I am not a very tech savvy person, just FYI.
I had a 2012 Macbook Pro, the video card died and I bought the new MacBook Pro which now has the new hook-ups and I bought an adapter for the USB port. On my old MAC, I was able to transfer files, no issues. Now with my new MAC, it is not letting me back up anything, no drag and drop to the external HD. I can, however drag files from HD to my laptop.
Anyone familiar with this problem?
