I've had people asking me about this, because of the distributed-mac site.

Quoting their web page,

Knowing the nuts on this list (I mean that in the friendliest of ways), 
some of you will run out and buy a copy just to run the DES client... for 
a whole day or two. Then Andrew (2)Meggs will finally release the Mac 
version. Believe me, there's going to be a HUGE difference in speed 
between running the x86 client on a mac in pc emulation mode, and running 
a somewhat-optimized client written FOR the mac.

However, if you already HAVE VirtualPC, then it would be interesting to 
hear what your current speeds are... I know one thing for sure: you're 
cracking more DES keys than I am right now!
