Sorry you're wrong because it does work if you follow @crazybirdy's "how to" guide carefully . With no information on what you did or what errors appeared, eg log files, its impossible to help you.
Some tips on preparing the target volume manually (the automated script 14MBRinstallerMaker doesn't seem to prepare the target volume fully if it is GUID formatted) ...
.IAProductInfo is a hidden file and needs to be copied to the root / of the Target Volume, all other install files should be placed in "/macOS Install Data" folder
Determine the volume UUID of the Target Volume (for use in editing .IAProductInfo and minstallconfig.xml) with terminal
diskutil info "Target_Volume_Name" | grep UUID
The value to enter for <key>IAEndDate</key> can also be determined from terminal (credit to @PikeRAlpha's blog post)
date -v -2H "+%Y-%m-%dT%H:%M:%SZ"
After the target volume is fully prepared, you should point Clover to boot the Disk1mbrInstaller volume and not macOS Install
