Prefer the Mac App Store? Get Arrival there instead. Already using the direct download? If you have run 1.9.0 or later, the App Store copy keeps your settings — your schedule, your commute days, everything you have tuned. It asks for your two addresses and your Mapbox key once, on first run: those live in your keychain, and keychain items do not travel between two differently signed copies.
