I dont quite understand how to activate the sync for imessage and calendar. Everything else that i wanna work, such as contacts and notes is working; however imessage and calendar is not. What exactly am I doing wrong? Also for the notifications, how do i get twitter notifications? Sorry for asking these questions, i just downloaded mountain lion and im trying to figure everything out and setting up everything that will make things easier. Another question, its very difficult for me to see which apps are currently running in my doc. I cant tell the difference, but i just think there is something different about the light that shows which apps are running. Am i just over analyzing? Plus when i open pages, i dont like how it greets me with this new set up, is there any way around this or do i just need to get used to it?
