    The "Brick" part of the charging cable for my mid-2014 MacBook Pro 15" with Retina Display is really hot.

    It's 2 years old but can't say I've ever noticed if it's always been like this or not, is this normal?

    thanks in advance

    Canada, eh!
    Once mine got really hot, I heard a 'pop' and then it died.

    There is protection built in, but how hot is too hot, I don't know.

    A bunch of good info besides the following quote, here --

    thanks for the replies, what I've noticed is it's nowhere near as hot if I disconnect the laptop cooler - I guess this must be drawing a lot of power and making it so hot - does that make any sense?

    Yes'mespecially if you use the cooler because you are also running intensive programs, it is possible for your Mac to lose battery while plugged in when the machine is maxed out, it draws more power than the psu can supply.

    If the cooler is running off of USB there is little doubt your power brick is maxing out and causing it to heat up.

    Does your MacBook get so warm your have to use a cooler?

    sorry for delay in replying but yes it does get very hot, especially when I have dev tools like intellij running, the bit above the F Keys gets red hot
