So. My mid 2012 retina MacBook Pro has been going surprisingly strong up until now. It still works perfectly fine, but there are 3 major issues that I can't continue to live with: 1. The fans speed up doing very light work. 2. The battery needs to be changed. 3. 3 of the bottom rubber grips are missing. I've asked Apple about the two last points and to fix that it would cost me like 200-300 euros. Due to the fact that Macs are practically non-repairable they said they would have to change the entire "upper and bottom part". Does anyone know what that means on the rMBP(i.e. how much stuff gets changed)? Reason I'm asking is that I'm first trying to figure out if they will fix the fan noise(probably it just needs to be cleaned and new cooling paste(?)) and what would be the next likely point of failure in the future. What would you guys have done?
