I will show you how you can use UNetbootin to create a bootable USB, it can be used no only for Mac but for Windows and Linux distributions too. This is the command to copy the files from the ISO to the USB: cp -rp /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/WINDOWS10/ДЄnd that is all, now you can try boot from the USB. Try to follow the instructions to format the USB in ExFAT, NTFS works for some BIOS). This process could fail if you are using a USB with FAT32 because the file install.win is over 4GB, if this is the case try to open the terminal and copy paste the files from there (no always works.

Go to your USB Command + V paste the files.

Now you only need to copy the files and paste them to the USB. Just double click on the ISO image, MacOS mount the image automatically.

If for some reason it fails, probably is because MacOS still using the USB, just repeat the steps, but if you see a screen similar to above screen is because the operation is successful. In the next screen make sure you select these two options: Select your USB device in the list (not the partition), right click and then click on the Erase option: You need to show all the devices in Disk Utility' before to start the process. In order to boot from the USB, you need to format the USB to ExFAT, you can do it using Disk Utility (it comes with MacOS). Format USB to ExFAT (Under your own risk) The first step for both methods requires to format your USB device to NTFS, this is the default filesystem, alternative you can use ExFAT but the installation could fail. The reason is that I was only using UNetbootin to create the bootable USB, I will leave guide as a second method since it still working, and I will explain to you how you can create the bootable Windows USB without extra software.
