Notifications has many of my favorite Apps in it, however, Time Machine is conspicuously absent.

I read here that it should be showing:

System notifications System alerts with updates about your battery, Time Machine backups, and ejected disks appear as notifications, so you can easily spot them with the rest of your notifications.

How do I add Time Machine to the list?

  • Do you mean that Time Machine doesn't show up in the list of apps under System Preferences > Notifications, or that no notifications from Time Machine ever appear? (In my experience, Time Machine only notifies me when a backup hasn't happened for many days...) – Dan J Mar 20 '14 at 22:08
  • Correct, it does not show up in the list of apps under System Preferences > Notifications. I have seen notifications on another computer, running Mavericks, that pops up a notice when a backup is successfully completed. – fmz Mar 20 '14 at 22:30

You don't need to add Time Machine to the list. Along with all other OS X system notifications, they are shown in Notification Center without any user intervention required to activate them. Conversely, you can't disable them either. This is the same with battery notifications, disk ejection notifications, etc.

If you want to disable Time Machine notifications, set the flags value for _SYSTEM_CENTER_:com.apple.TMHelperAgent in the app_info table in ~/Library/Application Support/NotificationCenter/<udid>.db to 12609 or 13639.

If you want to customise it further, change one of the other entries for Notification Center, then read the flags value for that app and save it as the flags value for TMHelperAgent.

  • Hi GR, please see my note above. Is there any way to modify what notices you get for Time Machine? – fmz Mar 20 '14 at 22:31
  • @fmz Not really, but see my edit – grg Mar 20 '14 at 22:35
  • I see 535 value for flags in Yosemite. What value should I set? – AlKozin Oct 30 '14 at 7:29
  • @AlKozin Set the value depending on what type of notifications you want. I haven't tried this on Yosemite but the procedure should be the same—set the notification settings for any other app, then copy the flags value for that app to Time Machine. – grg Oct 30 '14 at 7:54
  • @grgarside Thanks! Don't think about solution from that angle. – AlKozin Oct 30 '14 at 8:26

To disable Time Machine notifications on Yosemite, first find the Notification Center database by running:

cd `getconf DARWIN_USER_DIR`/com.apple.notificationcenter/db

You'll end up in a directory containing a SQLite database called db. In this database's app_info table, set the flags value for _SYSTEM_CENTER_:com.apple.TMHelperAgent to 12609.
