I hope someone can help me!!! Ok, I have a Mac I had an old operating system Mac OS X 10.7.5 so I tried upgrading, I had to install a new internal drive into my Mac Pro tower I was told to upgrade the operating system on the new drive well my LR catalog is on the old machintosh HD I’ve tried going to it and the LR is empty not only is it empty but it asks for a license which I have purchased but I don’t temeber it why is this happening? Should I copy everything over to the new drive? How do I do that would that help with my LR? I literally have thousands of sessions in that catalog and I was working on several weddings.
