Travel time not automatically generated in Calenders I have just installed Mac OS X Mavericks and have been familiarising myself with some of the new features. One of the touted features was the ability to tell you the "travel time" for any given appointment. However when adding a new event to my calendar, the travel time is just specified times that I set, it will not show me how long it will take via car for example.

I have ensured that Calendars is allowed to use my current location, as well as Maps (which I believe is used to generate the time).
Try reentering the address so that Calendar registers it as an address (addresses will be suggested to you when as you type) rather than a mere string - that worked for me.
