I’ve been traveling around the world. It is 50 / 50 of the socket is properly grounded —-anywhere in the world. I get a tingling zap on the wrist when not properly grounded. The charger also gets hot and sparks.

Apple sells a 3-pin extension cable

If you swap in the extension cable head, that does indeed have a ground pin, at least in Australia anyway. The grounding comes from that metal ring that the connector uses as a guide. https://www.apple.com/au/shop/product/mw2n3x/a/power-adapter...

only two prongs of which make it through. Usually the regulation as I understand is that it's fine if you can prove the case can never get in contact with anything electric, for most laptops that's just being made of plastic.

		As has been established in other threads here, the metal button thing the prongs slide onto is an earth connection.

Some heat is normal, but the sparking seems concerning.

That should not happen with a well designed power supply. It sounds like Apple cut some corners "for design reasons", or some shortcut to make it cheaper to manufacture.
