After months of waiting, macOS Big Sur was released in November 2020. No matter how great macOS Big Sur is, you can experience performance issues as you update your Mac. The good thing is you can downgrade to the previous macOS version.

There are two ways to revert from Big Sur to Catalina. The first one involves restoring a Time Machine backup. The second, which is a bit lengthy, explains how to downgrade to Catalina using a bootable installer. Whichever way you choose, we'll provide step-by-step instructions to help you downgrade.

Open this article on your phone to make sure you do everything step-by-step.

How to downgrade from macOS Big Sur using Time Machine

If you’ve backed up your Mac with Time Machine before upgrading to Big Sur, downgrading to Catalina will be easy. Here’s how to downgrade from macOS Big Sur to Catalina using Time Machine.

1. Back up your data

First, back up everything. Your Mac probably contains your personal data and documents that you don’t want to lose. So, to keep those alive after the downgrade, you need to back up your data.

You can use Google Drive, iCloud Drive, or any other cloud you prefer. After the backup is done, you can move on to the next step.

Before you begin reverting your Mac to macOS Catalina, it’s worth trying fixing performance issues on macOS Big Sur. Maybe you won’t need to downgrade at all.

CleanMyMac X can help identify and solve performance problems on your Mac. It’s a dedicated Mac cleaner that clears old junk and runs optimization tasks. It’s notarized by Apple, which means it’s safe for your Mac. Get CleanMyMac X for free to run a quick performance scan.

2. Erase your Mac’s hard drive

The first step is plugging your Mac into power (the downgrade process may take a while, and you don’t want your Mac to power off unexpectedly).

You’ll need to erase your Mac’s drive. This will remove everything from your Mac, but you can restore your data later from a Time Machine backup.

Restart your Mac (Apple menu > Restart).
Hold Command-R when your Mac’s rebooting. The Utilities menu should appear.
Choose Disk Utility.
Click Continue and select Startup Disk (usually located at the top of the list ).
Press Erase.
Select the APFS file format.
Choose GUID Partition Map and confirm.

Wait for the process to complete. Only after every piece of data is removed, can you clean install macOS Catalina.

3. Use Time Machine to restore your backup

You can now restore all your files and data and bring your Mac back to the condition it was in before you installed macOS Big Sur.

If your Time Machine backup is stored on the external drive, plug it in your Mac.

So, to restore your Time Machine Catalina backup:

Restart your computer and hold Command-R when it reboots.
Select the Restore From Time Machine Backup option on the Utilities window.
Press Continue.
Choose your Time Machine backup disk.
Select the backup you want to restore from. Choose the most recent backup that occurred before you installed macOS Big Sur.
Then, select a destination disk, where the contents of your backup will be stored.
Click Restore and press Continue.

The process may take some time. Your Mac will restart running macOS Catalina.

How to downgrade from macOS Big Sur using a bootable installer

If you didn’t back up your Mac with the Time Machine, it’s too bad. But, you can still downgrade to the previous OS version. Just follow the instructions.

1. Back up your files and data

Backing up your data is important. It prevents you from losing all the files and data that have existed on your Mac's drive for a while. So, don’t forget to back up your Mac before you start downgrading to Catalina.

2. Create a bootable installer

A bootable installer will help you safely roll back to Catalina. Here’s how to create a bootable installer:

You can go to the App Store and search for Catalina, then download it. Quit the installer, if it tries to install the OS.
If your Mac already runs macOS Big Sur, download the macOS Catalina here.
Get an external hard drive that has at least 12 GB of available storage and plug it in your Mac.
Launch the Disk Utility app and erase your hard drive selecting Mac OS Extended format.

Now, it’s time to transfer your Catalina installer to your hard drive:

Open Terminal (Applications > Utilities).
Paste this command and press Enter:

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

The downloaded file, which is your bootable Catalina installer, should be in your Applications folder. MyVolume is the name of the hard drive; if your hard drive or flash drive has a different name, replace MyVolume with the name of your hard drive.

If prompted, enter your administrator password and press Enter again. Terminal won’t show anything when you type your password.
Follow the instructions that appear in the Terminal.
When Terminal says “done”, your hard drive should have the same name as the installer you downloaded (for example, Install macOS Catalina).

Quit Terminal and eject the hard drive.

Install macOS Catalina

Now, you can roll back from macOS Big Sur using the bootable installer.

Plug your hard drive (which is now your bootable installer) into your Mac.
Open System Preferences > Startup Disk. Choose your bootable installer as a startup disk and press Restart.

Your Mac should start up to macOS Recovery.
Make sure your Mac has an internet connection to download firmware updates (you can use the Wi-Fi menu in the menu bar).
In the Utilities window, select Install macOS.
Click Continue and follow the on-screen instructions.

Your Mac will then start installing macOS Catalina and will restart when it’s done.

Mac runs slowly after the update?

