Q: superdrive not loading discs after upgrading to el capitan

After upgrading to el capitan, my superdrive no longer loads discs into the tray.

I have turned off and restarted my mac and no improvement.

 

Any further suggestions?

MacBook Pro with Retina display, OS X El Capitan (10.11)

    Disabling the SIP was the thing that allowed me to save the changes to the plist file. Thanks for the help.

    I was able to edit com.apple.Boot.plist, although I had to make a copy of the file and then move it back into the SystemConfiguration directory replacing the original file and using my admin password to authenticate. But it still did not allow me to use my USB SuperDrive. SIP was disabled, and hidden files were unhidden. Other thoughts are welcome. Thanks.

    I wasn't even able to edit the Plist despite disabling the SIP. Since EC my superdrive is largely useless. I guess we await someone at Apple to notice this bug.

    I wasn't able to directly edit the .plist file, but I could save my edits in a copy and then move it back to the directory. However, this didn't restore my SuperDrive function unless it was connected at the time of boot.

     

    I've sent logs to Apple several times and been working with their tech team to try to solve this problem. They first thought that there was an issue with Logitech Control Center since it writes to a system file. Completely uninstalling LCC didn't help. They then thought there was a problem with Toast Titanium. Again, uninstalling didn't solve the problem. I'm thinking that perhaps a clean install and then reloading all my software and documents might be the only answer.

    One more observation. When I connect my USB SuperDrive, it makes a soft "clunk" sound as though it was trying to pull in the disk - which it still won't do. I'm wondering if it think that there already is a disk inside. When it's connected at boot, there's no such sound.

    Hi

     

    for me only work if I do this:

     

    1) With the macbook (turned on) in the finder plug the superdrive;

    2) Restart the Macbook with the superdrive Plugged In

    3) When the macbook restarted go to finder and click on devices.

     

    But I think that Apple can solve this. It's ridiculous  do this to access my drive.

    adding mbasd=1 does work.
    I got around the problem of not being able to edit the
    com.apple.Boot.plist file as follows.

    I started up off a backup.
    Now using sudo, there was no problem editing the file.
    Then I restarted with the el capitan system and
    my superdrive worked again.

    Really idiotic that they would break this and not even fix it by 11.11.1

    Hi, just wondering how exactly to add mbasd=1?

     

    Untouched, what I see in the plist file near "Kernel Flags" is:

    ...

    <dict>

         <key>Kernel Flags</key>

         <string></strings>

    </dict>

    </plists>

     

    Should I add mbasd = 1 like this:

    ...

    <dict>

         <key>Kernel Flags</key>

         mbasd = 1

         <string></strings>

    </dict>

    </plists>

     

    If not, how?

    No,  it should in between the two strings.

     

    <string>mbasd=1</string>

    Excellent. Rebooting with the Superdrive connected helped solve my issue! Thanks iPadHeadache!

    I have my iMAC with built in optical drive. Since upgraded to El Capitan following problemes occured:

    1. My localhost (MAMP) - I can't write, copy, move, delete anything in "Sites" folder. I Also have still the old "Webfolder", but MAMP doesn't mount it as a localhost.

    2. After a couple of tries I was able to burn a data DVD. But I am not able to check or read it, because after about 15 seconds of reading the disk is ejected.

     

    I tried to downgrade back to Yosemite, but even avter restoring from TimeMachine, again only El Capitan is installed.

    I'm sure this will apply to very few people, but in my case the culprit was Blackberry device manager. Installed it a long time ago for work, and its device manager services must have been interfering with the drive under El Capitan.

     

    If you run activity monitor and look for BBDaemon (and I think BB Device Manager - can't recall and I've deleted it now), then this could be your issue. In spotlight, search for Blackberry and run the Blackberry Device Manager uninstall. The uninstall makes you reboot, and after that the drive worked for me.

    I tried everything suggested in this thread and nothing worked. I also tried remote disc from another Mac and that mounted the disc, but the installer wouldn't run. It claimed the install.app was damaged or incomplete.

    I was making an image of the disc that I was going to copy to an external HD to install from, but I tried one more thing. I dug up a different superdrive and the disc mounted and installer ran.

     

    Bad superdrive? could it be a firmware/REV issue?

    Anyway, the second superdrive fixed our problem.
