I lost complete access to aperture after upgrading to Yosemite. I did not know this would happen. Panicking.
I am in a complete panic. I did not realize that upgrading to Yosemite would block be from accessing Aperture. I just thought there would not be any more updates. I have lost all the effects loaded in there. But, I also cannot access my photos. I'm going crazy over here. I am trying to get the photos program to open. It's staying stuck at 0% progress in preparing photos. I need to access the things in there. I just got the manuals to try to teach myself Lightroom. I've been recovering from a severe injury and only have had one working hand for 3 months. I am so panicked, right now. I was not prepared for this change and would not have upgraded if I had known access would be lost.
What can I do, from Photos, once it finally cooperates, to get my photos to a Lightroom 5 program I have never used. Please be kind. I'm already giving myself a bad time, over here. I would deeply appreciate any guidance. I wish there was a way to keep my Aperture program usable until I was ready to make the change. That's what my plan was.
Aperture 3, OS X Mavericks (10.9.5)