If your Mac is slow after the update, but you don’t want to perform this lengthy process and revert to the previous OS, you could try a quick solution. CleanMyMac X has a helpful Maintenance feature that could fix all possible problems on your Mac.

Open CleanMyMac X.
Go to the Maintenance module.
Press View All 9 Tasks.
Check the boxes next to the maintenance tasks you want to run.
Press Run.

Wait till CleanMyMac X runs the set of fixes to speed up your Mac.

Reverting to the previous macOS may seem like a terrifying task. But if you open this article on your phone or another device and follow the instructions, it will be much easier and faster. Don’t forget to clear your Mac before the backup – you will save a lot of free space and remove old clutter that slows down your machine.

What you should already know

You should be able to:

Understand the general software development process for object-oriented applications using an IDE (integrated development environment) such as Android Studio.
Demonstrate that you have at least 1-3 years of experience in object-oriented programming, with some of it focused on the Java programming language. (These practicals will not explain object-oriented programming or the Java language.)

A computer running Windows or Linux, or a Mac running macOS. See the Android Studio download page for up-to-date system requirements.
Internet access or an alternative way of loading the latest Android Studio and Java installations onto your computer.

How to install and use the Android Studio IDE.
How to use the development process for building Android apps.
How to create an Android project from a template.
How to add log messages to your app for debugging purposes.

Install the Android Studio development environment.
Create an emulator (virtual device) to run your app on your computer.
Create and run the Hello World app on the virtual and physical devices.
Explore the project layout.
Generate and view log messages from your app.
Explore the `AndroidManifest.xml` file.
After you successfully install Android Studio, you will create, from a template, a new project for the Hello World app. This simple app displays the string 'Hello World' on the screen of the Android virtual or physical device.
Here's what the finished app will look like:
Android Studio provides a complete integrated development environment (IDE) including an advanced code editor and a set of app templates. In addition, it contains tools for development, debugging, testing, and performance that make it faster and easier to develop apps. You can test your apps with a large range of preconfigured emulators or on your own mobile device, build production apps, and publish on the Google Play store.
Note: Android Studio is continually being improved. For the latest information on system requirements and installation instructions, see Android Studio.
Android Studio is available for computers running Windows or Linux, and for Macs running macOS. The newest OpenJDK (Java Development Kit) is bundled with Android Studio.
To get up and running with Android Studio, first check the system requirements to ensure that your system meets them. The installation is similar for all platforms. Any differences are noted below.
Navigate to the Android developers site and follow the instructions to download and install Android Studio.
Accept the default configurations for all steps, and ensure that all components are selected for installation.
After finishing the install, the Setup Wizard will download and install some additional components including the Android SDK. Be patient, this might take some time depending on your Internet speed, and some of the steps may seem redundant.
When the download completes, Android Studio will start, and you are ready to create your first project.
Troubleshooting: If you run into problems with your installation, check the Android Studio release notes, or get help from you instructors.
In this task, you will create an app that displays 'Hello World' to verify that Android studio is correctly installed, and to learn the basics of developing with Android Studio.

Open Android Studio if it is not already opened.
In the main Welcome to Android Studio window, click Start a new Android Studio project.
In the Create Android Project window, enter Hello World for the Application name.
Verify that the default Project location is where you want to store your Hello World app and other Android Studio projects, or change it to your preferred directory.
Accept the default android.example.com for Company Domain, or create a unique company domain.
If you are not planning to publish your app, you can accept the default. Be aware that changing the package name of your app later is extra work.
Leave unchecked the options to Include C++ support and Include Kotlin support, and click Next.
On the Target Android Devices screen, Phone and Tablet should be selected. Ensure that API 15: Android 4.0.3 IceCreamSandwich is set as the Minimum SDK; if it is not, use the popup menu to set it.
These are the settings used by the examples in the lessons for this course. As of this writing, these settings make your Hello World app compatible with 97% of Android devices active on the Google Play Store.
Leave unchecked the Include Instant App support and all other options. Then click Next. If your project requires additional components for your chosen target SDK, Android Studio will install them automatically.
The Add an Activity window appears. An `Activity` is a single, focused thing that the user can do. It is a crucial component of any Android app. An `Activity` typically has a layout associated with it that defines how UI elements appear on a screen. Android Studio provides `Activity` templates to help you get started. For the Hello World project, choose Empty Activity as shown below, and click Next.
The Configure Activity screen appears (which differs depending on which template you chose in the previous step). By default, the empty `Activity` provided by the template is named `MainActivity`. You can change this if you want, but this lesson uses `MainActivity`.
Make sure that the Generate Layout file option is checked. The layout name by default is `activity_main`. You can change this if you want, but this lesson uses `activity_main`.
Make sure that the Backwards Compatibility (App Compat) option is checked. This ensures that your app will be backwards-compatible with previous versions of Android.
Click Finish.
Android Studio creates a folder for your projects, and builds the project with Gradle (this may take a few moments).
Tip: See the Configure your build developer page for detailed information.
You may also see a 'Tip of the day' message with keyboard shortcuts and other useful tips. Click Close to close the message.
The Android Studio editor appears. Follow these steps:
Click the activity_main.xml tab to see the layout editor.
Click the layout editor Design tab, if not already selected, to show a graphical rendition of the layout as shown below.
Click the MainActivity.java tab to see the code editor as shown below.

