How do I change my iPhoto Library location, i.e. to an external drive?
I would like to move my iPhoto Library to an external drive to save space on my MacBook Air internal drive. When I have copied the library to an external drive and told iPhoto that that is the default library, nothing is saved there, and the copy of the library on my internal drive is still being used. How do I get iPhoto to use the copy on my external drive as my default library? I would like to purchase a fast 3TB external drive, but do not want to do so if iPhoto will not use it as the default library location.
MacBook Air, OS X Mountain Lion (10.8.4)
