If you want to install a Windows USB flash drive that can start your Mac computer, you should know that you can use Boot Camp to install a Windows system on your Mac. In fact, Boot Camp also has a feature you may not know-to create Windows that can start Mac to install U disks. In this way, if MM asks you to install Windows for her Mac, you can prepare and install the U disk in advance. First, prepare an ISO image for Windows 7 or a later version, and have at least 8 gb u disk. Then go to the "application" directory on your Mac (tested on OS X Mountain Lion) and find the "utility 』, right-click "Boot Camp assistant" and choose "show Package content"> "Contents" to find "Info. plist. Copy it to the desktop. Edit Info. plist on the desktop. You can open it in any text editor and edit it. Find PreUSBBootSupportedModels and change it to USBBootSupportedModels. In fact, you can remove the Pre and save it. Next, overwrite Info. plist on the desktop to the original location (for security reasons, we recommend that you back up the original Info. plist. The next time you run "Boot Camp assistant", you will find the option to create a USB disk and install the U disk. The next step is very simple. I will not elaborate on it.
