#1.1. There are 2-ways to download macOS Big Sur from Apple. If you have a developer account then visit developer.apple.com. Click on Discover > macOS > Download. Sign in with your developer account then scroll down and click the Install Profile button for macOS Big Sur Beta install. if you don’t a developer account then download macOS Beta profile from betaprofiles.com. #1.2. After downloading the macOS Beta Access Utility.dmg open it. When the access utility window opens, Right-click on macOS Beta Access Utility.pkg then click Open > Continue > Agree > Install > Enter your Password > Install software > Close. #1.3. Finally, the Software Update window will open then you can start to download the macOS Big Sur directly from Apple’s server. So click Upgrade Now and wait for the download process to finish. It may take 10-20 minutes depending on your internet speed. #1.4. When the download of macOS Big Sur is finished, make sure to quit the installer by click on Install macOS Big Sur > Quit Install macOS or pressing Command + Q. #2.1. Once macOS is downloaded then Open Terminal and type the following command to create an empty disk image. Type your password when prompted. #2.2. Next, Mount the disk image to /Volumes/BigSur. #3. Now will use the Createinstallmedia command to make the disk image bootable with macOS Big Sur. #4. Unmount the Disk Image which is formatted from BigSur to Install macOS Big Sur and bootable with macOS Big Sur ISO image. #5 Covert and rename the Disk Image to ISO Note: running the rm -rf commands will do the cleanup and remove all the unnecessary file (disk image) from the /tmp folder. Although if you don’t do it then it will be automatically be removed after a while. After running all the commands properly you should end up with a macOS Big Sur ISO image file on your Desktop.
