    When you contacted LG what did they have to say?

    Only the Macbookair and the Macmini recognize it.

    In other macs where the superdrive has been taken out there is a command to tell the mac to recognize an external dvd as internal. It is not for the layman...

    There are several articles to change system files with Terminal, but I have used one in two macs that worked perfectly and was the most simple solution.

    1. COPY the following file to a backup place (for example to a backup folder on the desktop):


    so now you have a safe backup of the file;

    2. Then you open the original file with Textedit:

    with the cursor still on the first line, in the Textedit menu File/Find/Find&Replace you simply replace every "internal" into "external" (without the quotes ofcourse); then with /File/Save As you save the file on your desktop (be sure not to overwrite the backup of the original) with the original name, you probably have to give your account password. You cannot save the file in its place because it is running.

    3. Copy the changed file that you made in 2) and overwrite the original file, probably again your account password needs to be given.

    4. Restart the mac, and connect the external dvd player.

    ps: you still have now from both files a backup: the original and the changed one.

    I had my doubts that editing an executable with Textedit was going to work...but having tried it, I stand corrected! I didn't even need to reboot. Awesome!
