Hi Everyone! I bought a retina MacBook Pro back in 2012 when they were brand new, and it has been running like a CHAMP ever since. I've had no issues with it at all. Because I have come to depend on this machine increasingly over time, the thought that one day it might up and die on me is a terrifying thought. I recently read the thread about the logic board issues that owners of the 2011 MacBook pros are beginning to have about 3 years after owning it, and I am soon going to cross that mark. I did not buy AppleCare for it, I meant to near the end of my 1 year warranty for it but I completely forgot! So my question is, do you guys have any tips to extending the lifetime of a macbook so that it doesn't have issues any time soon? Or should I start saving up money for the inevitable repair?
