I can't get iPhoto OR Photo to open on my iMac. They both work on my MacBook Air.
I tried loading them from the MacBook Air on a thumb drive and installing them on the iMac, bit it won't work. I get a problem message apparently referring to the lack of a library. But, the pics were on the app when I loaded it. I can't get a screen asking me to choose a library and it won't prepare or load a library. Anyone have a fix for this? Thanks!!
iMac (21.5-inch, Late 2013), iOS 8.3, Photo and iPhoto won't open.
