the easy way is to switch over to using PROCYON LISP. it has its own (almost wholly faithful) version of CLOS (ie it isn't just PCL). in addition, we are building on top of that and should have avaiable by the end of february a LOOPS like environment on top of PROCYON/CLOS. anyway, if you are serious in wanting to use the mac for CLOS work, you need to take a look at the PROCYON stuff. ---jon---
