1) When signing into iMessage, I get an authentication error "an error occured during activation"
2) When attempting to set "unlock Mac with Watch" I get "Your Mac must be signed onto iCloud..you can sign in using iCloud preferences..."
but I am signed in, all the other iCloud stuff works - .i.e iCloud drive, photos, etc...
I have tried signing out and back in -- but still am stymied.
Any suggestions?
