Hi Terence,
I have iPhoto'11 (9.4.2)
I do have a back-up in an external hard drive
I bought a new MacBook Pro and was doing the file transfer with the "Genius" guidance. This has not been the smoothest process. In anycase, it seemed that it had gone right today (and I'm not sure that my iPhoto issue is related to the transfer of files or if it is a bug of iPhoto.
What happened was that after having transferred all my files, I got into iPhoto and began to re-order it. I had some duplicate photos that I had been meaning to prune for a while, I also wanted to delete some excess pics and while doing this, I also began to re-sort the Events Library ... mostly consolidating some events).
It all seemed to be going fine until - after a few hours of work - iPhoto crashed. I reopened it without thinking too much about it and resumed my work. However, after a while I noticed that when going to the "Events" section, there were many "Events" that had no thumbnails!
Some of these corresponded to events that I had eliminated (by deleting or transferring all their pics to other events), which surprised me as - theoretically - these should no longer exist. Of course, these event folders were empty
But there are other event folders which do correspond to events I had been editing, which had plenty of pictures; yet they were showing "0" pictures! However, when I click on the folder, the pictures do appear. But for some reason their Event folder shows "0" and no thumbnail.
Lastly, there are some existing event folders that show a thumbnail, but also show an alleged high number of pics that do not correspond with what is meant to be in that folder. If I scroll the mouse over the thumbnail, I will see an endless number of pictures - not necessarily corresponding to that event folder - ; but when I click on it, the actual pictures and the number of pictures is in accordance to what I had done when creating the folder. In other words, the thumbnail information does not match what is actually in that event folder.
My initial fear was that pictures had been deleted by iPhoto, but they appear to all be there ... and the "Photos" Library does not seem to have been afected.
I tried shutting down iPhoto ... and the computer ... hoping that it would re-open corrected, but to no avail.
I guess my MacBook is new enough, that I could re-install the software back to scratch and repeat the whole process, so as to start again from a clean sheet. But that does not guarantee the issue will not repeat. I am basically losing trust on iPhoto (and on Apple).
I've booked another Genius appointment for tomorrow (which is frustrating as I'm spending my weekend going to an Apple Store to repeat the same story over and over without getting my problem solved!) Any insights are most welcome!
Thanks a lot!
Max
