Downgrade MacOS

I need to downgrade my software from Monterey to Big Sur, once I download the link from the website, I click on it and this is the message I get:

Install MacOs Big Sur cannot be opened from a newer version of macOS.


How can I do this?

That is correct. You cannot downgrade directly. You would need to completely erase your hard drive, removing all data, and then install the older version on the blank drive.


Maker sure you backup all the data and files you want to keep before doing the downgrade. Everything will be erased.
