Who's super knowledgeable about MAC computers? I am trying to upload iPhotos/Photos from an external hard drive to Google Photos. Can you assist or at least point me in the right directions. Before you ask, yes I googled it. But the answers that keep coming aren't helping. These pics/vids do not exist on my computer, only on the hard drive but they were put there through iPhotos (now called Photos. There are two libraries; one called iPhotos: 188gb & the other called Photos 168gb).
