I have been using iPhoto and it keep updated.  Using v.9.4.2.  MaxOS is current v.10.7.5.  I have tried Aperture but not really used it and don't keep it updated.  It is v.2.1.4.  Recently I chose a pull-down setting in iPhoto to open photos in Aperture library (or somehting like that, I don't remember, I was just fumbling around).  I got a pop-up window stating:

"Aperture library needs to be upgraded.

To open this Aperture library in iPhoto, you need Aperture 3.3 or later.

Click Update Aperture to buy the latest version of Aperture from the Mac App Store.


After installing the update, open your library in Aperture to upgrade it."


The only options on this pop-up window are "Quit" or "Update Aperture".

If I choose "QUIT", iPhoto closes and I can't open the photos in my iPhoto library.

If I choose "Upgrade Aperture" I am re-directed to the APP Store where I can purchase Aperture for $79.99.


I didn't intend to open Aperture and I don't want to upgrade Aperture, either.

I only want to open iPhoto without the Aperture library.

I can't figure out a way to get me back to opening my photos in iPhoto without this pop-up window.


I thought there would be an iPhoto or Aperture preference file ending with ".plist" in iMacHD \ Library \ Preferences.  If so, I would delete it and then try to re-launce the iPhoto application.  I only found one relating to Aperture.  I deleted it and tried re-launching iPhoto and still get the pop-up window asking to upgrade Aperture.


I would like to remove Aperture and use only iPhoto, if I can.

    Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.


    (On 10.7: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)


    (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)


    What's the plist file?


    For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
