Snow leopard does not support iCloud services so you will need to enter the account manually (it will work, it just won't auto-setup)
Use these settings
And here is how to get into 'Manual' setup mode.
Well I dont need the @me account. Its there old @mac account I'd like to set up for them. Not sure if mail services still exist with @mac account but the account it self does work for stuff like Messages where I singed them in so we can still do scrren and video sharing as well as it is an apple ID it does still work to so I don't know why I can't get it to work for mail. I even tried sending a message rom my email address to there @mac address and it was rejected. Any thoughts
