Deploy SEP Client problem for Mac

Hi all,

I need to deploy SEP client to MacOS, I know how to install.

But there is a question as follows:

In my enviroment I have 2 SEPM server are named SEP01, SEP02 respectively.

SEP01 (Site 1)- for Windows XP/7 Desktop and MacOS

SEP02 (Site 2)- for Windows server

When I install these servers, I click create new site on SEP01 & SEP02 in order to totally separate them.

So when I install SEP client for MacOS, how the client choose SEP01 or SEP02?
