To create a bootable USB drive with macOS, use these steps:

  1. Download and install TransMac on the Windows 10 device.

    Quick note: This is a paid software, but it gives you a 15-day trial, which is more than enough time. (If this works for you and you want to support the developer, you can purchase the full version.)
  2. Connect the USB flash drive. (If you have any data on the flash drive, remember to make a backup, as everything on it will be erased.)

  3. Right-click the TransMac app and select the Run as administrator option.

  4. Click the Run button. (If you’re using the trial version, wait 15 seconds.)

  5. Right-click the USB flash drive, select the Format Disk for Mac option from the left navigation pane.

  6. Click the Yes button to format the drive on the warning message.

  7. Confirm a name for the drive. For example, “macOS bootable USB.”

  8. Click the OK button.

  9. Click the Yes button.
