At the 48,000Hz setting I got the Audio Latency down to 6.3ms. At the 192,000 clock (sample rate?) it resulted in very high latency - 35ms. Then did the same as you did, adjusting the Frame Size to the 1ms experimental option. The other variable I've just been playing with is the clock rate - go to Applications-Utilities-AudioMidiSetup - and I change this from the default of 192,000 down to 48,000Hz.

The result is that I can't get the 4.0 ms audio latency that Hans reports on his Windows machine. I bit the bullet and bought the Behringer UMC404HD (202 not available anymore & I hope sometime to do 4 part simultaneous recording). Let me know if I can help.Hi Moose and Hans - thanks for all the good information. With one mic you probably don’t need 4 inputs for JK? The biggest advantage to the 404 is the number of inputs. I’m pretty sure the 202, and 204 would do about the same. Changing the frame size,( I think it was that setting name)to 1ms experimental and I get 7.4.

I run an older MacBook Air with the UMC 404HD On initial setup, latency will be around 10 with the core audio.
