macOS — first launch
The build isn't notarized (no Apple Developer cert). Unzip, then right-click Dual Pilot.app → Open → Open. If macOS still blocks it, run in Terminal:
xattr -dr com.apple.quarantine "/Applications/Dual Pilot.app"Windows — first launch
Unzip anywhere, run Dual Pilot.exe. SmartScreen will warn — click More info → Run anyway (unsigned build).
Uses your subscriptions
Talks to chatgpt.com and claude.ai with your existing logins — your Plus/Pro plan, your chat history.
Side by side
