Detection of client OS (Mac)

[plarts]

Is there a tag or a function or a variable to detect what is the client OS,

specifically to know if the client is a Mac ?

Thanks for help.

Play around with variable cgi.http_user_agent and see if it helps.

Yes I will see that way,

I can find "apple" in the user_agent, may be other words ?

I woulld prefer to find out the client OS to be sure.
