The Windows Phone 7 Connector app for Mac computers is ready and lets you transfer data between a WP7 smartphone and a Mac. It’s free and is available at the Mac App Store.
The app is designed to sync your media files from your Mac, with your Windows Phone 7 or Zune HD. You can also sync photos and videos you captured on your phone with your Mac, and, when needed, update your Windows Phone 7 software.
