Still nothing for me... I always seem to see the update about 12hrs or more later... not sure if related to this build or not, but all the family devices got jacked up - I got locked out and had to do a password reset - first time since the 80's, and all my email accounts are jacked up. When I try to log into my gmail accounts in mail, it says those paw's are bad too, then hangs when I try to put in the PW... I suspect one of the recent updates jacked up keychain.. Fortunately I can still get in on my phone, but took several hours to just get back into the mac... My daughter is not on the beta release and had the same problem, so I wonder if iCloud is the real problem... hmm. No time to troubleshoot that for apple.
