Notes

macOS Big Sur continues the list of Central California landmarks as well as marks the new operating system for Apple. Those who tried it say that it’s more stable. It also sports a refreshed version of Safari that is 50% faster than Chrome. Here’s how to perform a clean install of macOS Big Sur with pictures and helpful tips along the way.

What is a clean install? (Big Sur or any other macOS)

A clean install means that you install the macOS onto the erased drive.

Why is clean install more preferable?
A clean install is the opposite of macOS upgrade. You format your hard drive, and therefore, it keeps no leftovers from the previous macOS.

• macOS performs faster
• You get rid of apps you don’t use
• Persistent issues may go away

Basic steps to clean install macOS Big Sur

The first step is to clean and back up your Mac to some external source. Then, you’ll need to download macOS Big Sur Beta package to your Applications. Next, you’ll need to create a bootable USB installer (involves another external drive). And lastly, we’ll use Disk Utility to erase your Mac and install macOS Big Sur using the bootable USB device.

1. Clean & Back up your Mac

Cleanup

Cleaning your Mac is generally a healthy practice but since we’re about to back your Mac up, it’s worthwhile to get rid of system junk first. After we’ve cleaned your Mac, you’ll end up with a refreshed system ready for a Time Machine backup.

Time Machine will make a snapshot of your system. And just like you “do yourself up” before a photo shoot, we’ll ensure your Mac looks good and tidy. To clean your machine automatically, you can run CleanMyMac X. This tool is the best-ever cleaning utility for Mac (no joke), and it’s been notarized by Apple.

Download the free version of CleanMyMac X cleaner here.
Install the app and click on System Junk to perform the scan.

Back up your Mac

Now, you’re ready to back up your computer. There is a tool built just for that purpose, you guessed it, Time Machine. Time Machine needs a storage source onto which it will copy your system.
So, you’ll need an external drive. This is the first external drive that we will use to clean install macOS Big Sur. This is the reserve backup option for the worst-case scenario.

• Go to System Preferences > Time Machine.
• Connect an external drive (that’s more spacious than your current system).
• Select this Disk as a backup source in Time Machine.
  

Well done. The preliminary steps are done with, and we’re ready to clean install macOS Big Sur.

2. Download macOS Big Sur installer package

You can install Big Sur only if your Mac is currently running macOS Catalina.

macOS Big Sur is now only in Beta. It hasn’t gone public yet, so you have to be an Apple Developer to download it. Don’t worry. You can obtain this highly noble status when you enroll in Apple Developer program. But for now, we’ll assume that you’ve signed up as an Apple Developer and have your account set up.

Alternatively, visit: https://betaprofiles.com/
This is the best open source for developer betas. Or if you are an Apple Developer:

• Go to developer.apple.com using Safari.
• Click on Discover.
• Now choose the macOS platform, and click Download.

After you’ve chosen among Operating Systems, you’ll get to this screen.

This will not download the macOS itself, but for now, only a pre-install package.

• Go to your Safari Downloads.
• Click on macOSDeveloperBetaAccessUtility.dmg
• This will take you to the installer box.

The final destination of the above steps is the Software Updates window. It should have launched automatically but if it hasn’t, you’ll find it in System Preferences > Software Updates.

• Click Upgrade Now
  

Wait for the installer to download onto your drive. You will see the macOS Beta intro screen.

Don’t click Continue for now but close this window by choosing Quit Install.

We only want to make sure that the app called Install macOS Beta.App is now firmly sitting in your Applications.

This is the file we’ll use later to run the clean install of macOS Big Sur via Disk Utility.

Now, and only now have we come close to clean installing macOS Big Sur. This is only a short stop on the road, so catch your breath, and let’s move along.

3. Create a bootable Big Sur installer

Now, it’s time to grab another USB flash drive and connect it to your Mac. This drive should have at least 16 GB of storage space.

Wipe the drive clean with Disk Utility

1. Pick this drive and click Erase in the top menu.
2. Double-check what you’re erasing.
3. Make sure the USB drive is shown as “Untitled”
4. Under Format, choose: Mac OS Extended (Journaled)

All data on that disk will be lost, so beware.

Go to Terminal (Phew, we’re almost there)

This step will actually create the source disk so we can install Big Sur from bootable USB.

Launch Terminal app from your Launchpad.

Paste in the following command:

sudo /Applications/Install macOS Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

Type in your admin password and press Return and Y to confirm the action.

This command creates a bootable USB installer based on macOS Beta. app, which we’ve previously placed in your Applications.

4. Erase your startup drive in Disk Utility

It’s time to wave goodbye to your current configuration. Remember, we’ve already cleaned it up from junk with CleanMyMac X and backed it up onto our first reserve USB drive.

Now, start your Mac in Recovery mode:

• Turn off your Mac and hold down Command + R.
• Choose Disk Utility from the menu.
• Choose your main startup drive and click Erase.

Voila! Your Mac is now formatted. What you can do now (actually, this the only thing you can do now) is to clean install macOS Big Sur 11 from the connected USB installer drive. If it’s not connected, connect the bootable USB installer now.

1. Go back to the original Disk Utility screen
   (If you can’t return to Disk Utility, restart your Mac and hold down the Option key)
2. Click Install macOS and choose to install it from the selected USB drive.
3. Click on “Install macOS Beta”

How do I regularly install macOS Big Sur?

The regular install is done via upgrading your current macOS. That is, you don’t erase your entire disk. When the new macOS Big Sur is officially released, you just open the App Store > Updates.

Or even better, go to your System Preferences > Software Updates

How to reinstall macOS Big Sur?

If for some reason your Big Sur macOS doesn’t work as expected, you can reinstall it by sending your Mac into Recovery Mode.

• Restart your machine and hold down ⌘ + R
• Choose Reinstall macOS
