As far as I'm aware, the Mac version of IE doesn't have the exact same
security holes as it's Windows counterpart. Of course, I'm sure that it
does have some security bugs of it's own, although such bugs are
rarely as widely reported as the security bugs in IE for Windows.
Mind you, if the Mac version of IE had the exact same security holes in
it, as the Windows version, I would have put something more like 95%
in that last line of my previous message, instead of 90%.
Mac versions of IE are usually updated by incremental point upgrades, to
fix any serious bugs, security related or otherwise, as opposed to the way
the Windows versions of IE is updated, with patches and Service Packs.
(UPDATE: Mega security vulnerability in Microsoft products for Macs!
All current versions of Microsoft Windows also affected by this vuln!

Of course, if an estimated 96% of internet users worldwide are using some
version of IE as their primary browser, then at least 90% of internet users
worldwide, are likely to using the Windows versions of IE. The remainder
of that 96% are using IE for Mac, and the HPUX + Solaris variants of Unix.
Mind you, I think the recently quoted 96% usage share for IE could well be
an over-inflated statistic, due to other browsers with UA spoofing facilities,
seeing as Opera spoofs an IE5 UA by default, plus the UAbar add-on you
can now install into Mozilla and Netscape, with IE UA spoofing included.
