Superdrive inoperative after Mountain Lion upgrade

This may not help everybody, but I've had some success. Tried everything mentioned here -- no luck. Booted from a 10.7 drive and superdrive works fine. Booted to 10.8 and doesn't work again.

Installed Toast on Mountain Lion and now it works fine. If I shutdown or restart I have to launch Toast again to get it to work.

This is definitely a software problem that Apple needs to correct.

Anything in the system.log, via Console.app, when trying to access the SuperDrive? After launching Toast? Those might provide some clues.

I have an old iMac, where burning was unpossible in the last months (Snow Leo).

I have bought a new Mac (M Lion), burned a DVD with the superdrive – worked. THEN I have migrated my data from the iMac – and burning was again unpossible, with the new drive.

I have changed the User on the new Mac. With the other one (both are admins) burning works (via finder).

So I think it is a software problem. But I have no idea where to start. I have looked at apple-i from the disk: In the beginning of the burning much space is needed, I’ve had only 11 GB free. Maybe the disk is too full, when DVDs suddenly can’t be burn?

I’ve always had the same media. It is NOT the media.

At that point, I would probably recommend the nuclear option: take your Library folder, rename it Library-X. Log out and back in. Move back Preferences files and Application Support files for apps that you use frequently, and leave the rest off to the side just in case you need them in the future. :-)

Yes sounds like your disk does not have enough free space. 15% free is roughly the rule of thumb. Try freeing up some space first, and then try.

Good luck

All my apps using invisible files will be happy. 😉 But thanks!

I will try uninstalling Toast first. There is an issue with EyeTV as well, so I need to do a clean install of toast anyway …

Thank you all.

I have burned two CDs from iTunes.

What I have done before:

1. deleted Toast with this

and installed Toast 8 again

2. deleted a few other old things in library/application support and library/preferences:

wondershare

WireTap Pro

ToastIt.plugin

Toast 8 Titanium

Socialite

Roxio Toast Einstellungen

Roxio

NCH Software

Helper

Glims

CrossOver

com.wondershare.helper_compact.plist

com.samsung.Kies.plist

com.roxio.Toast.plist

com.elgato.VideoPlayer.plist

com.bitcartel.radiolover.plist

CocoaJT

Alien Skin

Ableton Live Engine

ABFR Blank Droplet

ABF HotKey

I hope DVD is doing well, too. Will try tomorrow.

Now Toast recognizes EyeTV again, but EyeTV not Toast 😟

DVD is working!

I completely agree with ppapple451. After running my mini on 10.6 for a year and a half without a problem I decided to upgrade to 10.8. I mean . . . with all the benefits Apple was talking about why wouldn't I? Well, they forgot to mention the problems. My Superdrive is fubared. There doesn't seem to be a concesus on how to fix what is obviously a software/firmware issue. I thought that my bluetooth issues on my iPhone with ios 6 was an isolated case of Apple dropping the ball on support. Apparently not.

What can I do if the files com.apple.finder.plist and com.apple.finder.plist.lockfile aren't on my mac?

Can someone pass me those files or do they have to be own of my mac?

They have to be in your user's /Library/Preferences/ folder. However, Apple's hidden it. Click on the Desktop. OPTION-click on the GO menu. and select Library.

Don't have anything scientific to go on but you might also find just as often that the same dead drive still works on a different OS, and not just a non Apple one either.

Just giving a little update here. I was contacted by Apple last month and they acknowledged there was a software issue with the ML upgrade that was causing the drives to stop working. Based on the evidence, that is indisputable, but it is nice they finally admitted to the obvious. They sent me a utility to run on my system that gathered data about the problem and I send them back a nice fat data file. They said they were working on a fix and it would show up in one of the next updates. Fingers crossed for a Oct 2013 fix 🙂

I already checked for hidden files and still couldn't find them, they are literally not there.

Here's a pic

Any suggestions?
