About 2 months ago I upgraded to Lightroom 2015.7 and it has been operating fine. No all of a sudden, when I tried to import (using the "add" option) from my external hard drive, it finds the files, but will not load any thumbnail previews for selection. The spinning loading symbol just spins without doing anything. I have tried importing from my hard drive and it does the same thing. I have closed down the program and reopened. I have rebooted my Mac. I'm not sure what else I can do. Help!
If you have updated you Mac Os to sierra(10.12) before Lightroom, then please uninstall the Lightroom and reinstall it from the creative cloud.
Let us know if that helps.
I am operating OS X El Capitan 10.11.6. I just uninstalled and reinstalled the software and it is still not importing. Please let me know what I can do.
