Magsafe charger getting really hot My MagSafe connector gets really hot to the point that it burns my skin when I touch it. Everything else is fine, my macbook charges fine and does not heat up that much. Is this normal?
A Mag Safe Adapter that gets warm is normal.  So hot that it burns your skin? Definitely not normal.

This could be a couple things:


Your Power Adapter is failing.  If this is the case, replace it with
a GENUINE Apple Power adapter.
Magsafe DC I/O Board is bad.  From your comments, you said you have a Mid 2015 15" rMBP.  If that is the case, then you will need something like this MagSafe DC Jack
