iPhoto forced me to upgrade and I lost the last 5 years of albums. I burn CD's at the end of every year and I have Time Machine. I restored last nights back-up of photos but the same thing happened all over again.
I was forced to upgrade iPhoto and I lost the last 5 years of pics. Photos from 08-10 are still in there! I have Time Machine so I restored last night's back-up of the iPhoto library but the same thing happened all over again when I opened iPhoto.
