I have two users on an IMac. In IPhoto for both users I have gone to Preferences and selected "look for shared photos," and "share my photos." In both cased the status is On.
User #1 can access the Library of User #2 by selection on the panel. However, User #2 CAN NOT access User #1's Library. Nothing displays with the name I have give it.
I just solved it. The user that is "sharing" their Photos must have both Look for shared photos and share my photos selected. the user that is "retrieving" photos just selects Look for shared photos.
I wrongfully assumed that it could be a default setting for both users.
Retrieving data ...
