How do I download Mojave for my older Mac from a Mac running Big Sur?
I am trying to download macOS Mojave to create a USB installer to restore another older mac that I have. I tried following the directions in this page (https://support.apple.com/en-us/HT201372) but when I click on the "Get" button in the App Store for macOS Mojave, it opens up a window in System Preferences Software Update saying the update could not be found. I don't want to downgrade this computer, I just want to download a file to create a bootable USB for another Mac.
MacBook Pro 16″, macOS 11.6
