Q80031708 - ARC-8050T3 can not boot from the Apple Thunderbolt 3 machine (New MacBook Pro) machine.

Please update the firmware package to V1.54 2017-08-19 or later and follow the https://support.apple.com/en-us/HT202796 link “How to set up and use an external Mac startup disk”. ARC-8050T3 uses Option ROM firmware. To enhance system security, Mac computers with up-to-date software don’t automatically load Option ROM firmware. As a result, your Mac doesn't see devices that have Option ROM firmware until you load the firmware by pressing “Option-Shift-Command-Period” at the Startup Manager window. Do this each time you want to start up from the ARC-8050T3. Apple macOS 10.12.3 and 10.12.4 have issue to load the devices Option ROM firmware .This issue has been fixed on the macOS 10.12.5 or later version.
