Hey guys, I am trying to get iPhoto to work from one library on two different Mac's. I have the iPhoto library on a USB drive connected to my iMac. I can see the library and have imported it to both my iMac and MBP. When I make changes on my MBP, they are saved on my local MBP HD and not to the iPhoto library. Therefore I cannot see these changes when I work on the iMac. How can I have these changes saved to the iPhoto library on the USB drive? I have done some research about how this works but have another question. iPhoto is suppose to give you a warning that it is open on another Mac. ie so you can not have two users on one library at the same time. But I do not get this warning when opening iPhoto on both Mac's. Any thoughts are greatly appreciated.
