DISCLAIMER: Please understand that installing macOS Big Sur on your unsupported Mac is a best effort by the community. A ton of work went into getting the patcher to work! Some things might not work exactly right but it’s really really close. I would not recommend installing on a system that you count on for work or school. ALWAYS BACKUP YOUR FILES FIRST BEFORE YOU UPGRADE! Also note that certain features like sealed OS Snapshots are disabled. This is the only way to make the patcher work right now. The good news is that you are getting the latest security fixes from Apple. Some might argue that upgrading to Patched Big Sur makes your Mac safer since Apple is no longer fixing security issues on macOS High Sierra and below. Thank you!

Part 3: How to Install macOS Big Sur on an Unsupported Mac

Before the installation, make sure that you take a backup of your Mac on an external hard disk as you will lose all your data when you install the new operating system. There are several backup software like Time Machine, iCloud, Dropbox, and many more. Once you have taken a backup follow the instructions below to install macOS Big Sur on your unsupported Mac.

Step 1: First you need to download two files from the links below to complete the macOS 11 Big Sur installation on your unsupported Mac.

• macOS Big Sur PKG installer: https://developer.apple.com/macos/
• macOS Big Sur PKG install hack: https://forums.macrumors.com/simple-installer-hack-zip.926156/

Step 2: After you have downloaded these two files, unzip the hack and copy the hax.dylib file and then paste it to home folder.

Step 3: Click on Install Assistant.pkg to install required contents to your Mac. Make sure that you have enough space on your hard disk as the file will take 20.1 MB size on your computer.

Step 4: Now go ahead and tap on the Install button to install the software on the disk 'Macintosh SSD'. Once you click the 'Install' button then it will ask you to enter your password. Next, click the 'Install Software' button.

Step 5: Next, you have to boot your computer into Recovery mode. You can do that by pressing Command + R immediately on startup until Recovery option appears. In case if you have no recovery partition, you can press down Command + Option +R to get into Internet Recovery. After that, go to Utilities -> Terminal and type 'csrutil disable', followed by pressing the Enter button on your keyboard.

Step 6: Type the following two commands in the terminal. Once you apply the first command, type your login password, and then input the second command.

sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true

launchctl setenv DYLD_INSERT_LIBRARIES $PWD/Hax.dylib

Step 7: Next, run the macOS 11 Big Sur installer app that you installed from InstallAssistant.pkg a while ago. Now click on the 'Continue' button and follow the instructions to complete the installation process.

Step 8: The installation will take about 30 minutes approximately. Once the installation is successful you will see the macOS 11 Big Sur wallpaper on your Mac screen. That's it, you have installed macOS Big Sur on your unsupported Mac successfully.

Follow the above-mentioned method to install macOS 11 Big Sur on unsupported Mac devices. The method is quite easy; you just have to focus on the command line and other installation procedures.
