I have the last model Macbook before it was discontinued, and was wondering if it's possible to change the CPU? I already upgraded the RAM to maximum capacity and am working on the hard drive next. I understand that the CPU module is soldered onto the motherboard but I've been reading that it can be done; however, you have to exchange quite a few things out but they still need to be compatible with Mac. Can anybody verify this or is it just simply not possible? I already know it voids the warranty and I don't really care about the warranty since I bought this used anyways. Thanks in advance!
