2019 MacBook Pro Electrocution

Not a new charger, just a 2-meter cord instead of the small local power plug. The power plug slides off and the accessory cord takes its place on the same power adapter body.

The accessory extension cord has a metal piece inside the adapter-end that conducts building ground to the raised silver lug on the power adapter body, as seen in the picture below. That allows the power adapter body to be grounded, and solves the tingling issue for most users with this complaint:

At this point it's not about what you feel you shouldn't have to do. It's true that the electrical current you feel comes from your Mac not being grounded. Apple no longer includes the extension cable that grounds the MacBook. Those are $20 USD. Connect that cord and your Mac will be grounded. This is nothing new, it's been like this for many years. Some people have better grounded homes. For the rest of us you have to buy the extension cable.

It could be that your house wiring is not grounded correctly. Try using a grounded power cord. If grounding does not correct the issue take/send the computer to an authorized service center for evaluation.

Usual adapter for US/Canada markets has removable 'duck-head' plugin with

optional extension with three-prong grounded plug-in attached. Other markets

with power adapters, use a three-prong adapter directly on Apple charger.

So if you've an Apple power supply equipped with three-prong adapter instead

of these other region 'two-prong toggle' ones, your issue may require different

approach to resolve the irritant electrocution mode. (Most 'shock-effects' are

optional; & require willing user participation, for extreme occurrence usage.)

In some instances, should you have and use 'automatic power regulating' UPS

or backup battery type APC, etc; this may help control quality of power to Mac.

Here is the US version of the grounded AC cord from Apple (there should be a version for each region):

Then make sure your building wiring is correctly grounded.
