If you want to go the thunderbolt route a cable such as this one should work. There are similar cables for USB 2 and USB 3. I haven't used the thunderbolt port for that kind of recording but have used USB. Either protocol should be fast enough for there not to be much/if any latency issues.Mac air,2018, no mic inout but USB and thunderbolt 2...can I use thun2 somehow???
