What's Wrong?

Environment

  • Device: M1 Mac Mini (headless, accessed via Tailscale)
  • macOS: [your version]
  • Claude Desktop: latest
  • Claude Code CLI: 2.1.119

What happened
Cowork sessions hang at "starting up" and never complete.
All sessions show cliSessionId: none in main.log.
After clearing sessions and signing back in, app shows "legacy model."
Claude Code CLI works fine independently. launchd jobs unaffected.

What I tried

  • Updated CLI from 2.1.29 to 2.1.119
  • Cleared claude-code-vm cache
  • Cleared local-agent-mode-sessions
  • Unlocked macOS keychain
  • Full reboot
  • Sign out / sign back in

Logs
[Attach cowork_vm_node.log and main.log from ~/Library/Logs/Claude/]

What Should Happen?

Claude Cowork should run the scheduled tasks and respond to keyboard input.
