If your Mac is at OS 10.7.3 and you install the beta version of Messages for the Mac, and you can use Messages to transfer files (photos, videos, attachments, contacts, and locations) wirelessly between between your iPhone and Mac. These file transfers can work in both directions. For an example; to transfer a video go into Photos on your iPhone, and share it as a “Message” texting the video clip to yourself. Messages for the Mac syncs with iPhone’s Messages and once your clip arrives on your Mac, drag the video thumbnail to where you want to save your video. Keep in mind, you want send iMessages (blue colored), not regular carrier text messages (green colored), and iMessage texting with attachments only works between Macs and Apple iOS devices with iOS 5.
