Could you please specify the make and model of the camera?
What if you copy a few images from the card to Mac hard drive using Finder and then, try to import in Lightroom?
Thank you for your reply. I have a Nikon D 90. I am reluctant to make the process more complicated, especially as my PC worked without these extra stages.
I may have solved the problem. I shut down the iMac and reopened it. The annoying Mac pictures program came up when I connected my Camera so I made sure the program was closed and then proceeded to download the photos. It worked as it should have.
I don't know which if any of these made the difference. I will try this manoeuvre again with my next batch of photos and can I contact you if I have problems?
Is there anything else you can suggest that I should try?
Thanks for the update.
If its working fine now, then the issue is resolved.
You do not have to try anything else. Restarting machine fixed it.
