So of course, Apple finally gets the kinks out of the iPhoto library system and allows multiple users on one Mac to share a Library, just in time for my upgrade to Aperture 2. The Aperture 2 vault system specifically states it is not intended to be shared between multiple users…
I think I can use an external image location option and work from that, although I think is will be a small issue really, since Nadine will use iPhoto almost exclusively (easy, fast, and uploads to Facebook in one click -> just how she likes to edit images!) and I will be doing the deeper work within Aperture and Photoshop CS4.
Apparently it will allow multiple users to access the vault if all appropriate permissions settings are created and in place before the secondary user attempts to use it. I suspect it will need to be in the Users/Shared directory as well. More to come!
