i need some help. i have a mid 2010 27" iMac with a superdrive issue. i had an issue where my 4 year old thought the drive would be a fun place to put a quarter so the drive was replaced about 2 years ago. now since ML update it just reads discs for a few seconds and spits them out. i don't use it often so it hasn't really been an issue but my wife needed to load a program for work and its on a disc, so i'm trying to fix the drive. i've tried everything i can think of, short of replacing the drive for the 3rd time, (yeah 1st was a quarter then 2 discs at same time, the monster is trying to break it i think). Any suggestions? Thanks ---------- i forgot to mention that i have updated to yosemite since. everything else is running fine.
