The Mac OS sierra stands thirteenth in the Mac OS series. Mac OS sierra launched in mid-2016 made a drastic entry into the market after the OS X. Mac OS sierra made a revolutionary shift from the recent trends in the Mac OS history. The Mac OS series had some issues when it came to the graphical user interface which was frowned upon by many. Mac OS X Snow Leopard (version 10.6) is the seventh major release of macOS, Apple's desktop and server operating system for Macintosh computers. Snow Leopard was publicly unveiled on June 8, 2009 at Apple’s Worldwide Developers Conference.

Get Setapp, a toolkit with fixes for all Mac problems

Recently switched to macOS 11 Big Sur? This means you’re in for some huge enhancements and a completely redesigned look. It's fair to say Big Sur is not a perfect fit for everyone, though. Can you go back to previous macOS if that's the case? Sure. In this article, we describe how to downgrade from macOS 11 and continue using your previous macOS without any data loss.

Before you make a decision to uninstall Big Sur, check out some common macOS 11 problems and fixes. Maybe, the problem that is hampering your flow is on the list — and you can easily solve it. Also, if your Mac runs macOS Big Sur beta, you should know the public version available starting November 12 fixes most of the problems.

If you go like 'All right, thanks, just tell me how do I uninstall Big Sur from my Mac' — fair enough. The good news is it's easy to roll back macOS update. Follow the guide below.

How to downgrade from Big Sur step by step

Just to clarify the process a little bit, a downgrade from Big Sur covers five important steps — from backing up all the files you've acquired since upgrading, to restoring those on macOS Catalina. There are a few tools you'll need to use to downgrade safely: Primarily, a backup utility (Apple's native Time Machine or a more advanced third-party app like Get Backup Pro) and CleanMyMac X for keeping things tidy. Now when you're all set, let's get into it.

Best backup app for Mac

Before you roll back to the old macOS, create a secure backup of all your data with Get Backup Pro. So that there’s nothing to lose.

1. Backup your data (pretty please)

Even if you've just recently upgraded and haven’t managed to accumulate lots of data on macOS Big Sur, don’t skip this step. Downgrading means you erase everything from your hard drive. So whatever you’ve been working on since installing macOS 11 will be gone. Make sure you avoid the trouble and create a quick backup. You can do this with Time Machine, but we recommend Get Backup Pro for creating a bootable backup. This will give you an exact copy of your drive, with all saved settings — so that you can pick up where you left off.

Here’s how to back up data before you uninstall Big Sur:

  1. Open Get Backup Pro from Setapp

  2. Hit the plus button at the bottom to create a new backup

  3. Name your backup project

  4. Pick a backup destination and customize settings if necessary

  5. Choose files, folders, and apps data you want to add to the backup

  6. Hit Start.

It’s a good idea to use CleanMyMac X for a system cleanup before you create a backup. This way, you’ll avoid backing up unneeded files and duplicates, and therefore run a smooth and quick backup process. Plus, the app is generally a good tool to keep at your fingertips to remove any clutter. Believe me, your Mac has a lot of it. Here’s how CleanMyMac X works:

  1. Open the app and hit Scan

  2. Wait for CleanMyMac X to finish the scanning process

  3. Hit Run if you want to remove all the junk, or Review if you want to select the files that should be deleted manually

  4. That’s it! You’re all set for a clean backup.

2. Install macOS Catalina on a bootable drive

It might seem a bit counterintuitive, but you have to install macOS Catalina on an external drive before you erase Big Sur. This requires some Terminal work, which we’ll guide you through in a minute. Before that, make sure your Mac can boot from external media.

Allow booting from external media on new Macs

If you own a MacBook Air, MacBook Pro, or Mac mini with the T2 security chip (2018 models and newer), you might experience problems with booting files. To avoid this, you should allow booting from external media before you run downgrade to Catalina:

  1. Restart your computer and boot in Recovery Mode (hold down Command + R once the Apple logo appears)

  2. Access Utilities > Startup Security Utility

  3. Enter your firmware password (note that this is the password you used to enable Startup Security Utility and it’s different from your admin and Apple ID credentials)

  4. In External Boot, check the box next to “Allow booting from external media.”

Once you’re all set, it’s time to get Catalina back. First, download macOS Catalina from the Mac App Store, the usual way. While installers of the latest macOS versions are available only before the official release of the new one, you should do this as early as possible.

Then, install macOS Catalina on an external drive. Start with formatting the drive (you can skip this step if you have a formatted drive):

  1. Get an external drive with minimum 12GB of free space

  2. Connect it to your Mac via USB

  3. Open Finder > Applications

  4. Navigate to Utilities > Disk Utility

  5. Click Erase next to your drive (make sure you name it if you have more than one)

  6. Select APFS or macOS Extended format > Erase.

Install macOS Catalina on a formatted drive:

  1. Open Finder > Applications

  2. Launch Terminal from Utilities

  3. Type the following command

sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia--volume /Volumes/MyVolume

Note that “MyVolume” in the command above is the name of your drive, so you should change it accordingly.

  1. Click Enter/Return

  2. Confirm your action by entering the admin password > Y

  3. Click Return

  4. Once Terminal says “Done,” you can quit it and eject the hard drive.

3. Remove macOS 11 from hard drive

Now is the time for goodbye. Here’s how to downgrade from Big Sur to Catalina by removing macOS 11 from your hard drive:

  1. Click on the Apple logo and select Restart from the menu

  2. Hold down Command + R to reboot in Recovery mode

  3. Open Disk Utility > Continue

  4. Select your Startup Disk > Erase

  5. Select APFS or macOS Extended format and confirm your action.

4. Reinstall macOS Catalina on your Mac

Next thing, run a downgrade to Catalina by reinstalling it on Mac:

  1. Make sure your Mac is connected to the internet

  2. Connect your bootable external drive

  3. Click on the Apple logo and select Restart from the menu

  4. While your Mac restarts, hold down Option

  5. Once the list of startup disk options appears, select the bootable drive with macOS Catalina installer

  6. Hit Continue, agree to the licensing terms, and wait for macOS Catalina to reinstall.

5. Restore data from backup

The last step is to bring back all the data you’ve compiled since upgrading to Big Sur. Again, a backup is essential since it will help restore both your files and saved settings. You can restore everything with the same tool you’ve used previously to create a backup.

Here’s how to restore a Time Machine backup:

  1. With your Mac connected to the internet, restart the system

  2. Hold down Command + R to enter Recovery

  3. Access Utilities > Restore from Time Machine Backup > Continue

  4. Select the backup source > Continue

  5. Select your backup > Continue

  6. After Time Machine restores data from the backup, your Mac will reboot.

If you used Get Backup Pro for your backup, restoring data is even easier. All you have to do is launch the app, select your backup from the list, and hit Restore. Select a custom location for your files and once again click on the Restore button. That’s it. All your data and settings will be back on macOS Catalina in a minute.

That’s about it. Whenever you’re wondering how to go back to previous macOS, you can use the guide described above. All the instructions are pretty universal, except you should adjust the Terminal command when installing old macOS on a bootable drive.

In case your Mac is slowing down or else behaving strangely after the downgrade, we recommend to get iStat Menus for advanced system performance monitoring. This app will help you understand the source of the problem — whether it’s login items, network problems, or disk activity — and fix them accordingly.
