Just a note for People who have had iMessage and iCloud working, but stops syncing, or if its a new install and you recover your account data, I find that if you go into Activity monitor, and force quit, Cloudd, Bird, and Photos, and Photos helper. This start everything syncing again, and iMessage starts to work again.

In my case, you just have to login into Icloud again. If you have two factor auth, you will received a notification about it. After, you have to go to Settings, Messages, and Text Message Forwarding in your iPhone/iPad. Review the devices, if you did an upgrade you will probably see the old devices connected, remove that one and enable the new one. That should do it.
