Question here is I have an MBP with this IDs: Model id : MacBookPro9,2 and apple model number : A1278. It is MacBook Pro mid 2012 with I5 right now. I am thinking if there is any chance that I can upgrade/swap this logic board for better one but not for that what is used in other mid 2012 with I7 as it is only dual-core. Is there any chance that I can fit some logic board with quad-core I7 processor? Somewhere I have read that some logic board from 2015 can fit into it and it is quad-core.
