I first noticed “Create a Windows 7 or later version install disk” was missing from Boot Camp Assistant after installing El Capitan. So how to we solve this you ask? Read through the rest of the article to find out.
1. Xcode (can be downloaded and installed from App Store)
2. Free time!
Open Terminal and copy Info.plist file of Boot Camp on your Desktop using below command:
$ cp /Applications/Utilities/Boot\ Camp\ Assistant.app/Contents/Info.plist Desktop/
Right click on the new file Info.plist found on the Desktop and select Open with -> Xcode.
Add new item in section DARequiredROMVersions. The new item value can be found by typing “System Information” in the Spotlight Search (Command + Space).
Add new item in Section PreUSBBootSupportedModels. The new item value can also be found in System Information.
Then edit PreUSBBootSupportedModels and delete the “Pre” to make it become USBBootSupportedModels.
If your MacBook model exists in section Win7OnlyModels, make sure to remove it from there.
Then Save and Exit Xcode.
Final file will look like this:
Change the ownership of the new file to match the original:
$ sudo chown root:wheel Desktop/Info.plist
Above command will ask you to enter the administrator password so make sure you have that.
Reboot in Recovery Mode by having pressed the Command + R buttons while the MacBook starts.
Navigate to Utilities and then Terminal.
Enter below command which will cause to disable System Integrity Protection (SIP) and restart the MacBook:
$ csrutil disable ; reboot
Disabling SIP will allow us to replace the original Info.plist with the modified one.
Once booted back to normal mode, use below command in Terminal to replace the old Info.plist with the modified one.
$ sudo mv Desktop/Info.plist /Applications/Utilities/Boot\ Camp\ Assistant.app/Contents/
Reboot the machine back in Recovery Mode using Command + R keys while booting and enable back the SPI using this command:
$ csrutil enable ; reboot
All finished! Once Boot Camp Assistant launches again, the option “Create a Windows 7 or later version install disk” will appear.
