Make external optical drive appear identical to internal SuperDrive?
you can get this working by editing a plist file:


open a new Terminal window
edit: /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
Insert mbasd=1 in the &lt;string&gt;&lt;/string&gt; value below the &lt;key&gt;Kernel Flags&lt;/key&gt;. If the string is not empty to begin with (it normally is) or doesn't exist (sometimes happens), then use a space to separate the mbasd=1 from what’s already there or create the entry.


The original solution was from Lukas Zeller's blog here

A Gist is available on GitHub for this change also.
