Facetime/iMessage don't work when login iCloud
Hello,
I Have one problem with my Macbook Pro Retina Display 13'' Middle 2014.
When i login in the iCloud, my FaceTime and iMessage became slowly or sometimes don't work. I really don't know what's happening but when i log off the iCloud or remove the synchronization of contacts, reminders and notes, the problem stop and the FaceTime and iMessage start work again.
Does someone have the same problem?
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
