coding
Before you start: Read through this entire guide first so you know what to expect. Then use the interactive prompt in Guide 02 to walk through setup step-by-step with Claude's help.
What You'll Install
Xcode Command Line Tools — Essential developer tools for Mac
Homebrew — Package manager for installing software
Node.js — JavaScript runtime for web development
Git — Version control to track your code changes
Cursor — AI-powered code editor
Claude Code — AI coding assistant that runs in your terminal
Part 1: Open Terminal
Step 1: Press Command + Space to open Spotlight Search
Step 2: Type "Terminal" and press Enter
Step 3: A window will open with a command prompt — this is where you'll type commands
Part 2: Install Homebrew
Homebrew is a tool that makes it easy to install software on your Mac. It's like an app store for developer tools.
Step 1: Install Xcode Command Line Tools first:
xcode-select --install
A popup will appear — click "Install" and wait for it to finish.
Click the "Download" button (it should automatically detect you're on Mac)
Wait for the download to complete — you'll see a file called something like Cursor-0.x.x.dmg in your Downloads folder
Step 2: Install Cursor
Open your Downloads folder (click the Finder icon in your Dock, then click "Downloads" in the sidebar)
Double-click the Cursor-....dmg file you just downloaded
A new window will open showing the Cursor icon and an Applications folder
Drag the Cursor icon onto the Applications folder — this copies Cursor to your Applications
Wait for the copy to complete
You can now close this window and eject the disk image (right-click → Eject)
Step 3: Open Cursor for the First Time
Open Finder and go to Applications
Find Cursor and double-click to open it
You may see a warning: "Cursor is an app downloaded from the Internet. Are you sure you want to open it?" — Click "Open"
Cursor will launch. It may ask you to sign in or set up some preferences — follow the prompts
Step 4: Add Cursor to Your Terminal PATH
This lets you open Cursor from Terminal by typing cursor . — very useful!
With Cursor open, press Command + Shift + P on your keyboard
A search bar will appear at the top of Cursor — this is the "Command Palette"
Type: shell command
You'll see an option that says "Shell Command: Install 'cursor' command in PATH"
Click on it (or press Enter when it's highlighted)
You should see a success message
Step 5: Test It
Let's make sure Cursor can open from Terminal:
Open Terminal (if it's not already open)
Type this command and press Enter:
cursor --version
You should see a version number. If you see "command not found", close Terminal completely, open it again, and try once more.
Pro tip: You can open any folder in Cursor by navigating to it in Terminal and typing cursor . (that's "cursor" followed by a space and a period). The period means "this folder."
Part 6: Install Claude Code
Step 1: In Terminal, run:
npm install -g @anthropic-ai/claude-code
Step 2: Navigate to a project folder and launch Claude Code:
mkdir -p ~/Projects/my-first-project
cd ~/Projects/my-first-project
claude
Follow the prompts to log in with your Anthropic account.
You're ready! Head to Guide 03 "Your First 30 Minutes" to build something real.
Guide 02
Get Started Prompt
Copy this into Claude.ai for interactive setup help
Copy everything in the box below and paste it into a new conversation at claude.ai. Claude will walk you through each step one at a time.
Interactive Setup Prompt
Hi Claude! I need your help getting set up to code for the very first time. I'm on a Mac and I have zero coding experience. I need you to be my patient, step-by-step guide through this entire process.
Here's what I need to set up:
1. Xcode Command Line Tools
2. Homebrew (the Mac package manager)
3. Node.js (using nvm)
4. Git
5. Cursor (the AI-powered code editor based on VS Code)
6. Claude Code (the CLI tool from Anthropic)
And then I need to:
7. Create my first project folder
8. Set up that project with the right configuration files
9. Learn how to use Claude Code to start building
IMPORTANT INSTRUCTIONS FOR YOU:
- Assume I know NOTHING about coding or terminals. Explain every single step.
