What's Wrong?

Environment: Claude Code Desktop (latest), CLI v2.1.114, macOS 26 Tahoe, MacBook Pro M5 Max, zsh, Terminal.app
Symptoms:

Desktop app: new sessions can be created and prompts can be typed in the input box, but both pressing Return and clicking the send arrow icon do nothing. No visual feedback, no error.
Desktop app: "Verify Claude CLI installation" onboarding task never completes.
CLI v2.1.114: OAuth flow where browser Authorize button appears to click but no callback ever reaches the CLI localhost listener. curl confirms the listener is reachable; browser (Chrome + Safari, clean profile) never completes the callback. Reproducible with Tailscale off, no firewall, no ad blockers.
CLI v2.0.33: OAuth works correctly, same machine.
CLI v2.1.114 TUI "Quick safety check" trust prompt does not accept Return/Enter to confirm the highlighted option.

Ruled out: keyboard (works in all other apps including claude.ai), browser extensions (Safari and clean Chrome profile both fail), Tailscale (quit during test), macOS Firewall, Private Relay, localhost routing (curl succeeds), custom input drivers (none installed).
Reproduction:

1. Fresh install of Node 25 via Homebrew
2. npm install -g @anthropic-ai/claude-code (v2.1.114)
3. claude → OAuth opens → Authorize → infinite hang
4. Downgrade to v2.0.33 → OAuth works
5. Upgrade back to v2.1.114 → cached auth works but TUI trust prompt does not accept input

What Should Happen?

It should run the prompt.
