So Its been an ongoing problem with my MacBook Pro Retina, at night time where you rest your arms / palms it feel like theres current coming from them. I have to stop using it for a few seconds then it comes back slowly..... Its been going ongoing for a while, and its an intermittent problem! Have got a telephone call secluded for Monday with Apple. Am I being an idiot about this? Thanks All! EDIT: Use the original / genuine charger that came with the MacBook Pro EDIT 2: http://forums.macrumors.com/showthread.php?t=1625275&highlight=electric+shock Just watched this, the problem is not limited to when charing.
