Hi, Currently I have a Macbook Pro and I have a Dell Laptop. I am trying to transfer data from Dell Laptop to my Macbook via ethernet and its not working. The ethernet connection worked flawlessly with my previous Toshiba laptop that I had when I had to transfer data but its not working with the Dell Laptop or any laptop. I get this error and tried searching google and asked apple staff but did not find the solution. I tried it with other laptops and I am facing the same issue. I have about 300-400 GB of data to be transferred. I do not have a external HDD.
