Part 2: Create Windows 10 Bootable USB Mac Catalina via Terminal

The second method does not involve the installation of a third-party app. Instead, we make use of a pre-built Terminal app on macOS Catalina to create a Windows 10 bootable USB. Terminal app is the equivalent of Command Prompt on Windows. All the tasks are done under text commands. And this may be a little harsh for normal users.

However, this really works for creating Windows 10 bootable USB on Mac Catalina. While there wouldn't be a need to download another app for the process this time, the Windows 10 ISO file is still required to be downloaded in advanced.

Step 1: Navigate to the ''Applications' folder and open Terminal app in 'Utilities' folder.

Step 2: Insert an USB on Mac Catalina and type "diskutil list" command to find the drive letter of plugged USB drive. In the following example, the USB drive name is disk4.

List USB Mac.


Step 3: Now type or copy and paste the following command on the Terminal window to clean and format the USB, also name it as WINDOWS10. In the following command, replace the star at the end of the command with the disk number, at which your desired USB is located:

diskutil eraseDisk MS-DOS "WINDOWS10" GPT disk*

Step 4: Press Enter to run the command. Now, double click the Windows 10 ISO file to mount it on Mac Catalina. You can also mount the ISO file using command:

hdiutil mount ~/path/to/windows10/iso/file

Step 5: You will see the USB name and Windows 10 ISO folder in the root of Volumes folder. And input the following command to copy files from Windows 10 ISO folder to target USB.

cp -rp /Volumes/(Windows 10 folder)/* /Volumes/WINDOWS10/

Volumes in Terminal


Step 6: The last command will copy all files and sub folders to target USB drive. So takes about 20 minutes to complete the copying operation.

Step 7: Unmount the USB and eject from Mac. Now, you can use it for Windows 10 installation or system repair.

Using Terminal is far more complicated than using third-party ISO burning tools but at least it is actionable trick to to createa Windows 10 bootable USB on Mac Catalina. If you were not comfortable with it, then UUByte ISO Editor is your best bet.
