The last release of Mac OS doesn't have the option to create a bootable USB from Bootcamp like previous versions, and it is a problem because that require uses other tools.
I will show you how you can use UNetbottin to create a bootable USB, it can be used no only for Mac but for Windows and Linux distributions too.
UNetbottin is free software and it is also available for Windows and Linux.
Format USB to FAT32
The USB should be FAT32 or it will not work, you can use Disk Utility and format it, and ensure you select
Master Boot Record in the options:
Check the path name of your USB Disk.
Always in Disk Utility, select the new partition that we created in the previous version, and click on the information button, it will give you the information about the new partition.
You also can use the terminal and the command
diskutil to see the list of drives:
dmgdirectly from the Website.
I prefer to use homebrew to install applications, you can check this article for more information: Installing Applications on Mac with Homebrew:
brew cask install --appdir="/Applications" unetbootin
Makes the USB booteable
Open UNetbottin and you only need select 3 options:
- Diskimage and ISO
- Now we need open the ISO Windows image that is on our computer.
- Select your USB device on UNetbottin.
- Click on the OK, button and wait to the process end it will take a time.
