There isn't any version of iPhoto on this computer because it has been wiped and a fresh OS installed. (All of my Apps and data are on my new computer). iPhoto doesn't come standard as part of Snow Leopard OS, which is merely 3 years old. I can install a very OLD iPhoto (probably 6) that I have, but that is not ideal. Or I could find version 8 or 9 that works with Snow Leopard so my sister can use it. Here is my sister's scenario... Husband has recent Macbook Pro with latest iPhoto. Sister wants her own Mac (uses PC primarily for work) and they want to share same iPhoto Libraries on networked drive. BUT.... Sister has no way to access iPhoto Library from latest version because she cannot install latest version of iPhoto on her used computer, which still runs great with Snow Leopard.
By the way, I had purchased iPhoto '11 (version 9.2.1) in December 2011 and installed it FINE on this Snow Leopard computer. Now, suddenly, 9.3.2 cannot be installed on this same computer. If I login to the App Store, it wants to install 9.3.2 instead of 9.2.1 (which I purchased). VERY frustrating. The lifecycle of Apple's hardware and software is becoming increasingly short (and expensive!)
