  1. I’m already backing up my entire computer and about to do a complete reformat. I can’t Wait! The only way to install any new update, is to do a complete clean install and manually put everything back. Don’t use time machine to restore stuff back. Just make a new Time Machine Backup. It’s always better that way.

  2. “Fixes an issue in which an incorrect alert message could appear stating that a backup volume does not have enough free space.”

    Time Machine is supposed to delete the oldest backups to make room for new backups when the disk gets full—which means that the message “not enough free space” should never appear unless there is not enough space on the backup drive for the very first Time Machine backup.
