The new Mac and MacBook operating system from Apple, macOS 11 Big Sur, is expected to be released shortly, most likely during the upcoming Apple launch event on November 10. If, however, you are anxious to find out how to download and install macOS 11 Big Sur, you will be delighted to know that it is now available for public beta.
MacOS 11 Big Sur is supposed to introduce some pretty huge changes and exciting features to the operating system that runs the best Macs, promising to be the biggest upgrade to macOS in years. And, to see what those are going to be, you won’t have to wait too long- the new macOS from Apple is now available for download as both a Public Beta and a Developer Preview.
Those models do come with a few caveats, however. They will not have all of the final release’s functionality and which come with glitches and mistakes when the program is being finalized.
We would highly suggest waiting before the final stable release of macOS 11 Big Sur later this year if you don’t want your Mac or Macbook crashing at random times while you’re working. Better still, wait to be absolutely sure if any bugs or problems have been resolved for a few weeks afterward.
However, if you want to see what it has to bring before everyone else, it is definitely worth checking out. Simply participate in the Public Beta by signing up and downloading the Public Beta Control Utility in the Beta Program. The best thing about this way of doing it? That is open. And the worst part? It’s still a beta again and can be a little buggy.
By enrolling in the Apple Developer Program, you can also download and install the utter cutting edge build of macOS 11, the macOS 11 Big Sur Developer Preview. But bear in mind, this needs a $100 (about £69, AU$ 140) charge.
Can your Mac run macOS 11 Big Sur?
Before you begin to download the macOS 11 Big Sur Developer Preview, you should make sure your Mac can run the software.
These are the Macs that you can install macOS 11 Big Sur on:
- 12-inch MacBook (2015 and later)
- MacBook Air (2013 and later)
- MacBook Pro (Late 2013 and later)
- Mac mini (2014 and later)
- iMac (2014 and later)
- iMac Pro (all models)
- Mac Pro (2013 and later)
Before upgrading to macOS 11 Big Sur Beta, back-up your Mac
Whenever you update your operating system, and especially when you try an early Developer Preview or beta version, we strongly suggest that you back up the files on your Mac, so you can easily restore your computer to its previous working order if something goes wrong.
Make sure your Mac is backed up until you download and update the macOS 11 Big Sur beta.
How to participate in the Developer Program for Apple
If you really want to try the macOS 11 Big Sur Developer Preview, and you’re not already registered with the Apple Developer Program, go to the registration page of the Apple Developer Program, which will show you what you need to sign up for it.
You’ll need an Apple ID and your basic personal details will be given. To start, click on ‘Start Your Enrollment’ and then follow the directions. Now, in order to enroll, you would need to pay $100 (about £69, AU$140).
How to Preview MacOS 11 Big Sur Developer Download
Once you have signed up for the Apple Developer Program, the macOS 11 Big Sur developer preview is available for download. Go to the macOS Big Sur website for Apple Developers. A blue ‘Download’ button should appear in the top-right corner.
Click on it, then log in with your account with your developer. You should see a button on the next page that says ‘Install Profile’ for macOS Big Sur (you may have to scroll down to find this).
Click it, then the file is downloaded. Now, in Finder, open the Downloads folder and choose ‘macOS Big Sur Developer Beta Access Utility’. Next, to begin installation, double-click the macOSDeveloperBetaAccessUtility.pkg file.
Device Settings will open during this process and search for macOS updates. When the Developer Preview update is found, click ‘Update’. Restart your Mac, open the Mac App Store, and press ‘Updates’ if the update is not found.
After the entire macOS 11 Big Sur Developer Preview has been downloaded, a new window will open to prompt you to agree to the terms and conditions of Apple. From there, follow the instructions for the new operating system to be installed.
How to Enter the Public Beta of MacOS Big Sur
First of all, if it’s your first time joining in on a macOS public beta, welcome. You’re going to have to head over to the macOS Public Beta signup page and sign into your Apple account if you want to get in on the action.
It will then ask you to confirm that, in fact, you want to enter the beta. You’ll see a variety of steps that Apple has set out in order to install the Beta once that’s out of the way. The first is to backup your Mac, but you’ve already done that, right?
Next, it will give you a connection to the macOS Public Beta Access Utility to download. Basically, this is just a program you’re going to run on your Mac that will let you download the update to the OS. Install the program and obey the instructions on the screen.
You should see the option to download the macOS 11 Big Sur Public Beta from the Device Preferences app once that’s completed. This is going to be a meaty download, so give it a bit of time.
A window will pop up when it’s done downloading that will direct you through the installation. This, again, is probably going to take some time. Leave your Mac alone and let it do its thing until the screen goes off and you see the Apple logo with the progress bar under it.
During this method, if you get irritated and turn your Mac off, you might potentially cause some problems, like corrupting your macOS installation. So, be polite, please.
Once macOS Big Sur is up and running, if there is another public build available, you should get notifications. From there, whether to keep updating or not is up to you. And, you’re going to have to join the Developer’s program if you want to be on the cutting edge to get the builds before the public.
