I am definitely using the x86_64 executable. I was curious to see if I 
just moved things across to the new machine if they would run better, 
worse or the same. Didn't know at the time that there was a new vm - 
searched recent mailing lists and did not see any indication of one. Now 
that I have one for apple silicon, I will see how it goes. BTW, does a 
6.0 vm run a 5.3 image OK?

As for following OpenSmalltalk-vm, that's a bit outside my comfort zone, 
but thanks for the tip.
