In August, Apple released the macOS Big Sur Beta for its public beta testing group. The beta version of macOS will allow you to test out the new software ahead of its release during fall. The good thing about the macOS Big Sur Public beta is available to you as long as you have a compatible Mac. A point to note though, Apple does not highly recommend the installation of the macOS Big Sur Beta version on your main Mac. It is more or less a trial version. So, you can use a partition or a secondary machine. All said and done, here is a quick guide on what you need to know to install the beta version.

Which version of Mac is compatible?

Not all Mac computers are compatible with macOS Big Spur. So, here is a list of the computers that you can install the beta version on:

  • 2015 and later MacBook
  • 2013 and later MacBook Air
  • Late 2013 and later, MacBook Pro
  • 2014 and later, iMac
  • 2017 and later iMac Pro
  • 2014 and later Mac mini
  • 2013 and later Mac Pro

If your Mac computer falls in the above category, then you are good to go.

What to do before installing macOS Big Sur Public Beta

Now, you need to back up your Mac before installing the beta version. To do so, you can use the Apple Time Machine or an alternative backup setup that you have. A backup you can revert to is crucial if the beta version doesn’t appeal to you or if you need to restore your system should you run into any glitches.

Create enough space for the beta version

Before trying to install it, you will need to create space in your Mac. The macOS Big Sur Public Beta will require you to have around 20GB free space. How do you get all that space to install a beta version? Well, you can start by clearing junk from your Mac. There may be old files that you do not need or movies and videos you have already viewed. You need to delete or move them to create more space. You can check this blog for detailed steps on ways to clear junk, cache, and create space on your Mac. You can use a cleaner app to help you manage space on your Mac or perhaps use the cloud or external drive for more storage.
