This tutorial will show you how to create a Windows To Go USB drive that supports Mac computers, then you can run Windows to go on a Mac computer to complete the work that must be done under Windows.

I hav a late 2016 MacBook Pro with MacOS and Windows 10 Pro dual systems installed on it, so far so good, but I only use Windows 10 Pro to play some games that can't be run on MacOS. Now I'm trying to get rid of my Bootcamp installation, because of low space on main SSD drive. I noticed that WinToUSB can install Windows to a USB drive, can the Windows USB drive created by WinToUSB be started from a Mac computer? How do I make it? Could let me know step by step for using your tools.

Yes, the Windows To Go USB drive created by WinToUSB can be started from a Mac computer, but not all Windows To Go USB drive created by WinToUSB can be started from a Mac computer. So we need to understand what causes the WinToUSB USB drive to fail to boot and then we can effectively avoid it.

1. Now All of Apple's computers use Intel CPUs, and Apple selected the Intel-designed Extensible Firmware Interface (EFI) as its BIOS firmware to replace the Open firmware used on the PowerPC architecture. So in order to boot a Mac computer, we have to make sure that the Windows To Go USB drive that we created supports EFI booting.
2. For booting Windows on an (U)EFI-based computer, the Windows version must match the PC architecture, that means a 64-bit (U)EFI-based computer can only boot 64-bit versions of Windows and a 32-bit (U)EFI-based computer can only boot 32-bit versions of Windows. Mac computers use 64-bit Intel CPUs, so make sure you use 64-bit Windows to create Windows To Go.

If you choose "Keep the existing partition scheme", you need to manually prepare the partitions on the USB drive before this step, and here is the user guide on how to manually prepare partitions for Windows To Go.

Tips:
  1. The directory of the additional drivers you specify should only contain drivers that need to be injected into Windows. If this directory contains too many useless files, the process of injecting drivers will become very slow.

Step 9. It takes some time to install. After installation, safely unplug the USB drive from the Windows computer, then connect the USB drive to the Mac computer you want to boot. If you have only the USB-C interface on your Mac computer, you will need to use the USB-C to USB Adapter to connect the USB device to your Mac computer.

Step 10. Power on the Mac computer, and then immediately hold down the Option key, then select the USB drive and press Return to boot from it.

Step 11. Windows normal installation starts up and you have to complete all the installation steps.
