Lost files after upgrading to macOS Catalina/Big Sur, help!

Hi all, after recently trying to update to macOS from Catalina to Big Sur, my entire hard drive has been wiped. Nothing on my desktop, documents, mail, folders, etc. and the files I used most often all disappeared. The applications are there but that's it. I search for Trash, but no luck. Very annoying. Is there any way I can restore the lost files?

As macOS Big Sur is coming with many attractive features, you probably already have upgraded to the new operating system. However, like the problems found in macOS Catalina update, macOS Big Sur could also run into troubles in updating. The worst part is, just like what happened above, some Mac users reported that after macOS upgrade, files on their MacBook or iMac are gone. If you have encountered a similar situation, try the following solutions to recover lost files after macOS Catalina or Big Sur update.

How to recover missing files after macOS Catalina/Big Sur update?

Before upgrading to macOS 10.15 or macOS 11, you should make a backup of your Mac. This is always a good idea in case the changes bring something unexpected like data loss. But if you forgot to back up important files, no worries! You can follow the steps below:

Solution 1:Check another folder

This had happened in macOS Catalina update last year. Apple Developer indicated in macOS 10.15 release notes that Macintosh HD contains files on the root of the volume, so files/folders stored at the root level of the volume will be relocated to /Library/SystemMigration/History/Migration-UUID/QuarantineRoot/ when the Mac upgrades to macOS Catalina. So, you can go to this folder to check if you can find those relocated items after macOS Big Sur update as well.

Solution 2:Restore lost data from Time Machine Backup

When it comes to restoring some of those files or your entire Mac, Time Machine app makes it easy. But this method works well only if you have Time Machine backups. You can try the following steps to see if you can restore lost data from Time Machine Backup.

1. Restore specific files/folders from your Time Machine backup

If you only want to restore specific files and folders from a Time Machine Backup, you can restore them by proceeding with this tutorial.

Step 1: Open up Launchpad on Mac and click Other.

Step 2: Find the Time Machine icon and click it to enter.

Tips: You can also open Time Machine by clicking the Time Machine icon in the menu bar and then choose Enter Time Machine. If the Time Machine icon isn't in the menu bar, go to Apple menu and choose System Preferences, click Time Machine and then check the box next to Show Time Machine in menu bar.

Step 3: Use the arrows at the bottom and timeline on the left to browse the backups.

Step 4: Select the files or folders that you want to recover and click Store.

2. Restore your Mac from a Time Machine backup

If your Mac crashes and you lose it all after upgrading to macOS Catalina, you can use Time Machine backups to restore your Mac.

Step 1: Restart your Mac and while the startup disc is walking up, hold down the Command + R keys simultaneously. Your Mac will boot into macOS Recovery mode and you will see the macOS Utilities window. (If your Mac won't boot into macOS Recovery mode, please try again).

Step 2: Select Restore from Time Machine Backup; under the macOS Utilities and click Continue.

Step 3: Read the info on the Restore Your System page and click Continue.

Step 4: Select the disk that contains the Time Machine backup and click Continue.

Step 5: You will see a list of all versions of backups in the form of APFS snapshot. Choose the most recent backup of your hard disk and click Continue. Your Mac will restore the Mac from the selected version of backup and then restart once it is finished.

Solution 3:Recover lost files from the iCloud backup

If the Time Machine Restore failed or greyed out, you can rely on iCloud Drive. As the most common cloud storage service on iOS and Mac computers, iCloud drives are used to store and sync files between various devices. People store more and more items into iCloud storage in order to reduce the local storage space of Macs. But don't ignore the hidden restore feature on iCloud. With this feature, you can recover deleted/lost files, recover photos, videos, contacts, bookmarks, calendars, and reminders from iCloud backup.

Step 1: Go to iCloud.com in any web browser and log in.

Step 2: Click on the Setting icon and then scroll down to the bottom of the page that appears.

Step 3: At the bottom left, click on Restore Files under Advanced.

Tips: If you want to restore contacts, bookmarks, calendars and reminders from iCloud, click the corresponding option under Advanced.

Step 4: Check off the boxes to the left of the files you want to restore or click Select All if you really need to restore everything. Click the Restore button to recover them to iCloud Drive.

Potential problems with macOS Catalina/Big Sur upgrade

Whether it is a beta version or a public release, the operating system upgrades or updates were designed to go smoothly but things always didn't go as what you have expected. It's possible that you might get into more troubles than the previous macOS has as a whole. Here are some potential problems after macOS upgrades.

