I'm new here, so please be kind. I have a Nikon CP 8800. On my old iMac (2006) running Snow Leopard and iPhoto '09, imports went flawlessly. I recently bought a 2011 iMac running Mavericks. Same camera, same version of iPhoto, same USB cable. I connect, iPhoto opens to the import screen, the beach ball goes around for a few seconds, and the camera crashes. I get the dreaded "you didn't eject this device properly" message. I can only shut off the camera if I disconnect it from the cable. I know it's an old version of iPhoto, but everything else on it works. Also, I tried Image Capture, Lightroom (the latest) and just the Finder, same thing. The camera pops up, I see the images ready to import, then click, lights out. Any ideas as to whether it's the camera or Mavericks? I reset the camera, but same results.
