Transfer photos from Nexus 4 to iPhoto

To get iPhoto to recognize my Nexus 4, I found I had to change the USB storage settings:

On the Nexus 4, go to SETTINGS. Bring up the STORAGEsettings. Tap the little three square dots icon in the top right corner. Select “USB computer connection“. This will bring up two connection options.

You can select “Media Device (MTP)” which is the default setting and will NOT allow you to import you photos. The other option is to select “Camera (PTP)“. This mode will allow you to import you photos. In Lightroom, for instance, the device immediately appears as “Nexus” in the photo importer.
