    How hot the macbook pro power supply is supposed to be?
    I never paid any attention to this, until I discovered it by chance!
    I can hardly hold it, while my mbp works!
    I don't know anything about it.
    Is it normal?
    Does everybody's mbp have such hot power supply?
    Are they hot in general, while working?
    Should I stay calm and don't bother?
    I should have some information related to mbp power supply.
    If it is a normal state, I will be ok. But if high temperature means any kind of malfunction(but how can we measure it?), then I should take some action about it.
    Can you please tell me?

    (mbp early 2011, osx ML, but I dont think makes any difference)

    Depends on which part exactly you are talking about? The white block halfway down the power cord does get pretty freakin hot... On the other hand, my Macbook Pro was getting really hot where the magsafe connects to the laptop, and that ended with me replacing a 3 year old battery and the DC-In Charge port.

    I mean the main part of the power supply, the rectangle one.

    My main concern is if this a normal state or not.
    I do not want to have a failure and lost days without my mac in full functionality.

    oh yes the brick does get pretty hot. But I've found my 60w magsafe does not get as hot as my 85w magsafe2.

    So, it seems that it rather a normal state.
    My only worry is to avoid any possible failure, not because of of faulty construction but because of high temperature.

    rest assured its completely normal and wont cause an issue, if it does you have warranty to take care.

    Don't suffocate (i.e. no ventilation) the power adapter, that is all.
