What is the exact version number of Lightroom that you are using? Please go to Help->System Info and report what version number is there. Do not tell me that you are "up-to-date" or using the "most recent" version.
Lightroom version: CC 2015.7
Make sure there are no external devices such as phones, tablets, track balls or pen devices attached to your computer. Try importing again.
There isn't. It's only my hard drive plugged in
I'm having the same issue.
Just the other week I am encountering the same issue. I keep all my images on external HD and always have. During this most recent time of importing images to catalogue I am getting the spinning ball in lower left.
I made sure I have updated - am on version 2015.8 . Running on MAC OS 10. (no change to computer).
I have not introduced any new software, hardware, etc. No new variables.
I'm at a standstill. I cannot upload images to process for clients and personal.
Anybody find a fix that a non-technical, non-IT / programmer can fix. (Note - saw other suggestions elsewhere for some complex changes - that is why i have software . . . to take care of complicated part)
Any help appreciated
