Well,

as the subject says - this is about the well known exlcamation mark problem. I have read some discussion about, how to solve it and I will try it soon (its not with my Macs but with a friends one). The strange thing which I am seeking an explanation for is as following:

 

iPhoto V8.1.2 is working fine on a MacBook with Snow Leopard. For some reason the Library is located in /Users/Shared directory. When I now copy this entire iPhoto Library to an iMac with Lion installed, iPhoto (same version) shows the exclamation mark for many pictures. The library is located in /Users/Shared as well and the Users are named the same on boths Macs. The Users have also the same UID.

What can happen to the library when it is copied from Snow Leo to Lion?

As I saw that many pictures have extended attributes on the Library (both, iMac and MacBook), I removed all of the recursivly on the Lion-iMac (xattr -rc), but the explamation mark problem is still the same. chmod -R 777 and a chown -R username.staff did not solve it either. So, it seems not to be an issue with file system permissions.

 

Does anyone has an idea what is going on here?

 

Thx for any tips and tricks!

    Are you running a Managed or a Referenced Library?

     

    A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package

     

    A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management. 

     

     

    As I saw that many pictures have extended attributes on the Library (both, iMac and MacBook), I removed all of the recursivly on the Lion-iMac (xattr -rc), but the explamation mark problem is still the same. chmod -R 777 and a chown -R username.staff did not solve it either.

     

    Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things, deleting them or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.
