    I finally made the switch today. i brought my first mac machine. im loving it. but i notice there is a slight vibration when charging it. my ipad also does the same while charging.

    does anyone have any idea what the cause of it is? and will the vibration damage my macbook pro?

    If you are in California, it might just mean you are having an earthquake ;-)

    Electricity does make some vibrational energy, you will hear a high pitched electronic "whine" sometimes, but I have never felt my iPad or MacBook physically MOVE like that.

    What you are getting is a slight voltage through the device...I'm guessing you only notice this when you touch the edges? The same thing happens when my iPad is charging, can't tell with my MBP or MBA as they are both in full Speck cases, but I'm guessing they would be the same. It's nothing to worry about.

    The sensation you're getting is due to poor grounding. The MBP is very sensitive to the lack of proper electrical grounding, in some cases it's something you have to deal with (as in using electricity in a country that doesn't offer grounding on their outlets) however in the US, you can swap your 2 prong end to the long 3 prong grounded extension.

    Happens on my iphone all the time. Its not really a vibration so much as it is this slight tingling feeling when touching it, though I can see how that could be thought of as a Vibration... and as others have said its just electricity. Doesn't hurt anything as far as I'm aware.

    I swapped my iPad 3 prong pin into my MagSafe adapter and still the tingly feeling. So it must be my outlets in my house. Was kinda hoping the grounded plug would work.
