“Hello, world, Apple’s new macOS version is released lately. And so I’ve upgraded my Mac to the latest macOS Catalina 10.15. But things didn’t go well for me. After the upgrade, I found that several of my files were deleted in the process. Please help. I’ve no clue how to recover data after Catalina upgrade.”

Before upgrading to macOS Catalina 10.15, you must back up the data by using Time Machine backup drive. Time Machine ensures you won’t lose any data due to drive erasure that is performed when macOS is installed on your MacBook, iMac, or Mac mini. 

Recover Deleted Files on macOS Catalina 10.15

1. By using Time Machine

If you have backed up your Mac by using Time Machine before macOS Catalina upgrade, then follow the next steps to restore your Mac from the backup.

Step 1. Ensure you connect the Time Machine backup drive to your Mac.

Step 2. Restart your Mac and press and hold Command + R keys together. Release them when the Apple logo appears. Now, your Mac enters macOS Recovery Mode.

Step 3. From the macOS Utilities window, select “Restore from Time Machine Backup” then click Continue.

Step 4. Select your Time Machine backup drive—the restore source, then click Continue.

Step 5. Select the latest backup then click Continue.

Step 6. Then again, select a destination drive (Macintosh HD—the startup disk), then click Restore.

Step 7. Once the restoration process is over, restart your Mac.

Now, you’ll find all your data back to your Mac as it was before.

2. By using macOS Catalina Data Recovery Software

In case you didn’t back up your Mac before upgrading to macOS Catalina, don’t worry. Immediately stop using your Mac until you recover all your deleted files.

Step 5. For startup disk scanning, Catalina’s system integrity protection or SIP would need to be temporarily disabled. For that, follow the steps on how to enable/disable SIP in macOS Catalina and then proceed to the following Step 6.

Step 6. During the scanning process, you’ll find runtime preview of files. Click OK when the scanning process is over. The software will list all the scanned items.

There you go; you’ve recovered your files deleted after upgrading to macOS Catalina 10.15. Now you can transfer those files back to your Mac. Nonetheless, don’t forget to back up your data by using Time Machine.

Also, if you care for your important data, then maintain at least three copies of it. One copy is present on the Mac. And the other two copies on two different backup media types (hard drives, solid-state drives). Further, keep one backup copy in an offsite location—say cloud storage space—to deal with a natural disaster.
