After reinstalling OS X Mavericks and reinstalling my latest Time Machine backup everything seemed to work fine on my iMac. I pulled up several apps and tried them out; all seemed well. I had some new photos on my Nikon 7000 and decided to install them on the iMac. I plugged my Nikon 7000 via its USB connection and switched on the camera to initiate Aperture. Aperture came up in import mode installing my images. However, for some reason, Aperture didn't recognize that the majority of the images on the cameras memory card were already installed in Aperture. Consequently, it re-imported all 3,000+ images on the camera memory card! In the process of reinstalling all these images Aperture completely trashed my previously created Projects. Now I have over 1,626 Projects with screw ball labels like “Y33wfw8QQ10nRpJ%HuAAOg, Thumbnail, and oo2.” Each of these new Projects have an average of two images each randomly stolen from my original Projects! What a mess! And what is going on with Aperture? It would take me months to clean this mess up and restore my original Projects. This represents over three years of work. The bottom line is that my entire library of images is a shambles. Now what? What is the best way to recover from this fiasco? I'm thinking that throwing Aperture in the trash and using Time Machine to restore the application would be the best bet. Let me know what you think. I need help on this.
