import from iPhoto hangs
I am trying to import a moderately large photo library (36,000 images) from iPhoto into Lightroom. I let the process run over night but it has been sitting at 94% with a message saying "Adding Stacks to Albums" for 4 hours. My computer is quite busy s I know that it is doing something but I see no progress. This is with Lightroom Classic CC version 8.1 running on a Mac Pro with 20 GB or RAM and 500 GB of free space on the internal disk where my photos are stored.
Should I kill the process and erase the partial results, and then start over? If I do, should I try the same IMPORT function or should I export the files from iPhone and then import into Lightroom. I would like to preserve my edits as well as the original versions and the metadata. The event structure is not as important as I will be reorganizing after I get the photos into Lightroom.
