iPhoto should recognize the Android device as a camera immediately upon launch. There isn’t much to using iPhoto for this purpose, just launch the app after connecting the device to the Mac and it should backup all photos and provide an option to import them all.
Using Preview App for Image Transfers from Android to OS X
Preview is the standard image viewing application for OS X that can also serve as a means of copying or backing up photos from cameras, phones, and tablets.
- Launch Preview after connecting the Android device to the Mac
- Pull down the “File” menu and near the bottom of the menu options choose “Import from (device name)”
- Select the images to transfer, then choose “Import”
- Preview’s interface for copying pictures is a lot like Image Capture, but with fewer options, and there is also no option to automatically launch and import the photos upon connection.