- Tell me exactly what to click, what to type, and what I should see after each step.
- Only give me ONE step at a time. Wait for me to confirm I completed it before moving on.
- If I run into an error, help me troubleshoot it before continuing.
- Use simple, non-technical language whenever possible. If you use a technical term, briefly explain what it means.
- When you tell me to type a command, put it on its own line so it's easy to copy.
- After each step, ask me "What do you see?" or "Did that work?" so we stay in sync.
Let's start from the very beginning. What's the first thing I should do?
What Happens Next
After you paste this into Claude chat, it will begin walking you through each step one at a time:
It will ask you to open Terminal
It will help you install Xcode Command Line Tools
It will guide you through installing Homebrew
It will help you install Node.js, Git, and other tools
It will teach you how to launch Claude Code
Tips:
Keep the Claude chat conversation open the whole time
If you get an error, copy the ENTIRE message and paste it to Claude
This takes about 30-60 minutes — don't rush it
You can take breaks! Just come back and say "I'm back, where were we?"
Guide 03
Your First 30 Minutes
Build a real webpage in your first Claude Code session
Everything is installed. Now what? This guide walks you through your very first Claude Code session. You'll build something real in 30 minutes and see it running on your screen.
Step 1: Create Your Project Folder
Every project needs its own folder. Think of it like creating a new folder for a school project — all your files will live here. Choose ONE of these two methods:
Option A: Create Folder Using Finder (Easier for Beginners)
Open Finder — Click the Finder icon (the smiling face) in your Dock
Go to your home folder — In the menu bar, click Go → Home (or press Command + Shift + H)
Create a Projects folder (if you don't have one):
Right-click in empty space
Select "New Folder"
Name it Projects and press Enter
Open the Projects folder — Double-click to open it
Create your project folder:
Right-click in empty space
Select "New Folder"
Name it my-first-project (use dashes, no spaces!) and press Enter
Your folder is now at: ~/Projects/my-first-project
Option B: Create Folder Using Terminal (Faster Once You Learn It)
Open Terminal — Press Command + Space, type "Terminal", press Enter
Create the Projects folder and your project folder in one command:
mkdir -p ~/Projects/my-first-project
This command does two things:
mkdir = "make directory" (create a folder)
-p = create parent folders too (so it creates both "Projects" and "my-first-project")
~ = your home folder
That's it! The folder now exists.
Naming tips:
Use lowercase letters
Use dashes (-) instead of spaces: my-cool-app not my cool app
Keep names short but descriptive
Step 2: Open Terminal in Your Project Folder
Now we need to tell Terminal to "go to" your project folder. Choose ONE method:
Method A: Drag and Drop (Easiest)
Open Terminal (if not already open)
Type cd (that's "cd" followed by a space) — don't press Enter yet!
Open Finder and find your my-first-project folder
Drag the folder from Finder and drop it into the Terminal window
You'll see the path appear after "cd "
Now press Enter
Method B: Type the Path (Once You Know It)
Open Terminal
Type this command and press Enter:
cd ~/Projects/my-first-project
cd means "change directory" — it tells Terminal to go to that folder.
Verify you're in the right place:
pwd
This should print: /Users/yourname/Projects/my-first-project
If you see that path, you're in the right folder!
Step 3: Start Claude Code
Now that you're in your project folder, start Claude Code:
claude
You should see Claude Code start up with a welcome message. Once you see the prompt where you can type, you're ready to build!
If you see an error:
command not found: claude — Claude Code isn't installed. Go back to Guide 01, Part 6.
Not authenticated — Follow the login prompts that appear.
Minutes 2-5: Tell Claude What to Build
We're going to build a simple personal webpage. Type this into Claude Code:
I want to build a simple personal webpage. Create an index.html file with a clean, modern design. Include my name as the heading (use "Your Name" as a placeholder), a short bio section, and a list of 3 hobbies. Style it nicely with embedded CSS -- use a dark background with light text, nice fonts, and good spacing. Make it look professional, not like a school project from 1999.
