        Hangs up at 85% while "Preparing macOS Catalina 10.15.2 Developer Beta...".  Times out with the message "An internet connection is required to install macOS."


        I have connected both wirlessly and wired to a solid 250Mbps connection, but the update times out every time.  The internet connection is open and stable.  Rebooted, ran Disk Utility, but nothing has corrected this hangup.


        Any ideas?
