Have I missed something?

I read the three detailed articles provided by a previous poster, but could not see any reference to whether or not one can "opt out" of iCloud in MOUNTAIN LION.

Therefore, the question remains: Does one have to sign up for and use iCloud in order to run MOUNTAIN LION OSX 10.8?

P.S. Apart from privacy/security issues with the concept of iCloud, one would not be able to run MOUNTAIN LION without an internet connection (to iCloud) . . . if the reality is that one is required to use iCloud when the computer is turned on. Of course, that does not make sense to me unless APPLE is designing its software to force users to tap into iCloud as their new way of "doing business."

Note: I do not use iCloud, any social networks or any IOS devices with my computer.


Many thanks,