Minutes 5-8: See Your Creation
Open your HTML file in a browser:
Open Finder
Navigate to your project folder
Double-click index.html
You should see a professional-looking webpage. Not bad for 5 minutes!
Minutes 8-12: Customize It
Tell Claude to personalize it:
Change the name to [YOUR ACTUAL NAME]. Update the bio to say: "[Write 2-3 sentences about yourself]". Change the hobbies to [list your actual hobbies].
Refresh your browser (Command + R) to see the updates!
Minutes 12-18: Add More Pages
Add an About page (about.html) with more detailed information about me. Include sections for my background, skills, and goals. Add a navigation bar to both pages so I can click between them. Make sure the nav bar looks good and highlights the current page.
Minutes 18-22: Make It Interactive
Add a dark mode / light mode toggle button in the top right corner of the navigation bar. When clicked, it should switch between a dark theme and a light theme. Remember the user's preference using localStorage so it persists when they refresh.
You just added interactive functionality to a website. With zero coding knowledge.
Minutes 22-25: Save Your Work
Initialize git if it's not already set up, then commit all our work with a good commit message describing what we built.
Congratulations! In 30 minutes, you built a multi-page website with dark mode toggle, customized it, and saved your work with Git. This is how vibe coding works!
Guide 04
Tips for Working with Claude Code
Best practices for effective vibe coding
How to Give Good Prompts
Be Specific, Not Vague
Bad
"Make the app better"
Good
"Add a login page with an email field, password field, and a submit button that validates the email format"
Describe What You Want to See
Bad
"Fix the homepage"
Good
"The homepage should show a welcome message at the top, a list of recent posts below it, and a footer with contact info"
Work in Small Steps
This is the #1 most important tip. Don't try to build everything at once.
Don't do this: "Build me a complete e-commerce website with user accounts, product listings, a shopping cart, checkout with Stripe, order history, admin dashboard, and email notifications"
Do this instead:
"Create a homepage that displays a list of products"
"Add a product detail page that shows when you click a product"
"Add a shopping cart that lets users add and remove items"
...and so on
Always Review What Claude Writes
Claude Code will ask for your permission before making changes. Take a moment to review:
Read the file names it wants to change or create
Skim the code changes
If something looks wrong, ask about it before approving

Troubleshooting Guide
When things go wrong (and they will)
The Golden Rule: When something goes wrong — don't panic, don't randomly delete things. Copy the error message and paste it into Claude Code or Claude chat. Everything has a fix.
"There's a Wall of Red Text in My Terminal"
Red text usually means an error. It looks scary but it's normal and almost always fixable.
Don't panic — read the LAST few lines (that's where the actual error is)
Copy the last 5-10 lines of red text
Paste it into Claude Code and ask: "I got this error. What does it mean and how do I fix it?"
"Claude Changed a Bunch of Files and Now Nothing Works"
Option 1: Ask Claude to fix it:
"The last changes you made broke the app. Here's the error: [paste error]. Can you fix it or undo those changes?"
Option 2: Undo all uncommitted changes:
git checkout .
Option 3: Undo just one file:
git checkout -- path/to/file.js
"I Closed the Terminal and Lost Everything"
You didn't lose everything! Your files are still on your computer.
Your code files are still in your project folder
Your dev server stopped (just restart it with npm run dev)
Claude Code conversation is gone, but just type claude to start fresh
"command not found"
Close and reopen Terminal, then try again
If it still doesn't work, the tool may not be installed — re-run the installation step
"Permission denied"
Put sudo in front of the command:
sudo npm install -g @anthropic-ai/claude-code
It will ask for your password.
"Port 3000 is already in use"
Find what's using the port and kill it:
lsof -i :3000
kill -9 PID_NUMBER
Or just use a different port: PORT=3001 npm run dev
Guide 09
Transitioning Existing Projects
Taking over a project from another developer
You have a project that was built by another developer, and now you want to use Claude Code to continue working on it. This guide helps you gather everything you need.
