Time Machine keeps snapshots of your Mac so you can restore one file, an older folder version, selected user data, or an entire Mac after erase or replacement.
This guide applies to Macs with an existing Time Machine backup stored on an external drive, network drive, NAS, or Time Capsule.
Does This Affect You?
Use Time Machine restore when you deleted a file, need an older version, are setting up a replacement Mac, or need to rebuild after a crash or fresh macOS install.
Restore Individual Files or Folders
- Connect the Time Machine backup drive or make sure the network backup is available.
- Open Finder to the folder where the missing file belonged.
- Open Time Machine from the menu bar or Spotlight.
- Use the timeline or arrows to move back to a date when the file existed.
- Select the file or folder and click Restore.
- If offered, Browse All Versions can restore one supported file from within its app or Finder context.
Restore a Whole Mac During Setup
This is the path for a replacement Mac, freshly erased Mac, or reinstall where you want the old Mac’s data brought back during setup.
- Start the Mac and reach Setup Assistant.
- On the Apps & Data or Migration Assistant screen, choose to restore from a Time Machine backup.
- Connect or select the backup disk.
- Choose the backup date.
- Select the user accounts and data to restore.
- Let the restore finish. Large backups can take from minutes to several hours.
Transfer Data Without Erasing
- Open Migration Assistant from Applications > Utilities.
- Close other apps when prompted.
- Choose to transfer from a Mac, Time Machine backup, or startup disk.
- Select the backup and date.
- Choose accounts, apps, settings, or files to bring over.
- Continue and let Migration Assistant add the selected data alongside what already exists.
Time Machine Restore Notes
Snapshot Schedule
Time Machine keeps hourly backups for the last day, daily backups for the last month, and weekly backups as space allows.
Network Backups Work Too
NAS and Time Capsule backups can restore the same way if the Mac can see the backup volume on the network.
Check a Problem Backup Drive
If the backup does not appear, connect it to another Mac and confirm it mounts in Finder. A damaged sparsebundle or improperly disconnected drive can prevent restore.
Apple Silicon Recovery Path
On Apple Silicon, hold the power button for startup options, choose Options, then use Recovery utilities to restore from Time Machine when needed.
