A:AnswerYes it is. I’ve purchased replacements in Amazon for almost the same price and they heat up and meñt the cord. This charger from Best Buy is the real deal.
A:AnswerYes. This will fit all MagSafe models from 2006-2012. In late 2012 MacBook Pro modes they introduced MagSafe-2, which this charger will not fit. Also this will physically fit the 2006-2012 15” MacBook Pro, however they require the 85watt version to power quickly and turn on if the battery has fully discharged.
