iPhotos has lost my Photos when upgrading to Yosemite
When I upgraded to Yosemite like many people I have seen on forums there was a issue with upgrading the iPhoto library when upgrading to 9.6. Finally it looked like it had worked but now all of my photos do not appear in iPhoto. The files seem to be there still as the iPhoto library file is still1.26TB in size (i have a lot of photos). I have tried doing a full rebuild of the Library but it did nothing. I also purchased iPhoto Library Manager but this does not help either. Please can anyone help?
I am using iPhoto 9.6, OSX 10.10 (Yosemite) on a iMac (27-inch, Late 2013). The Library is stored on a "My Book Thunderbolt Duo", 8TB in raid 1 configuration.
