Watch my 2nd video on Patched Sur before proceeding as it may better suit your needs.

Please refer to Barry K Nathan’s Big Sur Micropatcher page on GitHub if you are confused by anything.My video only covers what I had to do to get Big Sur Beta downloaded and installed.

0. Prepare USB installer with old supported version first of OSX if necessary:

1. Download macOS Big Sur Beta 11.0 (20A4300b).iso - http://download2230.mediafire.com/ka1...
Found on: https://techspite.com/download-macos-...
Make install media command:
2. sudo /Applications/Install\ macOS\ Big\ Sur\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Install

3. Next drag micropatcher.sh to the terminal window and then install-setvars.sh

4. Shut down, power on while holding the Alt key and initiate install.
5. When it is finished, do the same, but this time go into Terminal and type this command.

/Volumes/Image\ Volume/patch-kexts.sh /Volumes/Macintosh\ HD

You can start typing /V then press Tab each time to auto complete, the final “Macintosh\ HD” will be your Mac name, if your mac was called “Fred” you would type /Volumes/Image\ Volume/patch-kexts.sh /Volumes/Fred, pressing Tab will help here also if you know the first letter.

When finished, reboot and you should be good to go.
