What's Wrong?

Summary

The /remote-control slash command consistently fails with "Remote
Control failed to connect: /login" in the Claude Code desktop app for
macOS, despite being signed in to an active Pro account.

Environment

• Claude Code desktop app for macOS
• Version: 1.8555.2 (a476c3), build 2026-05-22T23:04:37.000Z
• macOS Darwin 25.3.0
• Account: Pro plan (active), signed in via claude.ai
• ANTHROPIC_API_KEY: not set (shell or GUI launchctl env)

Steps to reproduce

1. Open Claude Code desktop app (signed in to Pro)
2. Start a new session
3. Type /remote-control
4. Error appears: "Remote Control failed to connect: /login"

Expected

A session URL and QR code for connecting from other devices.

Actual

Error: "Remote Control failed to connect: /login"

Troubleshooting attempted

• Full quit (Cmd+Q) and relaunch
• Sign out via Settings → Account, sign back in
• Verified ANTHROPIC_API_KEY unset (shell + launchctl + no shell

config files reference it)

• Re-authenticated via claude.ai in iPhone Safari, retried — same error
• Confirmed claude.ai/code works correctly in iPhone Safari, so account

auth is functional end-to-end

• /login and /status both return "isn't available in this

environment" in the desktop app — they appear to be CLI-only, so the
error message referencing /login may be misleading

Impact

Cannot connect MacBook session to iPhone Claude app as documented.

What Should Happen?

/login and /remote-control should work but instead i get errors saying "isn't available in this environment"
