Hello everyone ! I have a late 2013 retina Macbook Pro 13 inch model. I have noticed that when I charge it, the magsafe 2 connector (the one that actually plugs into the notebook) becomes hot. Sometimes it is so hot that I cannot touch it for more than 4-5 secs. It cools down when the battery reaches 80 percent or so at which point I think it shifts to slow charging. I know that the white plastic box is known to heat up but not sure about this one. Btw my white plastic adaptor does not heat up abnormally, stays warm normally. Should I take it to Apple ?
