In Lightroom I see Collection delete and create options, but not rename. Hovering over the collection name doesn't allow editing. Meanwhile, in Mac Finder the collection doesn't show up, just the imported folders.
Thanks for assistance.....
In the Collections panel, right-click a collection and choose Rename.
If this doesn't help, please do the menu command Help > System Info and copy the first ten lines here. That will let us know precisely which versions you're running.
"in Mac Finder the collection doesn't show up"
Collections exist in the LR catalog only and aren't visible outside of LR.
