Please state your exact operating system version.
Please state the exact version NUMBER of Lightroom that you are using (go to Help->System Info)
OS X Yosemite Version 10.10.5
From where are you importing the files? Camera? Card? Disc? HDD?
Are you able to try a different method? Card Reader/Cable
Are you able to transfer the images to your Hard Drive via drag and drop in the Finder?
If so, what happens when you try to import from there?
Thank you for the advice. I was using my SD card reader. I did what you suggested (copied to my HD and imported from there) and it worked. So I'm guessing I have a bad SD card or my Card Reader is toast. I will try different ones today to try and troubleshoot.
I'm still concerned about my MAC not being able to upgrade to the latest IOS. I'm sure that is going to affect me at some point o I need to start saving my money for a new one.
Thanks for your suggestion. I ended up being able to import from my hard drive so I'm thinking I have a bad SD card or my Reader is toast. My computer is a 2009 so I wouldn't be surprised. Will troubleshoot these things today.
Thanks again for your help.
