Iphoto and Yosemite update
Updated my iMac and MacBook Air to OS X Yosemite. Everything seems okay except iPhoto. First it said needed to upgrade to an older version - now it says that in order to open iPhoto I need to update to the latest version and go to App Store. My iPhoto has over 30,000 photos of my kids growing up... I'm scared to update without checking first because when going to App Store, it does not prompt me to update, but to download for free iPhoto... If I do that, does it move all my photos automatically? If anybody else went through this process too, can you please advise?
iMac, OS X Yosemite (10.10)
