How do I update iPhoto before upgrading OSX?
I'm running iPhoto 9.5.1 under Mavericks. I cannot upgrade to 9.6.1 (required for Yosemite or El Capitan) as App store tells me I need to run Yosemite to use load that version, but I cannot get Yosemite now and if I did, iPhoto would not run as it would not be 9.5.1 and I am informed that I would still be unable to upgrade it. Ditto if I moved to El Capitan. So what am I supposed to do and in what order?
