How to Downgrade macOS Monterey to High Sierra (2022)

Bot Bot, Not vonting,

I can delete the installation media after?

Thank you so much! Worked perfectly!

disk utility doesn't want to erase my internal disk!

I bypassed my 2011 macbook by installing Monterey. Broke after 3 months. Quarter fan spin issue, corrupt SPI Rom. I have no idea what that is. That's what the Mac Tech told me. I had to revert back to high Sierra

Thank you very much, it worked perfectly on a macbook air 2017. Today February 05, 2023. Greetings from Peru!
