I recently installed iLife 11 on my Macbook Pro and when i attempt to open iPhoto I get a message that says "In order to open iPhoto you need to update to the latest version". Currently i've been holding off on doing a software update since i'm still on Mavericks and i'm on an older mid 2009 Macbook Pro and i do not want to update to Yosemite as of yet. If i do a software update would I get a choice to update iPhoto instead of Yosemite? or does iPhoto need the latest OS version to run?
