Did you delete an important file from your Mac by mistake? Or did your startup disk suddenly fail? Luckily, if you’ve been regularly backing up your Mac, you’ll be able to easily restore files from a Time Machine backup whenever needed. So, whether you want to recover a particular document, restore your Mac to an earlier version, or migrate data from the Time Machine backup to a different Mac, it’s all possible.

In this guide, we’ll give you step-by-step instructions for each of the recovery options and show you how to restore lost data even if you don’t have a Time Machine backup of your Mac.

What are the main Time Machine recovery options?

All Macs come with a built-in tool called Time Machine. It is a backup software that helps to recover accidentally deleted or corrupted files.

Through Time Machine, you can create a copy of all the files and data stored on your Mac and export them to an external drive. Then, whenever needed, you can restore any piece of information from that backup.

With Time Machine backups, you have three main options:

  • 📁 To recover a specific file: when you mistakenly deleted an important file and wish to restore only that one.
  • 💻 To restore your Mac to the state it was during a particular backup: when you reinstall macOS on your device and want to return everything as it was before.
  • 💻➡️💻To restore Time Machine backup to a new Mac: when you wish to import all of the data from the Time Machine backup to your new Mac.

3 Proven Ways of Restoring from a Time Machine

Don’t know how to restore files from a Time Machine backup properly? It’s alright; we’ve all been there. If you do everything right, you’ll be able to recover the needed data in no time.

Method #1: Restore Individual Files From Time Machine

In most cases, people resort to their Time Machine backups to recover a single file or to revert it to the same state as it was a few days or weeks ago. To do this, all that you’ll need is your Mac and the external drive containing the Time Machine backup.

Here’s how to restore individual files from Time Machine backup:

  1. Open the needed folder or file. Head to the folder where the deleted file was previously located, or open the document that you wish to revert.
  2. Launch Time Machine. You can do this either from the Launchpad or by clicking the Time Machine icon on the menu bar and then clicking Enter Time to enter time machine mac
  3. Choose the right Time Machine backup. Use the arrows or the timeline on the right side of the screen to navigate through all of the previous backups.
  4. Click on the file that you want to restore. To preview it, press Space on your keyboard. If it is the right one, then click the Restore button to confirm and recover the chosen file.

You’re all set. After the recovery is finished, the lost file should be automatically placed back into its original folder.

Note: This method works only when restoring individual files from a Time Machine backup. So, if you want to recover all of the data from the backup, check out the next method.

Method #2: Restore Entire Mac From Time Machine

If there is a problem with your startup disk and you can no longer use your Mac properly, your best option is to restore the entire macOS from a Time Machine backup to the version when your Mac had no issues.

To do this, you must have a ready Time Machine backup of your Mac on an external drive. So, to restore all of the data from a Time Machine backup, you should do the following:

  1. Connect the external drive with the Time Machine backup to your Mac. Also, make sure that it is turned on and working.
  2. Boot into macOS Recovery. To do this, head to the Apple menu and click Restart. As soon as you click it, press and hold Command + R. Hold these two keys until you see the startup screen and then follow the instructions. However, the process of running an M1 Apple Silicon Mac in the macOS Recovery mode is different: you should head to Apple menu and click Shut Down, power it back on by holding the power button until the Loading startup options screen appears, then click Options, and Continue.
  3. Click Restore From Time Machine. Use the macOS Utilities window to restore your entire Mac from a Time Machine backup.macos recovery mode options
  4. Select your external drive containing the Time Machine backup.
  5. Select the needed backup version. Check the data, click the right Time Machine backup, and then click Continue to confirm.
  6. Select a destination. Click your Mac’s hard disk to choose it as the destination. Then click Restore to start the transferring process.

Note: After you complete this process, all of the new files created after the Time Machine backup you are restoring from will disappear. So if there’s anything valuable to you in those files, it is best to copy them to an external drive before starting the recovery.

