macOS USB Bootable Installer

If you want to make a bootable USB for macOS, you will need to download the installation package from the Apple App Store.

Make sure your bootable USB flash drive is erased and formatted.

  1. Open Disk Utility found in the Utilities folder, select the USB flash drive in the sidebar, click the “Erase” button, and then format it.
  2. Name the USB flash drive to “Untitled” if it isn’t already assigned.

After its erased and formatted you will need to launch the Terminal application found in the Utilities folder.

Once it’s started Copy and Paste the following into the Terminal application:

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled/ --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction

Let the installer files copy and complete. Once finished reboot and boot off the USB to start the installation.

Shuttle DS81 Sophos UTM Install Fix

I’ve found installing various Linux/Firewall distributions like Sophos UTM end up getting stuck during install on the Shuttle DS81. After continuous research, I finally discovered it was not because it had a built-in memory card reader or HDMI input. It is actually due to the lack of VGA support.

Adding the VGA port accessory (Part number PVG01) available from Shuttle fixed the issue. The VGA output replaces one of the two available COM ports on the back. The VGA port accessory works on the following models:

  • XH81
  • XH81V
  • DS81
  • DS81L
  • DS81C
  • DS87
It appears other folks have encountered the same issue:
