After some research online this seems to be quite a common occurrence, however there also seems not to be any consensus on the cause.
With a Macbook Pro 13 (2017), I’m getting it quite a lot. It feels like electricity almost and tends to make my fingers sensitive to other things as well, almost like they’re bruised or raw. I’ve tried different sitting positions, using different fingers, alternating hands, but nothing seems to stop it.
Has there been any study done about this or does anyone know if the cause has been identified?
As a side note, if it’s got something to do with the conductivity of the trackpad, this could also explain why my speakers, on two different Macbooks, occasionally emit a crackle of static.
