How can I avoid my MacBook Pro giving me minor shocks? The aluminum Macbook Pro gives a mild shock when connected to a wall socket and charging. It only happens when I'm, for example, not wearing shoes or slippers and my feet are resting on the ground (i.e. by body is acting as a conductor).
I contacted apple and I was told to perform the following steps:

Shutdown

hold ⇧+ctrl+⌥+power for 10 seconds

wait 30 seconds then hold ⇧+ctrl+⌥+R+power (Let the Mac reboot three times with that apple tone, then let go. The Mac reboots again.)


This did not fix the problem and I was not told what these steps were supposed to do. They have asked me to purchase a three pin version of the adapter and see if that fixes my
problem.
My last MacBook Pro was giving pretty severe jolts towards end of life. Hence a bit concerned.
Question

Has anyone here experienced such a problem?

Is anyone aware of what the above sequence of steps supposed to do?

Also, will this damage the Macbook in some way?
The solution for me was to use the adapter with a three pin extension cord.
Then your notebook is grounded, and no more charges stay on the cover that shock you. :-).
About steps 1-3
In steps 1 and 2, you reset the System Management Controller (SMC Reset) on a Mac that has a battery, which you should not remove on your own. The SMC manages hardware conditions related to temperatures and power consumption. You may also be interested in the question: When should I reset the SMC on a Mac?.
I'm not aware of the shortcut you performed in step 3.
