Yes, more info. Recently helped a person with a mac who didn’t know she was using a passport for a PC and had same problem. If this could be your situation see this link:

Can't get photos from 2007 macbook onto passport Ultra

I have been trying to get photos from my 2007 macbook (has mountain lion so is compatible with my Passport Ultra). It shows up on my desktop but when I try to export a file from my photo library to it, it does not work. It says “Unable to create/volumes/my passport” IN addition, I cannot copy items by dragging them. Any assistance would be appreciated!
