USB connectivity question

Hi! I just got a new MacBook Air (the one with only USB type C ports) but my recording interfaces all use a USB type B cables. Can anyone recommend a replacement cable (or adapter, but preferably a single cable with correct jacks at either end) that will transfer data between interface and computer correctly? Interfaces are a Focusrite Scarlett 2i2 and Behringer UMC1820, FYI. Thanks!
