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

Unable to upgrade from Beta 2 to Beta 5

I understand that this might be not an issue with your tool, but might be interesting to other users.

I had upgraded my Mac with Beta 2 using your excellent tool. Then I learned that Beta 5 was out, so I gave it a try again. Only this time the installer refused to recognize the destination (where Beta 2 was installed) as a valid destination.

I'm not sure if there's anything that can be done, but other users may want to know this.

Question: Will the Big Sur Beta be updated to the GM release when it becomes available?

As the title suggests, will the Beta that is installed with your script automatically update to the official release version once it's made available by Apple?
