[Web4lib] Coding for IE5.2 on a Mac?

[Nancy E. Sosna Bohm]

I've been asked to replicate a site I did for one educational institution
with different colors and content for a sister institution. Both websites
include Library pages/sites, so I think this is relevant to this list.
The Director of Communications at the sister institution uses a Mac with
IE5.2.
One of the "Suckerfish" styled menus evidentally doesn't work in IE5.2 on a
Mac.
I thought IE on Mac was obsolete.
Is this a browser for which many on this list code?

Thank you in advance for your replies,
