In case anyone is interested, I have just released a 'Carbon'
version of MacSpice. The interface has had a major overhaul ,
it runs native (aqua) on Mac OS X and is compatible back to OS 8.6,
and it's still free:

MacSpice started life as a port of Berkeley Spice 3f5 but has since
had a lot of under-the-hood work aimed at making it more robust
and dealing with the many bugs and memory issues that Spice is
famous for. I switch between Macs and Unix and I have put some
effort into making the command line interface nice - it looks
like SIOUX but also it has stuff like command-line editing and
command and file completion.

You're right, the plots are good, but the icons need work.
I'm going to deal with that issue at Christmas.
