• 2. Support Second Screen: Catalina allows using an iPad as a second screen from a Mac computer.
• 3. Sidecar - use your iPad as drawing tablet: Users can use Apple Pencil to draw and annotate on their iPad after connecting it to a Mac using Sidecar.

Mac Update Deleted Everything

Unfortunately, it sounds like you've experienced a catastrophic data loss due to the Catalina update. Since the update wiped your entire hard drive, it's likely that all your files, including documents, mail, and folders, were deleted. However, you can try recovering your lost files using third-party data recovery software, such as Disk Drill or Deep Data Recovery Wizard. These tools can scan your hard drive for deleted files and attempt to recover them. Be cautious, though, as some data recovery software may not work effectively or may even cause further damage to your system. If you're unable to recover your files using these tools, you may want to consider seeking professional help from a data recovery service or contacting Apple support for further assistance. I hope this helps, and I wish you the best of luck in recovering your lost files!

Mac users who lost data during a macOS update often have three main concerns: why the update deleted their files, whether the lost data can be recovered, and how they can get the new features while also retrieving their lost files.

To start Mac data recovery due to macOS update, check the causes first and learn why your data can be restored. Very few Mac users know the causes of data loss after macOS updates, but understanding them is key to successfully recovering your data.

Why did macOS update delete everything?

While upgrading to a subsequent major release of macOS, users can generally expect their user data to be preserved and untouched. Pre-installed apps and configurations will also remain intact. However, it's essential to exercise caution and responsibility when upgrading, as rare issues can still occur, potentially leading to data loss due to hardware or software problems.

• Hard drive failure or file system error
• Unfinished macOS update, macOS update failure, or OS crash
• Not enough space on the hard drive for OS update

Is lost data recoverable?

Lost files on a Mac can still be recovered because deleting a file only removes the pointer to it, not the actual file itself. The data remains on the system until it's overwritten with new information, making it possible to retrieve the deleted file.

If your files go missing after a Mac update, stop using the device immediately to prevent new data from being written to the hard drive. Then, follow the solutions below to recover your lost data after the macOS 10.15 update.

Step 1. Open up Launchpad on Mac, click "Others".

Step 2. To locate the Time Machine icon, click the Launchpad icon on your Mac's Dock, then click the "Other" button. This will open a window showing all the apps on your computer.

Solution 3. Recover Missing/Lost Files from iCloud Backup

Mac users who back up their files to iCloud may be disappointed when their files go missing or get lost after a macOS update, as the backup process may not always be seamless.

Here are the steps to recover lost Mac files from an iCloud backup:

Step 1. To access iCloud.com on your Mac, open your preferred browser and navigate to iCloud.com.

Step 2. To access the bottom of the page, scroll down on your device. On a computer, you can use the scroll bar on the right side of the page.

Step 4. Select the files you want to restore or click "Select All" to restore all of them. Then, click the Restore button to recover them.

Solution 4. Restore Files from APFS Snapshot using macOS Recovery

macOS Recovery, similar to System Restore in Windows, allows users to restore files from an APFS snapshot. This feature is available on macOS Catalina, Mojave, and High Sierra, enabling users to recover their files in case of a system failure or other issues.

To initiate the installation or update of macOS, you must first agree to the license terms, which enables snapshots to start automatically. A snapshot captures the current state of the target disk, including files and the macOS version, at the point of installation or update. It's essential to note that this feature is exclusive to APFS-formatted drives, meaning if the target drive is not formatted with APFS, no snapshot will be taken.

If you don't want to revert macOS Catalina or Mojave to the previous state, go back to solution 1 and let reliable Mac file recovery software help, which can recover your lost files without having to restore your Mac to a previous state.

If your Mac hard drive is with APFS, you can accept the result of restoring files from APFS snapshot, bringing macOS to the previous state, follow the steps below:

Step 1. To restart your Mac and boot into Recovery Mode, simply restart your computer and hold down the Command (⌘) and R keys simultaneously as it boots up. This will allow you to access the Recovery Mode, where you can perform various tasks such as reinstalling macOS, running disk utilities, or restoring from a Time Machine backup.

Release these keys when you see the Apple logo.

Step 2. Select Restore From Time Machine Backup and then click the Continue button.

Step 3. Disks connected to your Mac that contain APFS snapshots will be listed. Select the Mac startup disk and click "Continue".

Step 4. A list of snapshots will be displayed, sorted by date with the created image of the macOS version. Select the snapshot you wish to restore from, then click "Continue".

You'll see a progress bar, and your Mac will automatically restart once the recovery is complete. After the reboot, you can access and view your recovered files from the previous macOS. If you still want to update to the latest macOS, back up your data and try again.
