Downgrade macOS Monterey to macOS Catalina on Unsupported Mac 

Thank you very much, worked perfectly! Just on intel based Macs, after you restart, keep OPTION key pressed for the boot option to appear.

It works! Thank you so much! I used an iMac to figure this out by watching this tutorial video and... Boom! I got macOS Catalina! Now It's time to say goodbye to macOS Monterey and hello to macOS Catalina! Thank you so much, Mayunix!

If you do not see 'Install MacOS Catalina' option on restart then restart again and press and hold 'option' button

There is an error whenever i launch the terminal stuff. It starts well then it says error error. The file’s name went from untitles to install macos catalina tho. But i didn’t see anything after restarting.

When I restart it there is no option to install the mac os catalina :(
