I have a 2019 16" MacBook Pro running Big Sur (macOS 11.2.3) and just spent a week trying both the MOTU M2 and the Focusrite Scarlett 2i2 (gen 3).
Despite many attempts, including suggestions from MOTU about how to bypass the Big Sur driver installation problem, I have not been able to get the M2 driver installed on Big Sur. Officially, they haven't released a Big Sur driver yet (https://motu.com/en-us/news/motu-and-macos-big-sur/). Without the driver, I can't get my M2 latency on JamKazam below 11ms, which is the same as what I get with no audio interface at all. MOTU has no planned Big Sur driver release date, though when pressed, the guy did guess "weeks rather than months". FWIW.
The 2i2, as described above in another post, doesn't have a macOS driver so it uses CoreAudio for the driver, and with the Focusrite helper file installed (https://support.focusrite.com/hc/en-gb/a.../208736249) I did see JamKazam latency around 5ms (with 96kHz sample size and 1ms frame size).
I successfully installed the M2 driver on a 2015 MacBook Air that I still have on Mojave (macOS 10.14), and without tweaking anything I saw JamKazam latency of 3ms (96KHz sample size and 2.5ms frame size) . But, that computer is very slow and caused me other JK issues. This makes me optimistic that, when they have the M2 Big Sur driver, I might get great latency on my faster mac. So, now I have to decide if I'm willing to wait indefinitely for that, or just go with the Focusrite and be done with it.
I did write to JK suggesting that their "audio interfaces for mac" page (https://jamkazam.freshdesk.com/support/s...6000122513) be updated to specify that the fastest one on the list (the M2) can't currently accomplish that speed with Big Sur macs. Had I known that beforehand I wouldn't have bought it.
