 OS support data is updated by module once a week from MunkiReport's supported_os module GitHub page. Can be manually updated from admin page. Module will use data contained within module if unable to access OS support data on GitHub.
 
 Shipping OS versions from [https://mrmacintosh.com/can-i-upgrade-or-downgrade-macos-every-mac-from-2006-2020/](https://mrmacintosh.com/can-i-upgrade-or-downgrade-macos-every-mac-from-2006-2020/)
