There are 2 simple photos transfer app to transfer photos between iOS device and Mac:
- Use iPhoto to import your photos/videos when your iPhone is connected to the Mac.
- Use the "Image Transfert" app on your Mac to import your photos/videos from your iPhone to the Mac when your iPhone is connected to the Mac.
And the 3rd way, works only for photos and iCloud. If your iPhone is connected to iCloud and Photo Stream activated, simply go to iPhoto, and your photos will be there (i.e. it only works with photos and not with videos).
