oh crap...I was just reading about this on Digg....looks like a real issue. I'm not updating now my Intel Mac now...the PPC updated fine so far...
but popping speakers would be very annoying...
anyone else have this issue?
I'll just throw a confirmation in that my two PPC macs -- do not seem to be showing this; although both have 10.4.10 but NOT the new Security Update as of yet.