Questions to Ask Your Developer
Copy this list and send it to your developer:
Project Basics
What programming language(s) does the project use?
What framework(s) does the project use?
What version of Node.js / Python / etc. should I use?
Source Code
Where is the source code hosted? (GitHub URL)
What branch should I work from?
Can you add me as a collaborator?
Environment Variables
Does the project use a .env file?
Can you send me a copy or list all required variables?
Database
What database does the project use?
How do I access it?
Are there migrations I need to run?
Running the Project
What are the exact commands to install dependencies and start the project?
Are there any special setup steps?
What You Need (Minimum)
Access to the source code (GitHub invite or zip file)
A list of environment variables and their values (.env file)
Instructions for how to run the project locally
Access to the database (or instructions for setting one up)
Getting Started with the Project
Follow these steps carefully. Each one builds on the last.
Step 1: Get the Project Files onto Your Computer
Your developer will give you access one of two ways:
Option A: If they gave you a GitHub link
Open Terminal (Command + Space, type "Terminal", press Enter)
Navigate to where you want to put the project:
cd ~/Projects
Clone the project (replace the URL with your actual GitHub link):
Double-click it to unzip (creates a folder with the project)
Drag the unzipped folder to your Projects folder
Open Terminal and navigate to it:
cd ~/Projects/project-name
Step 2: Add the .env File (Environment Variables)
The .env file contains secret settings like API keys and passwords. Your developer should send you this separately (never through GitHub — that would expose the secrets!).
Your developer will send you the contents (might look like this):
In Terminal, make sure you're in the project folder, then create the file:
touch .env
Open the file in a text editor:
open -e .env
Paste the contents your developer sent you
Save the file (Command + S) and close the editor
Why can't I see the .env file in Finder? Files starting with a dot are "hidden" by default. Press Command + Shift + . in Finder to show hidden files.
Step 3: Install Dependencies
Most projects use code libraries written by other people (called "dependencies"). You need to download these before the project will work.
Make sure you're in the project folder in Terminal
Run this command:
npm install
Wait for it to finish — you'll see a lot of text scrolling by. This is normal!
When it's done, you'll see your command prompt again. You might see some "warnings" (yellow text) — these are usually fine to ignore.
If you see red "error" text: Copy the last 10 lines and paste them to Claude Code or Claude.ai for help.
Step 4: Start Claude Code and Create a CLAUDE.md File
This helps Claude understand the project so it can help you better.
Make sure you're still in the project folder in Terminal
Start Claude Code:
claude
Once Claude Code is running, paste this prompt:
Analyze this entire project and create a detailed CLAUDE.md file. Include what the project does, how the files are organized, what technologies it uses, how to run it, and any important patterns you notice.
Claude will read through the project and create a helpful reference file
Step 5: Try Running the Project
Now let's see if everything works! The command to run the project varies, but here are the most common ones:
Ask Claude Code: "How do I run this project locally?"
Or try these common commands (one at a time until one works):
npm run dev
npm start
npm run start
If it works, you'll see a message like "Server running on http://localhost:3000"
Open your web browser and go to http://localhost:3000 (or whatever port it shows)
You should see the project running!
To stop the server: Go back to Terminal and press Control + C
You're ready! You now have the project running locally. From here, you can use Claude Code to explore, understand, and make changes to the codebase.
Guide 10
Project Setup Files
Starter files Claude Code can create for you
Once you have Claude Code installed and running in your project folder, paste this prompt:
"Read the project setup files guide and create all of the standard project files for me: .gitignore, .cursorignore, .cursorrules, CLAUDE.md, package.json, and a starter index.js file."
Files That Will Be Created
.gitignore
Tells Git which files to NOT track (dependencies, secrets, build files)
