Try restarting the system and press the C key to get it to read the disk which it will fail and kick out. Otherwise you'll need to open up the drive to pull the disk out. Click on the drive image to the right it will lead you to the iFixIt guide on how to open the drive up.

Go under Finder, to the left of the Apple in the upper left hand corner to Preferences. Click on general > CDs DVDs, and iPods. See if the icons shows up on the desktop.

to make the superdrive work on the Macs marked with No from the above listing:

From the Terminal app open a session locate & do the following

sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

enter your password"

this opens:'''

<?xml version=”1.0″ encoding=”UTF-8″?>

<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1...>

<plist version=”1.0″>

<dict>

<key>Kernel Flags</key>

<string></string>

</dict>

</plist>

now add mbasd=1 between the <string><string>

should look like this:

<?xml version=”1.0″ encoding=”UTF-8″?>

<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1...>

<plist version=”1.0″>

<dict>

<key>Kernel Flags</key>

<string>mbasd=1</string>

</dict>

</plist>

save and reboot

Two commands allow you to save the current text in Pico (for the novice) being edited. The CTRL-X and CTRL-O commands save the contents of the editor. The former command exits the editor after saving, while the latter command allows for continued editing after saving.

works on 10.8.5, should work from 10.6, works in 10.9.3, latest Maverics may 17 2014

I have been advised by Apple Care that the Apple USB SuperDrive will not work on any mac products newer than 2012.

Well Barb go to the link I posted directly from Apple and see for yourself. Who you going to believe? Apple or Apple Care or me?

Do the previous instructions not cause a problem with kext signing in the more recent versions of OS X e.g. 10.10.3 where Apple's restrictions mean that any unauthorised kernel edits are blocked and the system will inevitably fail to boot? i.e. is the 'hack' still current?

Sorry, last poster / anon but without this info it would be possible to follow these instructions and screw up the system for the sake of a Superdrive.

Yes! Good point. If you altered the file you will have an issue with Yosemite as kext files now need to be signed. Which is a good thing! Except when you hack the OS to make something work :-{

I have tested this command with Mac OS X.12 (Sierra), the latest Mac OS X so far. It works. Just edit the file and you should be able to use the drive :

<string>mbasd=1</string>

Thanks.

I've tried modifying this file but system doesn't let me save with same name in Terminal. I've disabled System Integrity Protection (SIP) but I still can't save this file. Any suggestions. I have Sierra OS and MacBook Pro12,1 13" Retina Display. Superdrive works if I reboot my Mac, but not if I just connect it. Always has to be rebooted to fully function.

Same problem here with 10.12.6. It won't let me save the edited file.

With 10.12.6 Iʻm having trouble saving the file after editing. It is accepting my passwords ok but the failure occurs with the Save.

Pico tells me:

"Error writing /Library/Preferences/SystemConfiguration/com.apple.Boot.plist"

I tried also with BBedit and when I try to Save it errors out with:

"This file could not be opened for writing, probably because it is in use by another application (MacOS Error code: -54)"

The is ridiculous! Is there any explanation of *why* Apple decided to do this? If they didn't, they might actually *gasp* sell *more* of the "Superdrives" (how many people remember that as a drive that could handle 400K, 800K, *and* 1.4MB disks?)? Okay, probably not, since the Apple one probably costs at least 20% more than a comparable drive.. But still..

High Sierra:

Boot in Safe mode. Then open Terminal and disable SIP

csrutil disable

Then type:

sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

add value “mbasd=1” to string <string></string>

at end it need to look like this:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1...>

<plist version="1.0">

<dict>

        <key>Kernel Flags</key>

        <string>mbasd=1</string>

</dict>

</plist>

Save plist CTRL+O hit Enter and then CTRL+X

Enable SIP

csrutil enable

and reboot in normal mode
