Without more detail it's impossible to say, but my guess would be "no".

MacOS X is a preemptively multitasking, multi-user OS.  The worst that
Twisted and WX should be able to do, even maliciously, is to freeze the
display for a single user.  The worst that a bug should reasonably cause is
to lock up the UI for a single process.

You might have discovered a bug in MacOS X, and you should take it up with
Apple.  Alternately, your Mac hardware might be broken, and Twisted is
interacting with its problems.  If you'd like any further help here, though,
a complete example program would be useful to anyone trying to help you.
