New 2017 Macbook Pro 15 Inch giving me static electric shock. Is it normal?

I don’t think you understood the existing discussion. The tingle is normal for these units (like with most switching power supplies) when used without a real earth ground. So no, replacing the adapter won’t change anything, because it’s not malfunctioning. Nor is the MacBook faulty. If the tingling bothers you, get the 3-pin power cord and make sure your outlet is properly grounded.
