Apple laptop charging vibration effect
Turns out I am not going mad - James has felt it too. Interestingly the new MacBook pro is lower frequency than the Air. But both are very noticeable.
If you hold your hand still, you don't feel vibration. lightly brush your hand or fingers over any of the metal surfaces and you feel it.
What is interesting is that this effect is only present if connected to the power (charging).
It is mostly noticeable if you move you hand/fingers over the surface. However, on the Pro just having my arm lightly touching the corner of the case can create quite a noticeable stinging pain. It has bugged me quite a lot while trying to use it today.
WTF is this?
