I use version 2.0 and like it alot.  It runs under MultiFinder, handles 
objects, arrays, streams, closures, macros and so on.  Best of all, it's free
and the source code is obtainable.

It lacks many Common Lisp functions such as multiple-value-bind, values, and
with-open-file, but hey, these are convenience functions anyway, right?

The moral is, if you're going to write it yourself, XLISP is great!  But
don't expect to download AI programs that run in Lucid's Lisp or KCL and run
them on your Mac.
