#2I've run across this before - once I measured the shell of my MBP at 90 volts DC.
If you don't have access to a 3-pin charger, you could always use a separate earthing setup, such as an antistatic mat: https://en.wikipedia.org/wiki/Antistatic_device#Antistatic_m...

#3Don't use Macs but I'm surprised Apple apparently didn't give an earthed power adapter by default on a metal skin product. This seems like negligence.
Now that I think about it, my iPad's the same when charging.

#4I never had that issue in the US (even when using a two-holed outlet), but I had that problem when I was visiting Israel. So it seems to only be an issue when using 220 volts and not a proper ground connection.

There's also a good chance that, at least in part due to Apple's greed and extravagant prices for chargers / fragile power cords, many people are using knockoff chargers and don't know it. See also Amazon happily selling knockoffs as real -- Apple claims 90% of chargers it recently bought on Amazon are fake and is suing the supplier, though unfortunately is not suing Amazon [1], which might help Amazon find the will to stop people selling fakes.

Same here. I've only had the issue in Thailand. No shocks at all in the US.

They do give one by default, but you can disconnect it if you so choose.
FWIW, I have never had a problem using the two pronged plug in the US. It's interesting to see all this preexisting problems with MacBooks surfacing after the recent release of the MBP

#8I have this problem in India. I suspected the mains was dodgy, because during the many power outages i never got the shocks when on UPS.
I got a multimeter and measured. The neutral was 70V and the phase 300ish. So the difference was roughly 230V but a switched power adapter would make this hover around 70 too (I believe an old coil based would probably been fine).
The Indian electrician didn't understand my problem because his only tool was a regular bulb with two exposed wires that he jammed into the socket.
"Look sir, light, power working"
sigh.

I have this problem every winter. With my Macbbok it was the worst, it even caused the trackpad to stop functioning once, but it has also happened to some of my other devices as well.
It's happened so often to me that I've trained myself to touch something to discharge the static before touching my equipment.

I get it in my apartment (I live in the U.S.) which is brand new with 3 prong sockets if I have my feet on the ground (concrete floor) while roughing the laptop.
I've experienced it a few more times at different peoples houses as well.
