Q. Why wont my Nikon D3100 connect to my computer? The Nikon D3100 is brand new, and I took a large amount of photos that I want to upload, but when I connect it to my computer nothing comes up. I have a Mac OS X.
A. Insert the memory card in the card reader on your Mac and copy the image files that way. That is the best and fastest way to transfer the images to your computers hard drive.
