iPhoto is slow & won't import photos from camera
I updated the OS yesterday (OS X Yosemite 10.10.3) and since then, iPhoto is very slow. It will not load my photos that are currently on the computer nor will it import photos from my camera. I have run my camera battery down twice, now, waiting on it to try to do the import. I have had to force close iPhotos each time because it just sits there. Any suggestions?
iMac (21.5-inch, Late 2012), OS X Yosemite (10.10.3)
