  • Connect your USB drive into the Windows computer
  • Go to This PC > right click on your USB > Format NTFS.
  • Open cmd with administrator and type in list disk > hit Enter
  • Note the list disk of your USB. It’s usually at the bottom.

  • Once done, open the software from Desktop or Start menu and run it as administrator. For free version, you need to wait for 15 seconds and click on Run.
  • Select your USB drive, right click on it and choose Restore with Disk Image
  • You will be prompted that all the data in your USB will be lost.
  • Click on Disk Image to restore and browse to the DMG file you downloaded earlier.
  • Click on OK. If you see a warning prompt, simply choose Yes
  • Wait for Transmac to do its leftover tasks. Once you see a Restore Completed popup, it means you have successfully created a bootable macOS USB drive.
