MacOS 12 Monterey is Apple’s next macOS after Big Sur. To have the best experience with Monterey, you’ll need to perform a “clean install” or, simply put, install it onto a wiped drive. This way, you’ll start from a clean slate and leave behind tons of old files.

Recently, we talked about how to install the beta version of macOS Monterey. If you did this but realized that the beta version is not suitable for you, it remains to roll back to the stable version of macOS Big Sur. Below we will tell you how to do this.

How to roll back from macOS 12 beta to macOS Big Sur

To begin with, it is worth noting a couple of nuances. If you backed up your system before installing the beta, you could restore your data from a copy of Time Machine.

To roll back, you need to format the disk on which the beta version is installed. If you installed macOS 12 beta on a disk partition, you could simply delete it, and your Mac will boot macOS Big Sur.

If you installed macOS 12 beta on your primary drive, follow the instructions below.

It is better to prepare the macOS Big Sur installer on a flash drive in advance. Once again, we note that this instruction is relevant for those who made a “clean installation” of macOS 12 beta.

1) In the menu bar, click the Applelogo and select Restart.

2) Press the Command+ R keys until the Utility menu appears.

3) Select Secure Boot Utility, enter your password and enable the Allow download from external media option.

Restart your computer again and repeat Step 2 to open the utility menu.

1) Select Disk Utility, click Continue, and select your startup disk (most likely Macintosh HD).

2) Click Erase at the top of the page and select your format. Enter a new name for the disc or leave the Macintosh HD. On new Macs APFS format, and old ones – HFS+(journaled).

3) Click the Erase button again and wait for the process to complete.

Reinstall macOS Big Sur

For a clean installation of macOS Big Sur, you need a flash drive with an installer, which you should have created in advance.

1) Connect the flash drive to your computer and select the Apple USB logo from the menu bar. Make sure you have an Internet connection.

2) Click Turn off.


3) If you have an Apple Silicon Mac, hold down the power button until the options window appears. On an Intel Mac, press the Option key immediately after turning on the computer.

4) In the startup menu, select the flash drive.

5) Click Continue.

The installation of macOS Big Sur will begin. Follow the instructions.

Restore from a copy of Time Machine

1) Connect a media with a copy of Time Machine to your computer and make sure you have an Internet connection.

2) In the menu bar, select the Applelogo and click Restart.

3) Press the Command+ R keys until the Utility menu appears.

4) Select Recover from TimeMachineBackup and click “Continue.”

5) Click Continue again, and then select the media with the copy. Select the copy itself and click Continue.

Wait for the process to complete, after which all your settings and data should be returned.

As you can see, making a rollback from macOS 12 Monterey to macOS Big Sur is not so easy. We do not recommend installing beta versions of the system on your main devices. We hope you succeeded!

The current version of the Mac operating system, macOS 11 Big Sur, was officially released last fall. But Apple often updates the OS and tries them out in betas before they are officially released. You can join Apple’s Public Beta program to try these OS updates before they are released to the general public.

Interested? Here’s what you need to know about the Public Beta.

Sign up for the program and install the macOS Big Sur Public Beta

Before you can install the new operating system, you must be enrolled in the Public Beta program. You can do this through Apple’s Public Beta program website. In the Get Started section of the website, click on the “enroll your Mac” link.

This should take you to the “Enroll you devices” webpage. Follow the instructions. In step 2, you will download the “macOS Public Beta Access Utility” which will enroll your Mac into the program. Then the utility will launch Software Update to download and install the Big Sur beta.

What is the macOS Big Sur Public Beta?

The current version of the Mac operating system is macOS 10.15 Catalina. The next version is macOS 11 Big Sur. Apple makes a public beta version of Big Sur available for people to try out, test against their favorite software, and report bugs to the company.

Since this is beta software, there’s a good chance it could cause problems on your Mac. You may encounter frequent freezes and crashes, or your apps may not work. Don’t count on it being stable enough to use all the time.

You should not install the beta on a production Mac or any other Mac you depend on and need to keep running. If you’re worried that a beta flaw will prevent you from using your Mac, don’t install it. Install it on a Mac that you consider a secondary computer.

If you do decide to try the beta, you can provide Apple with valuable feedback and get a look at the new features.

What should you do before installing it?

Back up your Mac. You can use Time Machine or whatever backup setup you already have. You need a backup you can revert to in case you need to stop using the beta and need to restore your system.
