G Speed Shuttle XL with Thunderbolt 3 -- Hard drive works well with MAC OS that predates Sierra but is recognized on Mac OS Sierra 10.12.6


I tried to contact the phone number for customer support but the line keeps hanging up. This is an urgent matter where I am in a remote location and need assistance ASAP. I need to know the proper firmware and the driver to download for this model so that it can be recognized by my computer. Everything I’ve tried does not work. I have tried disk utility and the computer does not acknowledge that the hard drive is plugged in.
