  1. I have the same problem, even after iphoto 9.0.1 and the command sudo chmod…

  2. I am the exact same.. please can anybody help us?

  3. i found solution..
    Right-click (or control-click) on “iPhoto Library” in your ~/Pictures folder. Inside there is a folder called Database; open that. Then you need to edit the file called “DataModelVersion.plist”. To edit it you will need something like Property List Editor (which comes with the free Developer package from Apple), or you can use the freeware Pref Setter. There is also a way to edit it from the Terminal, but I’ll leave that for the geekier types to figure out. If you have one of those apps installed, you can just double-click the plist file to open it. In my case the child entry “IsPhotoLibrary” was present, but was strangely unchecked (i.e., False/No). You need to check it, or change its setting to True. If it’s not there, you need to add a child entry, named “isIPhotoLibrary” of the type “Boolean” and set it to True/Yes (checked).

  4. Lorcan you’re great! Thanks for your tip!
    To summarize, here’s what I’ve done to regain access to my iPhoto library:

    1) issued these 3 commands in a terminal window to reset the permissions (change username to your mac user and enter your password when required):

    sudo chown -R username (hit spacebar, drag iPhoto library into Terminal window, press return)
    sudo chmod -R -N (hit spacebar, drag iPhoto library into Terminal window, press return)
    sudo chmod -R u+rwX (hit spacebar, drag iPhoto library into Terminal window, press return)

    after this I was still unable to start iPhoto

    2) started iPhoto holding ALT and CMD keys and checked out some restore flags I don’t remember exactly (database and permissions for sure): didn’t work again

    3) found this Lorcan’s solution an voilà! Everything is in place again! My “IsPhotoLibrary” value was present but unchecked.

    Property list editor is part of XCode suite (http://developer.apple.com/technologies/xcode.html) you can download it for free after registration on Apple’s website.

    Hope thi to be useful!
