I am using a MacBook Pro and have used Aperture 3 to edit in the past. Want to migrate to LR 6. I moved images to an external HD (Seagate) and then imported files as categories (i.e. Animals, Black and White, etc) Now I try to go from the LR 6 library (where I see the images fine) and click on Develop. I then get the message, "The File could not be found". Any ideas on how they can be found? (maybe is it how I have preferences set up?) Thanks
The images that says " File could not be found" is because the images have been moved to any other location on your drive.
