Apple's MacBook Pro computers feature a SuperDrive. The SuperDrive is a disc recorder that is capable of reading and writing both CDs and DVDs. Many different programs depend on the capabilities of the SuperDrive to operate properly. For example, iDVD, included as part of the iLife suite with all new MacBook Pros, requires a functioning SuperDrive to burn its projects to a DVD. If necessary, you can disable the SuperDrive on a MacBook Pro to suspend its functionality.
Click the "Finder" icon in the dock.
Click the MacBook Pro's hard drive in the left column of the window.
Click to navigate to "/System/Library/Extensions."
Drag "IODVDStorageFamily.kext" to an alternative location, such as the root of the hard drive.
Restart the computer. The DVD drive functionality is now disabled.
Move the .kext file back to "/System/Library/Extensions," and then reboot the computer to make the SuperDrive active again.
