Drive-by downloads of Install macOS Monterey

[Ryan Schmidt]

I noticed copies of the Install macOS Monterey application on both the Catalina and Big Sur MacPorts buildbot build machines. I've of course never requested the download of these installers on those systems and they are configured not to update automatically and not to download new updates automatically. If you have machines running Catalina or Big Sur, you might check to see if you too have an unwanted Install macOS app in your Applications folder that you can delete to save space.
