From what I gathered about the startech adapter, it only works for connecting a tbolt 1/2 device to a tbolt 3 host.
I pre-ordered a razer core, and wanted to connect it to my mid-2011 mac mini, which has tbolt 1.
So I need an adapter that can connect a tbolt 3 device to a tbolt 1/2 host, and I cannot find any such adapter anywhere.
The akitio adapter will not do this either: https://www.akitio.com/adapters/t3t
In the meanwhile I'm cancelling my order for the core, and will wait until there is something that allows this to work.
