1. Clean up your drive and back it up

A clean new install is always a safe choice. It’s often recommended that you free your startup drive from outdated cache files and debris from old apps. You can clean your Mac to make sure that these redundant items don’t stand in the way of your fresh new macOS.

To clean your hard drive without fuss, run a cleaning utility.
For example, you can run CleanMyMac X — this tool is notarized by Apple and is safe.

Launch it and follow the prompts on the screen.

This step ensures your Mac is free from unseen junk — you can expect to remove a few gigabytes of garbage. The app also checks your drive for viruses as a bonus.

Now, back up your hard drive

Now that your hard drive is sparkling clean, you can prepare the backup option. New macOS releases are prone to crashes, so you’ll need a “save” you can always go back to should things go wrong.

Click on Launchpad > Time Machine

2. Go to Software Updates

Since its public release, macOS Big Sur can be downloaded in a usual way from the Mac App Store. But it's even easier to find it in your Software Updates window in System Preferences.
Go to the System Preferences > Software Updates...
If you see macOS Big Sur there, click Upgrade Now

3. Download Big Sur installer package

You will need to allow this download, after which you’ll be ready to run the macOS Big Sur Installation app. It will appear in your Applications.

Go to your Applications and find the file called 'Install macOS Big Sur'

A few more clicks and checkboxes down the road and you’ll be installing the macOS itself.

macOS Big Sur download takes up around 12 GB of hard disk space.

MacBook Air, MacBook Pro, Mac Pro — from 2013 onwards.

Cautions and troubleshooting

Free space

As stated above, having enough free space on your drive is crucial. The new Big Sur macOS will be automatically downloading lots of patches, plugins, and other things. So it’s always a question, how much storage you will end up needing.
To free up tons of space without much fuss, grab a free copy of CleanMyMac X by MacPaw. You will probably like this app for Mac maintenance.
Activation Lock

The whole issue with iCloud, iTunes passwords and needing to reset them is every Mac user’s headache. Protect yourself before you download macOS Big Sur installer: Double-check your actual password for Apple services. Or, as another idea, turn off the Activation Lock before Big Sur installation. This requires that you sign in to iCloud.com > Find my Mac and remove your device from your Account.

Installation freeze-ups

macOS Big Sur is still a baby, so, quite often, it will freeze during the installation. For this reason, some people never install new macOS versions until all bugs have been fixed. Don’t abrupt the process and stay patient. Also, ensure that your internet connection is stable during that time. But you have prepared the backup, just in case, right?

What’s there to see in Big Sur

You have probably watched the snippets of Big Sur during WWDC keynote. It’s impressive enough in terms of added features, although admittedly, not as revolutionary as its counterpart, iOS 14. If you decided to follow the above steps and download Big Sur, here’s what you can expect.

The looks
The macOS interface received a much-needed facelift. Windows and toolbars feel larger, and they are more rounded. Many folks agree that the Dark Mode looks much better on Big Sur compared to Catalina. The new Finder looks so weightless and thin!

Control Center

The Control Center is praised by many. A quick pane to manage settings like sound and brightness right at your fingertips is convenient. And while you’re doing all this, you can skip music tracks. By the way, if you ever used CleanMyMac X and its Assistant, you’ll find the new Control Center strikingly familiar. Might there be a coincidence?

Safari will check your entered passwords for potential password leaks that had happened in the past. In macOS Big Sur Safari takes a hit on Chrome, promising much faster speeds. Luckily, you can prove this on your own Mac when you download macOS Big Sur installer.
