  2. The list of available drives on the left in Disk Utility window. Choose the external drive you'd like to use for Acronis Bootable Media
  3. Click on the Erase option from the four options available in the main window.
  4. Select the following values for erasing the disk:
    • Format: Mac OS Extended (Journaled)
    • Partition scheme: GUID partition map
  5. Click Erase to format the drive
  6. Re-attempt bootable media creation
