I have a 10,000 pic iPhoto library on my 5 year-old MBP and a way-cool new MBP-retina. I can't move the library to the 256GB retina but don't want to edit on the dinosaur. Can I do this without jumping through too many hoops? It would be a pain to export to flash drive, import to retina, edit, export to flash drive and import to retina. I haven't done that but I'm afraid if I do I'll lose the date and event information. I care about maintaining those and album info. I don't bother with titles so that doesn't matter. Problematic idea #2 - open dinosaur in target mode from retina. I'd still be stuck with the slow disk speed though the editing would happen at light speed. Right? Problematic idea #3 - move files to Time Capsule. Trouble is the library file stays local, not on the TC but I guess I could move that to the retina. Problematic idea #4 - move files to external hard drive and the library info to the retina, taking dino out of the picture entirely. Suggestions? Ideas?
