Is there a pre-built 64b VM on Mac OS that could be made available on 
files.squeak.org or on squeakvm.org? It would benefit many students who 
use Macs to study VMMaker. Cog+ versions are too complex for beginner 

The current workaround is to run it in Ubuntu virtual PC on a Mac, but 
it shouldn't be this hard.

I wonder how other students are coping with this situation.

Yes, but it is not a good option for beginners. Running it off the net 
makes it sluggish and running it off a local server is not trivial (due 
to CORS restrictions).
