Agree with post above.
I wouldn't buy Apple's superdrive.
Instead, buy an external USB drive that has CD/DVD/BluRay -and- M-DISC capabilities. Will cost only a little more than an Apple drive, but have the ability to do much more.
Samsung makes a very nice drive in their "506" series.
Be aware it's a "tray loading" device -- which I prefer over "slot loaders"...
