Why are Time Machine backups not visible?

No Time Machine backups showing up on the external hard drive can be caused by a lot of reasons. Here we summarized the common ones.

  • The initial backup is still going on. Usually, only Time Machine finishes a backup, then it will list on the external drive.
  • The Time Machine external hard drive has connection issues and hasn't been correctly recognized by your Mac.
  • The backups on the Time Machine disk are accidentally hidden.
  • The Time Machine backup disk is a network drive and the network connection is poor.
  • The backups on the drive have been accidentally deleted.
  • The Time Machine backup drive has some errors.
  • The disk driver of the Time Machine backup disk is outdated.

Time Machine backups are not visible, how to show them up?

If you start up a Time Machine backup just now, please wait for the initial backup to complete. Or else, it won't appear on the backup disk.

If you have backed up files to the Time Machine backup disk before but don't see any backups after connecting it to your Mac this time, things could be much tougher. To show the Time Machine backups that are not visible on your Mac, follow the ways in this part.

Manually mount the Time Machine backup disk

Maybe you've enabled encrypting the backups when setting the Time Machine external drive. Thus, every time your Mac detects the Time Machine disk, a popup will appear to require you to enter the password to unlock the drive.

If you accidentally ignore unlocking the Time Machine disk, it won't mount. Thus, you can't see the Time Machine backup drive show up on the Finder sidebar and the desktop.

To fix that, you need to:

  1. Go to Disk Utility.
  2. Select the Backups of (Your device name) volume and then click the Mount button. 
    mount Time Machine backup drive
  3. Enter your password to unlock the drive and let it be mounted. 
    unlock the Time Machine backup disk to let it mount

Then, the Time Machine backup drive and backups on it will be visible.

Reconnect the Time Machine external hard drive

If you don't connect the external hard drive to your Mac properly, macOS may fail to recognize and mount it correctly. Then, you fail to see the files on the Time Machine backup drive.

You can eject the external drive and then slowly and tightly connect it to your Mac. After that, check if the backups pop up on the external drive.

Unhide files on the Time Machine backup drive

You may accidentally press the Command + Shift + .(the period key) to hide backups on the Time Machine drive. To verify that, press the shortcuts again to unhide them.

Check your network connection

If you've backed up your Mac to a network disk or a server, check if the network is unstable or broken. Check and reconnect the network to let the Time Machine backups become visible on the network disk or server again.

If you've accidentally deleted Time Machine backups or fail to use other ways to find them on the external drive, you can use a data recovery tool to help you scan and recover the backups.

Run Disk Utility First Aid to check the Time Machine backup disk

When an external hard drive is corrupted or has some errors, abnormal performance will happen like files on the external hard drive are missing. You can run Disk Utility First Aid to check and repair the external hard drive.

Update your Mac

System bugs can also lead to external hard drives behaving abnormally, like Time Machine backups not visible on external drives.

Besides, maybe the Time Machine backup drive has been used for years and you suddenly remember there are files on it, only to find no content shows up.

That's because the disk driver of the external hard drive is outdated. To update the disk driver and fix system errors, just update your Mac.
