usb disc drive problems?

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.

"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.

between <string></string>

so it's gonna be like

<string>mbasd=1</string>"

So where should I type the code ??? I am really bad at it stuff and it is already a miracle that I have found where I have to type the code so please help !"

"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."
