How can I download macOS High Sierra installer?

if you already have ANY version of macOS installed, obtaining the High Sierra Installer using your existing MacOS is usually far easier than trying to work through extremely limited Recovery.

when using the Mac App Store, the download will only be provided if it can actually RUN on the system you are using to run the Mac App Store. All others will be refused and the error messages are AWFUL.

Many older MacOS downloads are supplied as an Installer-Installer. That is, the software you download, when run, will PLACE the Actual Installer in your /Applications folder, ready to be installed. This MUST be done on a Mac.
