What is the current recommendation for M1 Mac users?
Officially there is none.
Whonix on Mac M1 (ARM) - User Support (still unsupported at time of writing) is all that ever happened and should that change that forum thread will certainly be updated.
That is actually off-topic in this forum since unspecific to Whonix and best discussed in general Linux or even general computer support places. → Potential Solutions Beyond Whonix!
