Help! Can't Open Aperture Library (Requires iPhoto 9.4?)

Have you looked at your "DataModelVersion.plist" content? That is what the discussion in this thread was about at the end of last year (where to find it, what to look for, etc.).

In some cases, in that file the library is set to think it's an iPhoto library, instead of an Aperture library. In other cases, like mine, it was set to not be an iPhoto library (isIPhotoLibrary = False) but the application identifier for the database was iPhoto -- which caused a conflict.

You should look at the old vs. new version of the DataModelVersion.plist if you have it to see if you can find a difference there like the ones noted here.

I've tried without success. Neither iPhoto nor Aperture open the library anymore, despite both updating it an not being able to "use" it at the same time (Aperture opens nothing, iPhoto opens a blank library). They both change the DataModelVersion.plist to the following when they try to open it, though the application identifier seems to switch depending on what the last program to attampt an opening was. :

Hi,

I had same problem & I looks fixed it with:

Open the DataModelVersion.plist

Check the key:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>isIPhotoLibrary</key>

</true>

.....

</dict>

</plist>

The "<key>isIPhotoLibrary</key>" have not in my damaged iphoto library.

I added that & now can open with Apertrue.

I hope this can help you.
