Q: optical drive not working after upgrade to yosemite

Okay, none of these fixes are working for mine. There is no disc stuck in it. I can't get a disc in further than less than halfway. I don't need a firmware update (because I've downloaded it and it won't run). Ejecting in terminal causes the drive to make a small noise, but no spinning or waking up.

Was anyone able to see their drive in Disk Utility when it was non-functioning? I'm wondering if mine is just dead.

Holding down C or eject while rebooting did nothing either.

Help.

Mine is completely dead and it was brand new. I bought a new iMac in October 2015 along with the superdrive. Plugged it in and wouldn't accept any disc, just kept spitting it back out. Tried all the solutions other people have suggested and none of has worked! Beyond p*ssed because I could have saved myself £65 if I knew it wasn't do anything.

My iMac is on Yosemite, haven't downgraded or upgraded, nor do I plan to because I heard El Capitan is crap. I've located my superdrive in the disk utility but it comes up grey. You can click on it but it just tells you how to erase a rewritable CD/DVD so I can write on it again but I don't have any CDs/DVDs on me that I can do this on since I'm away from home. Only options I have at the top of the disk utility window are "info" and "burn". Other options have been greyed out.

I'm having the same problem with my mid 2009 13" mac book pro. i wonder if it has anything to do with the fact that i also upgraded the hard drive to a SSD. 

tried resetting SMC

tried terminal command "drutil eject internal"
