Mac-client Vs OES/Sp2 ?

Hi,

NON mac user here, so Im lost regarding that side of the question,
issue is;
Customer just setup a OES/SP2 server, patched and current.

Would like to connect to it from a Mac.
From what I've read, ifolder.com seemed like the right place to get
the mac-client, but when testing, customer receives message that the
"server is old".

So,, possible that current mac-client 3.7.2 can't connect to OES/Sp2
which is..?...3.7 ??


Anyone knows of a working mac-client or another way to get mac-support

T.i.a..
