Part 1. Reasons for Mac Boot from USB

Booting the Mac from USB in a way gives the power back to the user.

Using an external source like the USB drive helps the user get around the problem. It provides the user access to the contents of the internal drive, assuming the data is safe and not corrupted. It also helps to repair the Mac disk with Disk Utility and other tools. Here are the top reasons why the user should choose to Boot Mac from USB:

• Allows the user to install a different version of macOS.
• It allows the user to test a new version before you make the decision to upgrade.

Part 3. How to Create Bootable USB on Mac

There are a few general guidelines that can help get your machine started which are mentioned above, regardless of the OS the user prefers. Here are the methods to create a bootable USB drive on Mac.

Creating a Bootable USB Using Terminal

The terminal is the default gateway to the command line on a Mac. It is just like the Command Prompt feature works for MS Windows. The Terminal feature ensures a hassle-free experience for the Mac user without the conventional pointing and clicking, the user just has to type the commands and the computer does the rest. The user can find Terminal in the Applications > Utility folder or it can be checked in the finder utility.

Using the Terminal feature is the most simple way to create the bootable USB drive. The user just needs to follow one easy step which is renaming the MyVolume portion of the command with the name of the drive. The name of the drive can be changed using the Disk Utility of Mac. Here are the steps required after opening the Terminal feature to create a bootable USB drive.

• Copy and paste the command which is suited for the version of the operating system into the Terminal window.
• The command for MacOS Mojave is as follows:
  sudo/Applications/InstallmacOSMojave.app/Contents/Resources/createinstallmedia --volume/Volumes/MyVolume
• Press the Return key.
• Enter the password.
• Confirm to erase the USB drive by typing Y followed by the Return key.
• The terminal will erase all the data inside the drive and create the bootable USB drive.

If there is a need to install a different version of the operating system then the user just has to replace the above-underlined command with their desired version of OS. For example, if the user wants to install Mac OS Sierra instead of Mojave then they would have to replace 'Mojave.app' with 'Sierra.app' inside the command line.

Part 4. How to Boot Mac from USB Media

After creating a bootable USB drive, the user simply needs to plug the created drive into the open port on the Mac. Here are the steps to boot Mac from the USB flash drive:

• Power on the system.
• Press and hold the Option (Alt) key on the keyboard when the computer starts.
• Select the USB drive as a startup disk when the option appears.
• The system will start the boot process off the USB drive.
• Install the operating system from the macOS utilities.
• Data can be restored by using the Time-Machine backup option.

Apple has just released the final version of macOS Big Sur to the public. You can start upgrading your compatible Mac devices by downloading Big Sur from the App Store or Settings > Software Updates. But if you prefer to completely wipe out your Mac and do a fresh install of macOS Big Sur, you will need a bootable media.

I perform a fresh install every time Apple releases a major macOS version – which usually happens once a year. This time too, I will update my Macbook Air by performing a fresh install. And to do that, I will make a bootable SD card. You can also use a USB stick aka pen drive aka flash drive and perform a fresh install.

In this quick tutorial, I will share how I make a bootable macOS memory card or USB stick, wipe my Mac, and perform a fresh install. You will need a stable internet connection and a storage media with minimum 16GB space. Before you begin, make sure you have taken backup of your Mac.

Step 1: Download macOS Big Sur

Open App Store and search for macOS Big Sur. Click Get and the Software Update window will open. Click upgrade now and it will start downloading the macOS update. If you don’t see macOS Big Sur in App Store, follow this link and choose open link in App Store.

The installer is 12GB so be patience.

Once it finished downloading, the macOS installer is placed under Applications and will run automatically. Close the setup window.

Step 2: Preparing the Storage Media

Insert the storage media you would like to use. I use a 64GB micro SD card with my MacBook Air. You can use a USB-C to USB adapter for Mac models without USB A ports and memory card slot.

Open Disk Utility.

Select the storage medium you just connected from the list on left and click Erase. Select Mac OS Extended (Journaled) from Format dropdown. Type BigSur or any other name you like. Make it simple because you will use this name in the next step.

Click Erase and wait until the media is erased.

Step 3: Making the Bootable Media

Now open Terminal and type the following command. Make sure you don’t leave any spaces. Replace BigSur with whatever name you chose in Step 2.

Press enter.

Enter your password, type Y and press enter again. The process takes roughly 20 minutes. After it’s finished, you will notice that the name of your USB stick/SD card has been changed to Install macOS Big Sur.

Step 4: Installing macOS Big Sur from Bootable Media

Right. Now you have a Big Sur bootable media. It’s time to start the installation process.

Restart your Mac. When it’s booting up (right after the chime sound), press and hold Option key until you see a screen with an option to select the startup disk.

Select Install macOS Big Sur and click continue. Let the installer load.

Now you will see the macOS Recovery screen which will ask you to select a user account which you know the password of. Choose your administrator account and enter password. Note that this is the user on your current macOS setup.

Click Disk Utility and continue. Select the volume where macOS is currently installed on your Mac. Click Erase. Leave all options as default. Click Erase again.

After the process finishes, close Disk Utility and you will return to the recovery screen. Choose ‘Install macOS’ this time and click continue.

The macOS installation process will start and your Mac will reboot a few times.

Once finished, you should see the macOS setup screen. After you are done with onboarding, you will see the desktop and are all set to start using macOS Big Sur.

The same bootable media you just made can be used to install macOS Big Sur on all your (compatible) Macs. This approach helps save bandwidth if you have more than one devices while also letting you erase all data and perform a clean install. It will also come in handy as a recovery media if your Mac software misbehaves in future.

That’s all, folks. This was a tutorial on making a bootable macOS Big Sur installation media. I hope you found it useful and I’d like to thank you for reading.