Case 1: macOS Catalina/Big Sur won't download

The most common problem is that users fail to download the upgrades of macOS Catalina or Big Sur. This is because a lot of people are trying to download the new macOS 11 Big Sur at the same time. Meanwhile, downloading may also fail if you don't have a reliable internet connection or enough storage space available on your Mac. If you have tried several times but macOS updates still won't download, here is what to do exactly to fix this issue:

Fix 1: Clean App store and download cache

Go to Finder and press ⌘ + Shift + G. Locate ~/Library/Caches/com.apple.appstore and empty this folder. Then reboot your Mac and try to download macOS Catalina upgrades again.

Fix 2: Check the internet

To check the internet, go to Apple menu and then click on System Preferences. Next select Next from the Control Panel. You can try to switch a Wi-Fi connection to an Ethernet cable in order to ensure your internet connection is as stable as possible.

Fix 3: Check the RAM (memory) and available storage

To check whether your Mac has enough space to download the new macOS Big Sur, you need to click on the Apple menu on the top left of your screen and then select 'About This Mac'. Make sure you have less than 4 GB of memory. Then click on the Storage tab on the same window. You will see how much storage has been used and how much free space is available (make sure you have at least 16 GB of free disk space). If your computer doesn't have enough space, you can add more memory or free up as much as disk space as possible.

Case 2: macOS Big Sur won't install

The macOS Big Sur installation stops at 99% loading bar and won't move forward? This can sometimes point to a compatibility issue. From the preview of macOS 11 Big Sur, you can ensure that your Mac is actually compatible with Catalina

Fix: Check if your Mac can run macOS Big Sur

Firstly, you should check your Mac model and make sure you have a Mac that can run macOS Big Sur. You will see your model specifications from the a list of all the Macs that can currently run macOS 11:

Moreover, the new version cannot be installed onto an encrypted volume unless it's already in the APFS format. Last but not least, if your Mac has macOS 10.10 or earlier installed, you must first upgrade to macOS 10.14 Mojave or High Sierra before upgrading to macOS 11. If unfortunately, your Mac computer doesn't support macOS Big Sur, you should not upgrade or you can downgrade to the lower version.

Case 3: Apps freeze, crash or quit unexpectedly after macOS upgrade

App crashing after a macOS update is related to app incompatibility issues after a macOS update. This issue can mostly occur when the developer of the app hasn't released app updates compatible with the new OS requirements, or when the user hasn't installed the released app updates.

Fix 1: Force quit and restart the app

You can quickly fix a frozen and unresponsive app by forcing it to quit. Click on the Apple Menu. From the drop-down window, select the Force Quit option, choose the name of the App and then click Force Quit. After that, simply restart the app and see if it runs normally.

Fix 2: Check for App updates

If the app is downloaded from the App Store, you need to open the App Store, and then click Updates and then check the updates for the faulty app. If the app was downloaded from a third-party vendor, you should visit the vendor's website to check if there are any updates available for the app.

Fix 3: Uninstall and reinstall the crashing app

The last solution is to completely uninstall an application. This operation is more than just dragging and dropping the app in the Trash. You have to delete all of its preference files.

First of all, you need to go to Finder > Applications and locate the crashing app and drag it to Trash. Afterward, you should get rid of all of its linked files and folders. Open Finder click Go in the menu bar, hold down on the Alt/option key to bring up the Library option and then click on it. Search for the name of the application and the name of the company that created it.

Make sure you have deleted all of them. After completely uninstall the app, download and install the update again.

Case 4: Mac runs slow after macOS update

It's possible that you make the macOS update, but the system runs slow. The first reason could be that your Mac has too many programs that automatically run when your machine boots. It is also caused by the almost full startup disk on your Mac, leading to the slow performance issues. Beyond that, if you are using a mechanical hard drive or fusion drives, chances are your Mac will take much longer to start up.

Fix 1: Disable unnecessary login items

Click on the Apple menu on the top-left corner and go to System Preferences >Users & Groups. Click Login Items on the top of the window. Select the apps you don't want to open automatically and hit - option.

Fix 2: Free up the startup disk space

If you check the storage of your startup disk and find it is almost full, you need to make room for getting macOS Catalina running efficiently.

Fix 3: Replace your old hard drive with a new SSD

If your Mac has a spinning hard drive or fusion drive, the only fix is to swap out your old hard drive with a new SSD.

Case 5: Mac computer won't boot after macOS Catalina/Big Sur update

If your MacBooks and other Macs won't turn on after macOS Catalina/Big Sur update, the problem might be caused by a lack of power, some issues with Power Management System, corrupted files system of the boot drive, etc.

With the release of OS X Mountain Lion, Apple changed the way they handle software updates on the Mac. Instead of going through a dedicated Software Update pane within the Finder, software updates are now managed from within the Mac App Store. Sometimes, however, you have an app that you don’t want to update, and it can be frustrated to see the update pop up every time you want to update your apps.

Fortunately, Apple provides a simple way to hide an update. Hiding an update means you’ll never be prompted to install it until the next time a new update is released for that app. Here’s how it’s done.
