Feeling electric current on MacBook Pro M1 with charger plugged in

It seems that the UK version of the Macbook Pro M1 is no longer delivered with a properly grounded extension cable with the charger, but rather with a small UK plug directly connected to the charging block. However, that plug is not grounded.

As a result I'm experiencing an extreme unpleasant electric tingling when touching the Macbook Pro when the charger is connected. It is really an annoying sensation. Considering the price of Euro 3000 for this top of the line product, I find it amazing that Apple saved at this vital point of electric safety.

I have attached the image of the plug coming with the box (bottom) and next to it (above) a wire from an older touch bar model. The latter clearly shows the grounding pins, which are missing in the plug. When using the extension from the older Macbook, the electric current is gone. So it is clearly the missing grounding causing the sensation of electric current on the casing.

Tomorrow I will visit the Apple store, let's see what they have to say. I will update the posting accordingly.

I'm seriously not impressed.

I know you said you don't want to hear it but I recommend as a troubleshooting step that you try another outlet, and/or a different building.

Millions of computers are sold and occasionally we see a post like yours. So the common factor that may be contributing has to be eliminated. If the issue is the adapter design we would see many more posts like yours. This is not to say that your adapter may be not correctly working, but other causes have to be explored and eliminated as well.
