So i took my macbook pro mid 2012 to get looked at cause it was shutting down when held a certain way. Also the screen would freeze but sound would keep playing on the background. They told me there was a problem with the logic board and that it needed repair. However they refuse to repair without also doing a "desoxidation" which is their fancy term for cleaning, and replacing the thermal paste. Now this service alone costs THE SAME as repairing the logic board, and they refuse to repair it without replacing the thermal paste. My question is, is this as irrelevant as I think it is? Because i truly don't think the thermal paste has any bearing in the board's malfunction, they're literally just trying to cash grab me. Sadly they are also one of the very few if not the only trustworthy places to repair a mac that's out of its warranty, so I am not very happy, but perhaps im wrong and this is ~ absolutely ~ necessary. Ty in advance
