I recently added to my Apple arsenal an shiny new 24" iMac. When I got this is created myself as the user as you do. I put my copy of aperture on there and added some photos I had an an old external hard drive. All no problems so far. I decided to merge the information from my macbook pro onto the iMac as I wanted everything (music, pictures and files) all in one place. I did this using the firewire connection method and this created another user on the iMac. I was able to get all of my music from my iPod onto the main user on the iMac so everything was in one place and hen tried to do the same with the pictures in Aperture. This I can't do. I have tried copy and pasting. I have tried to load the pictures (doing this by exporting a group onto a new hard drive I bought) and then logging out and then back into the main user and then importing or dragging and nothing works. Aperture just will not allow me to import these photos. Any ideas of what I am doing wrong ?
