Every MacBook with metal enclosure from the last 15 years had the "buzzing". Quite a few people reported it to Apple, but nothing ever came of that, so Apple doesn't seem to think it's a problem.

It happens with both USB-C charging and MagSafe, but the intensity varies.

I would consider it slightly unpleasant, but have never heard about anyone getting an electric shock.

And it doesn't happen all the time. I have 2 MBPs (one is 7 years old, the other is brand new) and with both I have felt the "buzz"... But not every time. I cannot tell under what circumstances it happens. I have never used chargers/cables other than the Apple ones.

How come mine doesn’t do this? (2020 mbp, standard 2prong charger, often plugged into very old receptacles or extension cords)
