yes, that's what I have. After failing a few times and changing nothing, now, it's recognizing the RAWs but will not import. The error message, see screen grab below "cannot be read or destination folder is not writable." I send all my pics to an aux hard drive, thousands. tried naming the folder first even sending it to my computer hard drive. It's a brand new iMac with plenty of space.
So frustrating.
Thank you for your continued advice.

What is your Destination set to? It is probably pointing to a folder that your username does not have Write permissions to.
Are you using a card reader or connecting the camera directly to the computer? If you are connecting the the camera to the computer try getting a card reader or the SD card slot on your iMac.
