Last night I went to drag and drop a couple of pictures into iphoto. When I opened it, it asked me to choose a library but the list was blank or to create a new library. This morning I have searched my imac to no avail, and on my back up drive, but found no library. Can someone please tell me where to find said libray, or what to do. If necessary I can download all the photos from my camera, but they were organized into various folders and don't want to have to do that again. Looking forward to a solution, thanks, Johan
After several futile attempts by looking on my iMac and 2 external drives, I simply attached the camera and downloaded my 400+ pictures. And all is right with the world. Johan
1. Can you now find the ".photoslibrary" files on the iMac?
2.a. Do you use Time Machine to back up your iMac?
2.b. Do you have any items excluded from its back up list?
2.c. Is it running/enabled?

Time Machine Excluded list

Time Machine is running/enaled
3. Do you use any other back up method?
