Bad experience

No, this is not normal. Bring it to a genius or return it if still possible.

 

Mains power or static?

 

Static electricity is just build up of electronics charges. This occurs naturally in everything in the environment. However, a static shock can have the potential of killing an electronic device. If this is your problem, then I suggest grounding yourself or start looking for ways to avoid "charging" yourself.

Main power shock means you get electrically shocked when touching the adapter or anything power related of your Mac. If this happens, then you have a faulty Mac.

 

If you are getting a dangerous power voltage then you should carefully unplug the power adapter and not use it again until it is checked or replaced, or the wiring fault in the property corrected.

Static builds up in many areas, in this case it is likely building up on YOU and discharging to earth via your mac, in this case the issue is not likely to be a fault on your Mac.

If in doubt have the Mac electrically checked.

 

Hi,

Try this: your MacBook should have come with a 3-prong plug extension cord for the charger (images attached). Use that. That extension cord has a ground cable in it so it should negate any static shock.

Maybe - but if the static build-up is on HIM the earthed cable just facilitates the discharge to earth
