I took my iMac to Simply Mac last week to install a new hard drive (mine was failing), add RAM and upgrade my OS to 10.8.5 (Mountain Lion). I've got everything up and running, but lost iPhoto in the process. This came already installed when I bought my computer back in 2008. The Apple web site is no help. It tells me that Photos comes with Yosemite, but I'm not running Yosemite. I need something to manage my photo library. Recommendations?
