Electricity passes throug the MacBook to me
So, I was charging my MacBook air, its fairly warm, I touch my iMac, I notice my pinky feels tingly. I think its my iMac, freak out, touch it again to no avail. I then proceed to keep my MacBook air on my lap, and type on my apple wired keyboard connected to my iMac via a USB hub that is plugged into the wall. I feel the charge again and I realize the current is coming from my MacBook air.
Should I be worried? Because my iMac and my aluminum keyboard is "grounded" (well the socket this is all plugged into is not grounded... the house is old) and current goes through, does that mean that its the positive line that's live? because if it was neutral or ground it wouldn't go through... And how, if I should, should I approach this to apple?
EDIT: I just put my pinky on a screw on a light switch (So that's definitely grounded) and I definitely feel a current.
EDIT: The plug I was plugging into's ground is not actually grounded.
Esta é uma boa pergunta?

Next time try to use a voltmeter- not your pinky

I re-wired my whole room (Its not in an apartment, but the house is 60 years old) and I made sure all the grounds work (APC's were not complaining of a "Building Wiring Fault") and it doesn't happen anymore. Albet my MacBook air is now charging off of an UPS instead of any ol power strip. Its interesting how some of these plugs are grounded and others aren't....
Also I knew that the MacBook was not receiving any more than what the charger provided, which for the MacBook air chargers, aren't that big because if it did receive any more it would have given me a warning that my charger was going crazy. And since all macs use their alum chasis (if available) as ground I was also wondering what was leaking? and where?
I talk to another friend and he said that all of his alum macs since his G4's did give him this mild shock. Probably his plugs are not connected right...

I have also same problem in my MacBook Air which was just bought on 17 October 2014. When I am using the plug in power socket and I feel some vibration its led and feel like power shock in my hand. Its really not good and why it happened ? this expensive too but work is not good.
