7,000+ photo library missing
I have been unable to find my 7000+ iPhoto library and I am terrified that they're gone. To save disk space on my SSD, I pointed iPhoto to a library on my external disk, which is backed up on a weekly basis using using Carbon Copy Cloner. I have asked for help from their support desk but they said to ask Apple where the library might have been moved to. One thing I did recently was delete something called Mobilesync from my SSD after I found it had taken up my entire SSD. But iPhoto still opened ok after that. Now all my photos are gone. Please help. Thanks.
