Not sure why I wasn’t told till step 7 that I can not replace my optical drive because its soldered together. You can't just use another mac optical drive to replace it, they aren’t the same. Waste of time
Has anyone had problems with hard drives dying after installing? I feel that mine had overheated, because the platers were seized. However I'm only assuming since I replaced the chip board and only got beeping and other platter noises.
