Can't transfer my pictures
I'm trying to transfer my iPhoto library from my old mac to my new mac via an external HD (WD my passport). I had downloaded the iPhoto library upgrader, which leads me to a message that says "Your library can now be upgraded by the current version of iPhoto. Do you want to launch iPhoto?". When I launch iPhoto, it says the photos need to be prepared and leads me back to the instructions to download the upgrader. Hoping someone can help me!
MacBook Air, OS X Yosemite (10.10.2)
