Since beta 4 whenever I try to edit/annotate (signature, text box etc) a document Preview crashes.Anyone have a solution for this?

I was hoping that Beta 3 would solve these issues but they do persist:1)Messages - I cannot sign into Messages with my AppleID - signing in yields "Could not sign in to iMessage. An error occured during activation. Try Again"trying again does not help2) FaceTime - I cannot sign into FaceTime. When I attempt to do so I get this error " This account has no reachable addresses. Please sign into Appleid.apple.com in order to add one" But I clearly have one and all other iCloud functions work. Yes, I have signed out and back in...3) Security - When I attempt to click the unlock with watch button in the security pane I get this message "your Mac must be signed into iCloud - you can sign in using iCloud preferences" but, yes, I am signed inAny suggestions?
