The internal optical drive is no longer reading disc so I bought a USB Superdrive not knowing it wasn't compatible with my computer. I know there are easy modifications out there to make it work but I can't find the files on my computer to modify. The most common and easiest fix is to modify the com.apple.boot.plist file but I cannot find it in mountain lion. Can anyone help?

Thanks!

not going to work

the external superdrive for 10.8.2 does not work..AppleCare does not know why so don't bother. I have the same issue. Its the .2 Update. U cannot get a clean copy of 10.8 anymore as Apple added the updates if you want to reinstall the OS.

RE: nvram...

Hi,

You might try setting the nvram boot arguments yourself using:

sudo nvram boot-args="mbasd=1"
<reboot the MBP>

to see if this works under 10.8.2. I haven't tried this myself since I no longer have the machine to test this on, but I do know that it worked on a MBP under 10.8.1 when I did own that machine.

Good luck,
Switon
