Why Wont Mac Os High Sierra Download _BEST_

My mac book pro has Mojave installed. But I want to make downgrade to high Sierra. Because mojave doesn't run the programs I need to run. When you go to the app store and click on "Download", the system checks for mac os updates and offers me to download Catlina instead of High Sierra. Can you tell me how to download the file to install High sierra?

I got a solution that worked!!!if you are on high sierra or mojave, firsr install catalina by searching catalina installer and you will get a apple site link. Click catalina installer and you will be redirected to app store. Install catalina first and then you can install big sur or monterey without this null error

I am trying to install mac os high sierra on my new mac running catalina using parallels. I am getting a message that Parallels does not support anything beyond Snow Leopard. Is that correct or am I doing something wrong.

After you check compatibility, go the following steps to upgrade to High Sierra/Mojave/Catalina/Big Sur/12 Monterey: make a backup of your Mac > make sure you have a reliable Internet connection > download macOS High Sierra or higher version > begin installation > allow installation to complete.
