I updated to B5 two days ago and Time Machine appears to be making updates but the Latest Backup Date has not changed in two days. When I enter Time Machine, I see what appears to be recent backups and I can restore files. When I Command-R on startup and use Disk Utility, the most recent restore backup is 2 days old. I've filed a report with Apple but wonder if anyone else is having any issues with Time Machine. Thanks.
