I have dozens of the Keyspan units in production with no problems
anywhere, with a wide range of various versions of OSX. I have not had
any systems that needed the 64-bit driver yet, so I have yet to see
that in action. But I keep my desktop & laptop up-to-date and have
zero issues. The Keyspan units seem rock-solid as ever to me. 

The PL2303 dongles work just fine with the proper driver (ie. the
SF.net one is what I usually get).

The new-school Cisco USB console connection just works on a Mac as
well without loading drivers (although who knows, maybe something old
I picked up once long ago handled the connection). I thought that was
pretty slick (although I don't have that long of mini-USB cables, have
to get some longer ones of those).
