Personal Security Manager 2 is out.
Wednesday September 6th, 2000
According to that page, "A Macintosh binary will be available from this page soon."
I don't know how long that message has been there.
Of course, in reality, they don't need it "yesterday" - they need it in time for the actual release (beta and final) of Netscape 6 on Mac. Until then it's irrelevant anyway (although obviously from a practical perspective, for those few who *are* testing/playing with Mozilla on Mac it's much-needed).
