Why does macOS High Sierra Installer automatically download in the first place?

Apple has decided to automatically download the macOS Loftier Sierra installer onto Macs running El Capitan or Sierra, a back up document states the post-obit:

If you're using OS 10 El Capitan v10.11.5 or later, High Sierra conveniently downloads in the background, making it even easier to upgrade your Mac. When the download has completed, you receive a notification indicating that High Sierra is gear up to be installed. Click Install in the notification to become started.

If you desire to install High Sierra later, only dismiss the notification. Install it at any time by opening the file named Install macOS High Sierra from your Applications folder, Launchpad, or Spotlight. Or delete the installer by dragging it to the Trash. You tin can e'er get it again from the App Store.

This aggressive automatic download push button for High Sierra was pointed out 512pixels and Tidbits, both of which make various good points about why information technology may not be a dandy thought to automatically download a 5.2GB file in the background, let lone try and install a brand new operating system, which is not without some reported problems, onto unsuspecting users, and without even backing up their computers beforehand (which would prevent a potential easy downgrade from macOS High Sierra to what yous had before).

Of course some other option that is less aggressive is to disable Notifications and alerts in Mac OS completely by enabling a 24/7 Do Not Disturb mode, which will simply forbid the "install macOS High Sierra" alerts from showing up on screen, but information technology wouldn't prevent the download. Personally, I hate notifications and alerts of all kinds on my Mac and use the 24/vii Exercise Not Disturb trick so that I'm not pestered past nagging alerts and inconsequential distractions, merely many users actually like the alerts feature and may not find that equally a reasonable alternative.

Of course if yous're already on High Sierra, none of this is applicative to you lot, and if you don't mind that High Sierra is maybe downloading in the background and pushing to install, you won't intendance much about this either. And to be perfectly articulate, this is not unique to Loftier Sierra, Apple was too automatically downloading Sierra to Macs that were running El Capitan equally well. Nonetheless, if yous don't like car-downloading large files or system software, you may appreciate stopping the behavior on your own Mac or others y'all manage.
