What's this?

It's a simple script, that automates some of the actions, required to setup Big Sur on unsupported macs.

Here's my full installation guide for Catalina-capable Macs.

Also, follow this topic on MacRumors for more info: https://forums.macrumors.com/threads/macos-11-big-sur-on-unsupported-macs-thread.2242172/.

Please report any issues in the github issues section.

This script:

• Checks if SIP disabled
• Checks if FileVault disabled (will remove in the future if error 66 not caused by FileVault), this check can be skipped
• Disables library validation
• Adds -no_compat_check to the boot-args
• Automatically downloads and extracts patcher
• Runs installer with patcher, with a little bit different, but more stable method

How to run?

Clone repository:

cd ~
git clone https://github.com/4ndv/big-sur-plz.git

Navigate to big-sur-plz folder:

cd ~/big-sur-plz

Run with default installer path:

/usr/bin/ruby big_sur_plz.rb

Run with custom installer path:

/usr/bin/ruby big_sur_plz.rb "/Users/user/Downloads/Install macOS Beta.app"

And follow the instructions

Huge thanks
