Hey I'm going to be taking my week 23 macbook i got sometime late june to the apple store so I can get it repaired by having its logic board and heatsink replaced because it has developed the random shutdown issue. I have no idea how i should take it in. Dont i need to make some sort of apointment with the genius bar? also should i take it in with the origonal packagaging? or do all i need is the macbook itself? how bout power adapter? Advice needed thanks Hopefully this can serve as a good guid for others with the same problem looking to get their macbooks fixed as well.
