macOS Big Sur 11.2 is the latest macOS update, and it’s still under development, so it’s not ready to be released as an official stable version of macOS. However, users could still try out the beta version of macOS Big Sur 11.2.

In the following lines, we will show you how you can download and install macOS Big Sur on your computer if you are interested in trying it out before it gets officially released as the current latest version of the operating system. However, before we get to the guide, we must mention a couple of things about macOS Big Sur 11.2 and software beta versions in general.

Since 11.2 is still in its beta version meaning that it is currently undergoing changes and development, this means that this version of macOS is likely to be unstable and contain different bugs and issues that will need to be resolved before it gets officially released. Even though users could download it and try it out, this is not recommended unless you have a specific reason to do so. In most cases, the people who install beta versions of different software are either beta testers, developers, or early adopters who are excited about the new features that the new software version brings.

In the case of macOS Big Sur 11.2, there don’t seem to be any noteworthy additions in terms of new features. Instead, the update seems to be primarily focused on under-the-hood improvements and fixes to different existing issues with the macOS system (you can learn more about what will come with macOS Big Sur 11.2 on this link). In other words, unless you are a beta tester or a developer, there’s probably not much of a reason to update your macOS to Big Sur 11.2 while this version is still in beta. That being said, if you want to do it, allow us to show you the steps required to update your macOS to macOS Big Sur 11.2.

How to Download and Install Big Sur 11.2 Beta on Mac

Back up your Mac using Time Machine

First, before we begin, we strongly recommend that you back up your Mac to prevent loss of important data in case there are any problems during the update installation. In most cases, there shouldn’t be any issues, but it’s always important to create a backup when making any significant changes to your system so be warned.

  1. Connect an external hard drive to your Mac using a USB, Thunderbolt, or FireWire cable – make sure there’s plenty of storage space on the external hard-drive.
  2. Select the Apple menu from the Menu Bar (top-right), and go to System Preferences.
  3. Click on Time Machine from the next window and turn the toggle button to the On position.
  4. Click on the Select Back up Disk option and select the disk that you would like to back up.
    • Important!: Before you start the process, make sure that there’s no sensitive data stored on the external hard-drive that you will be using for your backup. Time Machine will format the external hard-drive before the process begins, so if you have any sensitive files on the latter, make sure that you save them in another location before you proceed.
  5. Start the process and wait for Time Machine to format the external hard-drive and backup the selected disk.