If there’s nothing wrong with your Mac and you do not need to reinstall its operating system, you can use Migration Assistant to restore the Time Machine backup. Here’s what you should do:

  1. Open the Migration Assistant. To do this, head to Finder > Applications > Migration Assistant.
  2. Transfer from a Time Machine backup. Choose to transfer your information From a Mac, Time Machine backup, or a startup disk. To confirm, click to use migration assistant to recover from time machine backup
  3. Choose the right Time Machine backup. Click Continue to move forward.
  4. Select all of the data. Place a checkmark near every information type to transfer everything from the backup to your Mac. Click Continue to start the recovery process.

Note: Don’t worry if seems like the recovery process is taking forever. Depending on how large the Time Machine backup was, it can take you from a few minutes to several hours to finish the transfer.

If you have a new MacBook that you wish to set up entirely as your old one, you can use your Time Machine backup for this job. This way, all of your user accounts, files, apps, and settings will get automatically imported into your new device.

During your new Mac’s setup process, a Transfer Information window should appear. Here’s what you should do to restore a Time Machine backup to a new Mac when you spot that window:

  1. Connect your external drive containing your Mac’s backup. Make sure that it is turned on and working.

Bonus Solution: How to Recover Data on macOS Without Time Machine Backup

But what to do if you haven’t backed up your Mac with Time Machine and need to recover an important file that you’ve mistakenly deleted? Even though Time Machine is a great tool when it comes to restoring data from a backup, it has a major downside—if you haven’t backed up your Mac before losing that file, you can’t use this tool to restore it.

If the needed file is not located in your Time Machine backup and you’ve already emptied your Trash bin, the only option that you have left is to use data recovery software.

Luckily, there are various third-party data recovery tools on the market that can help you easily recover your missing file. We’ve tested a few of the most sought-after options and can say for sure that there is a data recovery tool suitable for every Mac user.

So, when testing this application, our team decided to see how it works when recovering three types of files: a TXT file, JPG image, and MOV video clip. And the truth is, we were pretty impressed with the results since Disk Drill successfully recovered each of them. In addition to internal disks, Disk Drill also recovers data from external media, such as SD cards or external hard drives.

If you want to give Disk Drill a try, here’s what you should do:

  1. Download and install the app. Head to to automatically start the download and follow the on-screen instructions to install Disk Drill.

Yes. If you’ve made a complete Time Machine backup of your Mac, you can restore your device to exactly the same state as it was during that backup. All of the apps, files, and every other piece of information that was located on your Mac during the last backup will be restored.
There is no definite answer: the exact amount of time depends on how much data is backed up and on the speed of your connection to the external drive. So in some cases, it will take an hour to restore data from a Time Machine backup, while in other cases, it can even take up to ten hours.

No. There is no need to buy a new external drive to complete a Time Machine backup. If there is enough space left on your external hard drive for a backup, there’s nothing stopping you from using it. However, make sure that the disk is formatted correctly. Otherwise, you’ll be prompted to erase the data stored there and reformat it.

Note that if you’re using an internal drive, it should be partitioned into two volumes before the backup. And alternatively, if you wish, you can create a network backup.

Simply connect the hard drive to your Mac and head to the Apple menu > System Preferences > Time Machine, and select that external hard drive as the backup disk. As soon as you do this, Time Machine will automatically start your first full backup.
Unfortunately, no. But you can use a third-party data-recovery app to restore individual files if they haven’t been already overwritten. You can also use such apps to create a macOS backup and then use it to restore your entire Mac.
Yes. You can selectively recover individual files from a Time Machine backup to a new Mac. You’ll need to use Migration Assistant to restore specific files from a Time Machine backup.


Time Machine is an excellent tool for creating backups of your Mac’s data. If you make them regularly, then with the methods described above, you should be able to restore any valuable information stored on the external drive with the Time Machine backup.

However, there are cases when Time Machine backups don’t help. If you find yourself in such a situation, then using data recovery software might be your only chance left in getting your data back.
