I’m not sure it’s even possible, but there’s simply not enough of a market for it if it were. No manufacturers have created docks for Thunderbolt 2 that allow a USB-C connection. And there’s no backwards compatibility from USB-C, whether that port offers Thunderbolt 3 or just USB, video, networking, and power. Many display makers advertise their newer monitors as “USB-C” models. ( We published a large FAQ on what you need to connect old displays to newer Macs.) While Mac 911 receives a lot of email about connecting Apple’s old series of displays to new Thunderbolt 3 Macs via USB-C connections, it’s also possible to go the other direction: connect a new “USB-C” monitor to older Macs-so long as the monitor has multiple video ports.
