MapKit for the desktop?

Is there a framework similar to MapKit (i.e. that can displa开发者_高级运维y maps with overlays) for the desktop. Apple-supported, Google or third party/open-source.

I know of OpenStreetMaps, and I want to know what the options are.

The upcoming OSX Mavericks will have the MapKit. Go to https://developer.apple.com for the beta and information.
