Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

After MacBook Pro sleep/wake, Claude Code consistently returns 401 authentication errors. Only full macOS reboot resolves the issue.

Environment:

  • macOS (MacBook Pro)
  • Claude Code v2.1.142
  • This persists despite the v2.1.137 Keychain race condition fix

Steps to Reproduce:

  1. Use Claude Code normally (works fine)
  2. Close MacBook Pro lid (sleep)
  3. Open MacBook Pro (wake)
  4. Try to use Claude Code → 401 error every time

What I've tried (none work):

  • Deleting ~/.claude/.credentials.json and re-login
  • macOS logout/login
  • Only full macOS REBOOT fixes the issue

This suggests a deeper macOS system-level problem beyond the Keychain race condition fixed in v2.1.137. The securityd service appears to require a full system restart to resynchronize with Claude Code's OAuth tokens after sleep.

What Should Happen?

Sleep/wake cycles should not break Claude Code authentication. Users should be able to close and open their MacBook Pro without requiring a full system reboot.
