How to Install macOS Big Sur on a Mac

This year, the new macOS 11 update comes with a major visual overhaul inspired by iOS. Apple said macOS Big Sur features a new Control Center, lots of Safari improvements, widgets, and many more. Ready to check out all these new updates on your Mac now? Here is know how to install macOS Big Sur on your Mac.

What to Do Before Updating the new macOS Big Sur

We’ve been waiting for this macOS update since it was first unveiled during Apple’s WWDC back in June. And, now it’s finally available for public download since November 12. So, you should receive an update notification by now.

However, if you haven’t seen it yet, then you can install the new update by checking “System Preferences” to initiate the download. Alternatively, you can access the update file through the App Store on your Mac or Apple’s website too.

On top of that, there are still a few things you should do before installing the macOS Big Sur update.

Make Sure your Mac is Compatible

Updating to a new macOS is totally free. However, not every Mac can download the new Big Sur. So, make sure you have a supported device before installing this update.

Here is the list of compatible devices, according to Apple:

  • MacBook: 2015 and later 
  • Mac Mini: 2014 and later
  • Mac Pro: 2013 and later 
  • iMac: 2014 and later
  • iMac Pro: All models
  • MacBook Air: 2013 and later
  • MacBook Pro: late 2013 and newer

Back up Before Upgrading to macOS Big Sur

Now, when you know your Mac is ready for the new update, it’s time to back up! Doing this helps protect your Mac from data loss or corruption in case something goes wrong during the process. So, make sure your Mac is fully backed up before following the next steps. Also, here is our detailed guide on how to back up your Mac, if you need it!

The new macOS Big Sur weighs in just over 12GB, but you’ll probably need about 16GB of free disk space for this update. 

Follow these steps to download and install macOS Big Sur:

  1. On your Mac, start the download by going to Apple’ website or the Mac App Store.
  2. Either way, click “Upgrade Now” or “Get”.
  3. In the pop-up, choose “Download” if you use Mac App Store.
  4. After the download is complete, the installer will automatically open.
  5. Click “Continue” and follow the instructions.

Note: This process might take a while depending on your internet connection. Therefore, don’t close your MacBook’s lid or put your Mac to sleep during the installation process.

Although many Mac users have succeeded in initiating the macOS Big Sur, we recommend you wait until a more stable version comes out.

If you already have macOS Big Sur installed on your Mac, let us know how your experience with the update has been so far.
