One of the first problems Lightyear had to solve (and it was not trivial) was the way messages were passed between big and little endian systems: this has been solved, but maybe it\'s not in CVS, and this could explain your problems when logging in. Another much bigger problem relies in how Apple implemented OpenGL in its OSX OS: this implementation caused PS to run incredibly slow no matter what you did. Our MAC release is on hold because we\'re waiting for Apple to release their fixes to this problem, which, according to them, should not be too much far away.
