I'm trying to synchronize a catalog with smart previews between two computers so that I can edit from either computer. I'd like to be able to switch back and forth seamlessly. Yesterday, it seemed like it was going to work. The catalog synced from my iMac to my laptop and when I pulled it up on my laptop it was exactly as I had left it. I did some work from my laptop while I was out, but, after letting the laptop sync until everything was green in Dropbox, when I open it up on my iMac I don't see the changes from my laptop.
