Until a few weeks ago I was using a UM2 with a MacBook Air. I found it worked reliably with a 2ms buffer size and a sample rare of 48kHz. The interface latency was 11.5ms, which was not great, but was usable. I switched to using a Focusrite interface which has a better latency—mainly because another band member had one that he no longer wanted!
