Some help please. I have bought a SDXC card for my Mac Mini. I want to copy photos I have on iPhoto to the card so I can then put the card into a digital photo frame. I have put the card into the Mac slot and the card appears on my desktop. Do I just drag and drop the photos from iPhoto over to the card icon or will that delete them from iPhoto? I don't want them deleted from iPhoto, just copied. Also I have read some sites that say the card needs to be formatted but no option came up asking if I wanted it formatted, do I have to do this first?
