Newer Thunderbolt motherboards (and laptops) are Thunderbolt 3 which uses the USB-C type connector. To connect this to Quantum (or other Thunderbolt 2 devices), we recommend using the StarTech Thunderbolt 3 to Thunderbolt 2 Adapter.
We do not recommend using the Apple Thunderbolt 3 to Thunderbolt 2 Adapter on a PC Desktop / Laptop as it may not work.
In our tests using a Gigabyte Motherboard with USB-C, the Apple Adapter worked. However using a late model Dell XPS 13 laptop, the Apple adapter did not work. In both cases, the StarTech Adapter worked.
