Rekordbox 6 officially supports MacOS from 10.14 (Mojave). DVS control might work with Sierra but there is no guarantee this will be without issues. And there will be no support for it.
On Windows 11 it's officially supported.
If you want a safe bet you could try an older version of Rekordbox (5.8.x) that has official Sierra compatibility.
Please remember in both cases DVS is not unlocked out of the box. If you use it with Rekordbox 6 you will need a subscription. If you use it with Rekordbox 5.8.x) you will need the DVS Plus Pack to unlock it.
Any reason MacOS is still on Sierra?
