System, OS version, camera, file type, destination hard drive (internal, external)? Can you transfer files using Explorer or Mac Finder and then import them? Close all applications, reboot the system, and try again. Are you able to edit the one imported file in the LR Develop module?
System is Macintosh Desktop
OS 10.10.3 (Yosemite)
Camera: Nikon D3300
File Type: Tried JPEG alone and then JPEG + RAW
Destination HD (internal - for now)
I did re-boot and am able to import files through Photos and then onto desktop and presumably then into LR (one at a time!?)
I was able to develop the one file that was successfully imported.
Thank you for your time and feedback!
1) Check that the destination folder has full Read & Write permissions:
2) In menu Edit> Preferences uncheck 'Use Graphics Processor:'
3) If still the same issue post screenshots of these Import module settings or just paste the whole screen:
Then paste the progress bar in the upper left-hand corner and any error messages:
Its working!! Thank you so much!
