Enable USB installation in Bootcamp

Before you do anything, make a backup of Info.plist or the whole Boot Camp Assitant app so that you can go back if necessary. Rename it something like "Info old.plist" or "Original Boot Camp Assistant."

Mandatory steps:

• Add your model to DARequiredROMVersions
• Delete the word "Pre" from UEFIModels and add your model
• Delete the word "Pre" from USBBootSupportedModels and add your model
• Remove your model from Win7OnlyModels (if its there)

The last step is to do a code sign. Boot Camp Assitant will not run if it's been edited. You need to resign it. Open Terminal (use spotlight to find it) and type this:


sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app

Good luck!
