Retrieving Time Machine backups from a different computer

How do I retrieve files from a Time Machine backup generated from a different computer and are located on an external drive? The files were saved using an older Mac OS. Currently running Golden Gate. Thanks so much!

You can retrieve files from an older Time Machine backup created on a different Mac while running macOS 27 Golden Gate using two approaches, depending on whether you want a few specific files or a full import.


Use "Browse Other Backup Disks" (for specific files)

If you prefer to browse through the file snapshots using the graphical Time Machine interface, you can force the OS to look at an inherited drive.

  • Plug in your external drive.
  • Click the Time Machine icon in your menu bar (if it's not there, toggle it on in System Settings > Menu Bar).
  • Hold down the Option (⌥) key on your keyboard.
  • The menu option "Enter Time Machine" will change to "Browse Other Time Machine Disks..." or "Browse Other Backup Disks...". Click it.
  • Select the old backup disk from the list and click Use Selected Disk.
  • This will take you into the classic Time Machine timeline interface. Navigate to the files you want, right-click (Control-click) them, and choose Restore [item] to... to save them onto your current Mac.


Use Migration Assistant (for moving a whole user account)

If you want to migrate everything—such as your entire old user profile, all applications, and settings—into your new system, you should use Apple's built-in migration tool.

  • Connect the external drive.
  • Open Migration Assistant (located in Applications > Utilities folder, or find it via Spotlight).
  • Click Continue and enter your Mac's administrator password.
  • When asked how you want to transfer your information, select From a Mac, Time Machine backup, or startup disk.
  • Select your external Time Machine drive and select the specific backup user you wish to pull data from.
  • Check the boxes next to the data categories you want to bring over (e.g., Users, Applications) and click Continue to start the transfer, a new user will be created for the data.

Choose Utilities from the Finder's Go menu and use the Migration Assistant. It'll put the data into a new user account.
