May i know are you able to import the images which are on your mac hard drive.
If i have a RAW file on my mac hard drive then yes i can import it.
Do you have any other memory card to try with .?
I have tried other cards no luck....
However today i did manage to copy and import via LR.
I spoke to apple today and they said it could be the OS. I am on the latest OS.
I just can't import from the card direct.....which is a little frustrating
HI, IS the operating system on your iMac different than the one on the laptop?
And which OS are you using on each machine?
I can import CR2 Raw files from my Canon 5 D III on any of my computers with no problems.
I am running OS 10.10.5, which is not the latest.
Check your destination folder to make sure the you have both read/write permissions. The message that Lightroom gives stating that the file cannot be read usually means that it cannot be written to the destination folder.
