I just got a new Mac and did a manual clean install of everything. On the old Mac I had copied the current Lightroom 6 catalog.lrcat file. I reinstalled Lightroom CC via cloud and it works. When trying to change the catalog file via Catalog preferences I get the “Unexpected error opening catalog” message. “Try again” doesn’t help. I couldn't find any help in existing questions on this forum.
Both Macs were on the latest OS 10.10.4 and the latest LR CC version. I currently don’t have access to my old Mac to copy a new catalog file or use and old backup because I am travelling. Only have the new Mac and the old backup.
Did I make some kind of mistake or do I have a corrupt catalog?
Thanks for your help.
