Recently returned from a Disney Vacation with the family. I have approximately 1200 pictures taken and uploaded on my MBP in Aperture. I had to delete my card on my Nikon to take more pics. Now I want to transfer all the pics from Aperture on my MBP to Aperture on my iMac and then delete on my MBP. What would be the simpliest way without compromising the quality of my raw files.
