Il Mio Problema
I have an old MacBook that lives in my server closet that provides three AppleTVs and all of our various iDevices with Video/Music. The fan was on its last leg and sounded like a monster was trying to escape the laptop with a hammer.
La Mia Riparazione
Repair went flawlessly thanks to the great directions on iFixit.
Il Mio Consiglio
Nope, follow the guide, smooth sailing.
