Hi

Is the current leak a common problem for macbook charger? i tested few locations other than my house all has the current leaking (kind of like small tingle/vibration)

The default stock charger does not have 3rd pin for grounding, i am not sure what else can i do...

Its a common issue for all Aluminium unibody Macs... Everyone will face this issue unless you have a 3rd ground pin for your plug. Either you live with it as it doesnt really harm you or purchase 3 pin plug

I see, thanks for the info
but it does not always happen though... Sometimes the same socket will leak but sometimes does not

just use the 3 pin plug and you should be ok.

Yes, happen to me since day 1 bought it. Use the other 3 pin cable (long cable), problem solved

This guy?

Oh I didnt know about that

Anyway I notice the tingling sensation is worst when the battery if fully charged. When it's charging, still not too bad.

Stop using the short 3-pin/ 2-pin plug head and use the long extension came with the Mac you should be fine. If still have current shock issue, check your power outlet, lastly send your Mac for warranty.
