The tingling you may feel is absolutely normal. Most devices (Mac minis and MacBooks while connected to the charger) don‘t even connect to PE (only 2 connectors on the plug).
The tingling comes from some leakage across the transformer isolated primary/secondary but is so small that it’s not dangerous.
That’s also completely unrelated to static discharges that zap you once you touch something that can equalize the potential
- kube-system 6y agoThe post on the AC adapter (that the duckhead or extension cable slots into) is earthed, and some adapters (other than the 2 prong US duckhead) continue this to the building ground. The US extension cable is earthed, and I believe some duckheads in other countries are as well. The power adapters that were in use for mac desktops during the time period that the person I am replying to was referring to were earthed. https://th.bing.com/th/id/OIP.vmVNrqGAR3raMcey5fAXUQHaE6 https://th.bing.com/th/id/OIP.vmVNrqGAR3raMcey5fAXUQHaE6 Although you are correct in cases where the device is not earthed.
