Hopefully this tip will help someone. After having no success with Android File Transfer (did not recognize device), Motorola Device Manager, and AirDroid (sent corrupted files), I was finally successful in transferring photos from my Motorola Droid HD to my iMac. First, connect the phone with a USB cable. Then use the main pulldown menu on the Droid (just pull down from the top of the screen) to determine the mode of computer connection. If "Camera" is checked, change it to "Media device." Then open Android File Transfer. Click "Internal Storage" at the top of the window, then open the "Camera" folder under the "DCIM" folder. It may take a while for the photos to appear in the Camera folder. Once they do, drag them to your Desktop or a folder on your Mac.
