Q80021708 - Since updating to macOS Sierra, ARC-8050T2 cannot boot from the Apple Thunderbolt 3 machine using Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

Apple macOS 10.12.3 and 10.12.4 have issue to load the devices Option ROM firmware by pressing “Option-Shift-Command-Period” at the Startup Manager window. As a result, your Mac doesn't see ARC-8050T2 that has Option ROM firmware. This issue has been fixed on the macOS 10.12.5 or later version.
