Before You Start: Requirements Checklist
What You'll Need
macOS 12 (Monterey) or later. Windows support coming late 2026.
$20/month. Required for Cowork access. Free tier doesn't include Cowork.
Required throughout use. Disconnection terminates sessions. VPN recommended for reliability.
At least 500MB free for the desktop app and virtual machine.
Step 1: Download & Install Claude Desktop
Visit claude.ai
Go to claude.ai and sign in with your Claude Max account. If you don't have Max, upgrade first.
Navigate to Desktop App Download
Look for "Download Claude Desktop for macOS" in your account settings or dashboard. Click to download the .dmg installer file.
Install the Application
Open the downloaded .dmg file, drag Claude to your Applications folder. macOS may ask for security confirmation—approve it.
Launch Claude Desktop
Open Claude from Applications. First launch may take a minute as it initializes the virtual machine environment.
Step 2: Initial Configuration
First-Time Setup Wizard
Authenticate with your Claude account. Use the same credentials as claude.ai.
Look for the mode selector showing "Chat" and "Tasks". Click "Tasks" to access Cowork functionality.
Claude provides an interactive intro explaining capabilities and safety guidelines. Recommended for first-time users.
Step 3: Configure Folder Permissions (Critical!)
Important: Start with Low-Risk Folders
Don't grant access to critical data initially. Create a test folder to learn how Claude works safely.
Recommended First Setup
- 1 Create a folder called "Claude_Test" in your Documents
- 2 Add some non-sensitive test files (old documents, sample spreadsheets)
- 3 In Claude, grant access to only this Claude_Test folder
- 4 Confirm the permission when macOS prompts you
How to Grant Folder Access
In Cowork mode, Claude will ask permission before accessing folders. You can also:
- • Go to Settings → Folder Permissions
- • Click "Add Folder" and select desired directory
- • Choose read-only or read-write access
- • Approve macOS security dialog
Step 4: Your First Task (Hands-On Tutorial)
Beginner Task: Organize Test Files
"Organize the files in Claude_Test folder: create subfolders for Documents, Images, and Data. Sort files by type, rename with today's date prefix."
Files sorted into subfolders, renamed with consistent patterns. Total time: 1-2 minutes vs. 15-20 minutes manually.
Next Steps: Build Your Skills
Beginner Tasks to Try
- Rename files with consistent naming
- Create simple text reports from notes
- Organize downloads by date/type
- Extract info from PDFs to spreadsheet
Intermediate Tasks (Week 2+)
- Analyze data and create charts
- Generate formatted presentations
- Automate weekly reporting tasks
- Process expense receipts
Troubleshooting Common Issues
"Claude can't access this folder"
Solution: Check macOS Privacy settings. Go to System Preferences → Security & Privacy → Files and Folders → Claude. Ensure permissions are granted.
Session keeps disconnecting
Solution: Check internet stability. Claude requires constant connection. Consider using VPN for reliability, especially if on restricted networks.
Claude did something unexpected
Solution: Review your instruction clarity. Be more explicit: "Move files to Archive, do NOT delete anything" is better than "clean up files."
Desktop app won't launch
Solution: Restart Mac, check for app updates, ensure you have Claude Max subscription active, verify macOS version compatibility (12+).
Best Practices for Beginners
Always Maintain Backups
Use Time Machine or cloud backup. Never rely on AI automation being perfectly reversible.
Be Explicit in Instructions
Clear, specific commands produce better results. Include examples when possible.
Start Simple, Scale Gradually
Master basic file operations before attempting complex workflows. Build confidence progressively.
Review Results Initially
Inspect Claude's work closely when learning. This helps you understand capabilities and limitations.
