I just got a macbook with a combo drive is it possible to change the combo drive and get a superdrive installed instead. (doing it myself or third party install it). I have an external dvd burner but I just think that it would be better if i had a built in one. Another question is there a way i can replace a screen on a macbook without apple knowing or through a third party with out voiding the applecare warranty. Is there a safe way to do it without them finding out? Where can i find a place to replace my screen for cheap. Just switch from the PC and trying to learn the way of the mac. Thanks in advance for all response.
