I have two mac's running the LR cc. The images are stored on an external. The catalog has been backed up and optimized and the preferences re-set. The problem is that the new iMac desktop doesn't show the Collections (some as old as 4 years). The laptop connect to the external has all of the collections but I can't seem to find a way to get them to show on the iMac setup.
I've looked on the Web for anyone else having a similar issue. No Luck.
Can someone smarter than this operator suggest a solution ?
