My USB superdrive is not longer accepting disks after upgrade to El Capitan.

I also tried (despite concerns about going into Root mode) without any success - in my case the plist file came up as read only and I wasn't able to change it, Also I found this forum http://www.hardturm.ch/luz/2011/10/how-to-make-the-macbook-air-superdrive-work-w ith-any-mac/ which says, at the end, that this solution is "Not recommended any more on OS X 10.11 El Capitan!]"

One hoped that today's OSX upgrade would have addressed this but no, it's still deal. I now use an ASUS drive and thats fine. Folks avoid the Apple Superdrive if you have 10.11.

Which model Asus drive? Sounds like the best solution at the moment.

I have the same problem. I found a way to bypass it . When I plug in the superdrive and try to insert a CD it doesn't accept it. So I restart the my laptop (the superdrive remains plugged in) and after the restart everything is ok. Definitely its not a permanent solution so a week ago I contcted Apple's help center, they tried to find a better solution but without success. They told me that they will call me . I believe that this is due to El Capitan . In addition to that FACE TIME its not working at all.

I have the same problem in that my MacBook Pro has no internal optical drive. So I purchased the Apple SuperDrive thinking "Apple product should be good". After upgrading to El Capitan I can only access my SuperDrive if I reboot with it plugged in. Not a great solution - I really don't want to have to restart my computer every time I want to plug in an external hard drive.

This is Apple product talking to Apple product that has ceased working after an OS upgrade. To my way of thinking Apple should be addressing this - not end users trying work arounds that involve meddling with system files.

This is absolutely ridiculous that you cannot simply plug in a USB superdrive to read a DVD and you need to REBOOT for it to work with El Capitan. I mean seriously? Is this 1982 or something? *** Apple?!

Yep, and after the new update Superdrive is still not working. Appalling.

Hi,

I got the same problem and I tried the solution by drwilczur

<<the problem is the lack of record "mbasd = 1" in the system. To solve this problem you need to open the "/Library/Preferences/SystemConfiguration/com.apple.Boot.plist." and edit "apple.Boot.plist" - Text Edit is sufficient.

The key "Kernel Flags" is empty. You must add between start and end string "mbasd = 1" and the problem is resolved.>>

The solution itself is not working for me, but during the procedure I noticed that the drive worked just fine when the csrutil was disabled...

In fact the problem is somehow linked to the SIP for me. For now I'm going to leave it disabled, waiting for a working solution.

Guess their engineers are still working on the problem - 8 months later! I have the same problem!
