Full Guide: Recover Lost Data on macOS Catalina

PAGE CONTENT:

macOS Catalina is a powerful operating system that enhances productivity and offers a seamless user experience. However, like any technology, it isn't immune to issues such as data loss. Whether caused by accidental deletion, system crashes, or a failed macOS upgrade, losing important files can be a nightmare. Fortunately, recovering lost data is possible if you act swiftly and use the right methods. This article explores step-by-step solutions to recover lost data on macOS Catalina, ensuring minimal disruption to your work.

Preliminary Steps to Attempt Recovery on macOS Catalina

1. Check the Trash Bin

One of the simplest ways to recover a deleted file is by checking the Trash. When you delete a file, macOS typically moves it to the Trash instead of permanently erasing it.

1. Open the Trash from the Dock.
2. Look for the deleted file using the search bar or manual browsing.
3. Right-click the file and select Put Back to restore it to its original location.

   

💡 Tip: If you regularly empty your Trash, this option might not be helpful, and you'll need to explore other recovery methods.

2. Search for Files Using Spotlight

Sometimes, files are misplaced rather than deleted. Use Spotlight to search for your missing data:

1. Press Command + Space to open Spotlight.
2. Type the file name or a keyword related to it.
3. Check the search results and double-click the file to access it.

Spotlight is a fast and efficient way to locate files, especially when the issue is misplacement rather than deletion.

3. Review Time Machine Backups

Time Machine is macOS's built-in backup solution. If you've set it up, restoring files becomes a breeze.

1. Connect your Time Machine backup drive.
2. Open the folder where the file was stored.
3. Launch Time Machine from the menu bar.
4. Use the timeline on the right to navigate to a date before the file was lost.
5. Select the file and click Restore.

Time Machine backups ensure that you can recover files lost to accidental deletions or system crashes.

Use Built-In macOS Tools for Disk Repair & Recovery

1. Disk Utility

Disk Utility is a versatile tool for managing and troubleshooting disks. If data loss is due to disk corruption, Disk Utility can help repair the issue.

1. Open Disk Utility from Applications > Utilities.
2. Select the drive or partition where the data was stored.
3. Click First Aid and run a repair.

If the drive has minor errors, this method can help restore its functionality, potentially making the lost data accessible again.

2. Terminal Commands

For tech-savvy users, macOS Terminal offers commands to attempt data recovery. Use these commands cautiously to avoid further data loss.

1. Open Terminal from Applications > Utilities.
2. Run the following command to list all drives:

   diskutil list

3. Identify your drive and mount it (if it's unmounted):

   diskutil mount /dev/diskX

   Replace diskX with the appropriate identifier.

4. Search for lost files using ls commands and copy them to a safe location.

Terminal commands are advanced and best used if you're confident in working with macOS's command-line interface.

   • Keep third-party applications up to date to avoid compatibility issues that might lead to data corruption.
5. Enable FileVault:
   • Encrypt your disk using FileVault to protect data from unauthorized access. While this doesn't prevent loss, it ensures privacy in the event of a device theft.
6. Set Up File Syncing Services:
   • Use tools like SyncThing or Resilio Sync to keep files synchronized across multiple devices. This minimizes the impact of losing files on one system.
