Apple has made available the new "Photos" image editing software which is meant to replace iPhotos and Apperture. I took my laptop to the Apple Store for the upgrade and lost more than 5,000 images in the process. The guys at the Genius Bar believe my iPhotos application may have been corrupt prior to the upgrade. So...to those who might be considering the upgrade...beware.
Back-up before, just in case. . .
