How do I upgrade iPhoto on a family computer, when App Store tells me it is already installed?
How can I install iPhoto 9 and use iCloud Photostreaming, when App Store says it is already installed? I have two Apple IDs (family computer) which may be the root of the confusion. The one I use for iTunes purchasing and use solely on my work iMac has already upgraded successfully.
Mac mini, OS X Mountain Lion (10.8.3)
