• If the formatting completed successfully, click OK to continue. • Right-click the USB flash drive, and select Restore with Disk Image. • On the warning message, click Yes to confirm the data on the USB drive will be erased. • Click the browse button on the right, locate the.dmg file with the macOS installation files. • Click Open. • Click Yes to create the macOS USB bootable media.
