After searching the apple website and various fourms I have come to the conclusion that I can only replace the batty in my Late 2011 Macbook Pro if I either: A) Take it into an apple store and have a genius do it. B) Buy a non OEM battery and replace it myself. Are there any other options out there? I would like to buy an OEM battery and replace it myself. And yes, I am more than capable of doing this. Thanks!
