From what I’ve read, it appears that Apple plans to move away from its glitchy photo manager and into a new app. Apparently the new app wasn’t ready in time for the Yosemite operating system release, so iPhoto had to be tweaked for one last time, to be Yosemite-compatible.
I used the Yosemite version of iPhoto to make the slideshow below … book covers I’ve done with my literary friends, the Colombos. Seems to work properly.
