It is usually more helpful if you quote the exact complete unedited word-for-word error messages. Would you please be kind enough to do that?
However, it "can't read the files" is the error message I think it is, then your problem is that you don't have the proper permissions on the destination directory.
So, go to the IMport Dialog box, go to the Destination section on the right, and make a note of the EXACT folder shown there. Then, in your operating system, go to that exact directory and change the permissions to WRITE.
Some import files were not imported because they could not be read. (1)
I am pointing the images to 'highlighted' Macintosh HD.
I can import these files in LR CC on my iMac with the same card reader and cable.
Did you try the instructions I provided? It doesn't sound like it
Can you explain how to do this on a Macbook Pro?
What part of the instructions is unclear?

The Error is that the files cannot be READ how can this be a WRITE error?
That's how Adobe chose to word the error message, I have no further explanation of the wording.
Every time this error occurs, it is because the permissions are not set to WRITE>
I don't use iPhoto but the card and reader allow me to import to the HD on the Macbook Pro.
Why won't LR CC let me write to the HD?
My question was how do I access the area on the Macbook Pro that allows me to change the WRITE permission?
I found the LR CC directory and changed the permission for 'everyone' to read & write.
I can now import images into LR CC
An explanation of the error message wording about a read error which is really a write error:
A Copy type of Import happens in two phases:
First, LR copies from the camera/card to the destination folder—this is what is failing…silently.
Second, LR actually does the Import function from the destination, trying to find the files that should be in the destination, but it cannot so it reports the files cannot be read…which they can’t because they never made it to the destination.
Obviously, to us users who answer this question multiple times per day for umpteen years, but not Adobe, the failure of the initial Copy phase is where the error should be reported with a message that the files cannot be copied to the destination.
