Subscription Account Incorrectly Recognized as API Account on Specific Mac mini

Bug Description

Bug Report: Subscription Account Recognized as API Account on Specific Mac mini

Environment

• Claude Code version: 1.0.60
• Operating System: macOS (Mac mini)
• Terminal: Terminal.app
• Account email: info@unson.jp (has active subscription)

Issue Description

My subscription account (info@unson.jp) is incorrectly recognized as "Claude API Account" instead of subscription account on one specific Mac mini. This issue ONLY occurs on this particular machine.

Current Status Output

Login Method: Claude API Account

Expected Behavior

Should show subscription account status and allow usage of Pro/Max features without API billing.

Reproduction Steps

1. Install Claude Code via npm
2. Run claude
3. Login with subscription account
4. Check /status - shows "Claude API Account"

Troubleshooting Already Attempted

1. Complete uninstall and reinstall of Claude Code
2. Cleared all config files (~/.claude, ~/.config/claude)
3. Removed all Keychain entries related to Claude
4. Used /config clear command
5. Tried /logout and /login multiple times
6. Updated Claude Code with claude update
7. Created new macOS user account - same issue persists
8. Cleared npm cache and reinstalled

Key Information

• SAME account works correctly on other computers (recognized as subscription)
• Issue persists even with different macOS user accounts on this Mac mini
• Browser authentication completes successfully
• No error messages during login process

Unique to This Machine

This appears to be a machine-specific issue possibly related to:

• Hardware ID/fingerprinting
• Local network configuration
• macOS security settings

Please investigate why this specific Mac mini cannot properly authenticate subscription accounts while other machines work correctly with the same account.