If not already selected, click the Project tab in the vertical tab column on the left side of the Android Studio window. The Project pane appears.
To view the project in the standard Android project hierarchy, choose Android from the popup menu at the top of the Project pane, as shown below.
Note: This chapter and other chapters refer to the Project pane, when set to Android, as the Project > Android pane.

If the Gradle Scripts folder is not expanded, click the triangle to expand it.
This folder contains all the files needed by the build system.
Look for the build.gradle(Project: HelloWorld) file.
This is where you'll find the configuration options that are common to all of the modules that make up your project. Every Android Studio project contains a single, top-level Gradle build file. Most of the time, you won't need to make any changes to this file, but it's still useful to understand its contents.
By default, the top-level build file uses the `buildscript` block to define the Gradle repositories and dependencies that are common to all modules in the project. When your dependency is something other than a local library or file tree, Gradle looks for the files in whichever online repositories are specified in the repositories block of this file. By default, new Android Studio projects declare JCenter and Google (which includes the Google Maven repository) as the repository locations:
Look for the build.gradle(Module:app) file.
In addition to the project-level `build.gradle` file, each module has a `build.gradle` file of its own, which allows you to configure build settings for each specific module (the HelloWorld app has only one module). Configuring these build settings allows you to provide custom packaging options, such as additional build types and product flavors. You can also override settings in the `AndroidManifest.xml` file or the top-level `build.gradle` file.
This file is most often the file to edit when changing app-level configurations, such as declaring dependencies in the `dependencies` section. You can declare a library dependency using one of several different dependency configurations. Each dependency configuration provides Gradle different instructions about how to use the library. For example, the statement `implementation fileTree(dir: 'libs', include: ['*.jar'])` adds a dependency of all '.jar' files inside the `libs` directory.
The following is the build.gradle(Module:app) file for the HelloWorld app:
Click the triangle to close Gradle Scripts.

app and `res` folders.
Expand the app folder, the java folder, and the com.example.android.helloworld folder to see the MainActivity java file. Double-clicking the file opens it in the code editor.
The java folder includes Java class files in three subfolders, as shown in the figure above. The com.example.hello.helloworld (or the domain name you have specified) folder contains all the files for an app package. The other two folders are used for testing and described in another lesson. For the Hello World app, there is only one package and it contains `MainActivity.java`. The name of the first `Activity` (screen) the user sees, which also initializes app-wide resources, is customarily called MainActivity (the file extension is omitted in the Project > Android pane).
Expand the res folder and the layout folder, and double-click the activity_main.xml file to open it in the layout editor.
The res folder holds resources, such as layouts, strings, and images. An `Activity` is usually associated with a layout of UI views defined as an XML file. This file is usually named after its `Activity`.

manifests folder contains files that provide essential information about your app to the Android system, which the system must have before it can run any of the app's code.
Expand the manifests folder.
Open the AndroidManifest.xml file.
The `AndroidManifest.xml` file describes all of the components of your Android app. All components for an app, such as each `Activity`, must be declared in this XML file. In other course lessons you will modify this file to add features and feature permissions. For an introduction, see App Manifest Overview.
In this task, you will use the Android Virtual Device (AVD) manager to create a virtual device (also known as an emulator) that simulates the configuration for a particular type of Android device, and use that virtual device to run the app. Note that the Android Emulator has additional requirements beyond the basic system requirements for Android Studio.
Using the AVD Manager, you define the hardware characteristics of a device, its API level, storage, skin and other properties and save it as a virtual device. With virtual devices, you can test apps on different device configurations (such as tablets and phones) with different API levels, without having to use physical devices.

In Android Studio, select Tools > Android > AVD Manager, or click the AVD Manager icon in the toolbar. The Your Virtual Devices screen appears. If you've already created virtual devices, the screen shows them (as shown in the figure below); otherwise you see a blank list.
Click the +Create Virtual Device. The Select Hardware window appears showing a list of pre configured hardware devices. For each device, the table provides a column for its diagonal display size (Size), screen resolution in pixels (Resolution), and pixel density (Density).
Choose a device such as Nexus 5x or Pixel XL, and click Next. The System Image screen appears.
Click the Recommended tab if it is not already selected, and choose which version of the Android system to run on the virtual device (such as Oreo).
There are many more versions available than shown in the Recommended tab. Look at the x86 Images and Other Images tabs to see them.
If a Download link is visible next to a system image you want to use, it is not installed yet. Click the link to start the download, and click Finish when it's done.
After choosing a system image, click Next. The Android Virtual Device (AVD) window appears. You can also change the name of the AVD. Check your configuration and click Finish.
